Most advertisers either obsess over Quality Score to the point of distraction or ignore it entirely because Smart Bidding handles the account. Neither approach is right. Quality Score is not the primary metric you manage Google Ads by. But it is a direct, measurable tax on every click you pay for when it is low, and a meaningful discount when it is high. In 2026, with cross-industry CPCs rising 12 percent year over year to an average of $2.96, paying a 30 to 50 percent premium on every click because of low Quality Scores is no longer a minor inefficiency. It is a structural cost problem.
This guide covers Google Ads Quality Score completely: what it actually measures, the exact CPC discount and penalty at every score level from 1 to 10, how each of the three components works and what drives each one up or down, the specific fixes with the highest ROI, and how Quality Score interacts with Smart Bidding in 2026. By the end you will have a clear action plan for finding every low-score keyword in your account and fixing the right component for each one.
What Google Ads Quality Score Is (and What It Is Not)
Quality Score is a diagnostic metric assigned to each keyword in your Google Ads Search campaigns on a scale of 1 to 10. It reflects Google's estimate of the quality and relevance of your keyword, your ad copy, and your landing page relative to what a user was searching for when your ad appeared. A higher Quality Score signals that your ad and landing page deliver a good experience for that specific search query. A lower Quality Score signals a mismatch somewhere between the query, the ad, and the destination.
The score is calculated from three components: Expected Click-Through Rate (how likely your ad is to be clicked), Ad Relevance (how closely your ad matches the search query's intent), and Landing Page Experience (how relevant and useful your landing page is for users who click). Each component is rated as Above Average, Average, or Below Average. The combined evaluation of all three produces the 1 to 10 number displayed in your keyword report.
What Quality Score Is Not
Quality Score is frequently confused with two other metrics that have very different implications. It is important to distinguish all three before acting on any of them.
✅ Quality Score (1-10) - Act On This
- Assigned per keyword on Search campaigns only
- Directly influences Ad Rank and actual CPC paid
- Reflects Expected CTR, Ad Relevance, and Landing Page Experience
- Has real financial impact at every score level above or below 5
- Diagnostic tool: improvements here reduce cost per click immediately
- Available in your Keywords report - add the Quality Score column
❌ Ad Strength and Optimization Score - Different Things
- Ad Strength is an ad-level diagnostic for RSA asset variety only
- Ad Strength has zero direct impact on auction performance or CPC
- Optimization Score is a sales metric measuring Google recommendations reviewed
- Optimization Score reflects Google's commercial interests, not account health
- Neither Ad Strength nor Optimization Score affects your Quality Score
- Do not confuse improving these metrics with improving Quality Score
Do not optimise campaigns primarily to improve Quality Score numbers. Optimise campaigns to improve user experience across the keyword-ad-landing page journey. Quality Score improvement follows naturally from genuine relevance improvements. Chasing the score itself - stuffing keywords into headlines, creating superficial landing page keyword density, or splitting ad groups into hundreds of single-keyword units - produces marginal QS changes without meaningful business results. The right question is always "Is this a genuinely better experience for the user searching this query?" Quality Score will reflect the honest answer.
How Quality Score Directly Affects Your CPC and Ad Rank
Quality Score is not just a diagnostic number. It is a live financial multiplier on every click you pay for. Google compares your Quality Score to the industry average of 5 and applies a discount or a penalty based on the gap. The effect is immediate, significant, and cumulative across every impression your keywords generate.
The mechanism works through Ad Rank: your position in every auction and the price you pay is determined by Max CPC bid multiplied by Quality Score multiplied by the expected impact of your ad assets. This means a competitor with a lower bid but a higher Quality Score can win better positions at lower cost than you, even when you are bidding more per click. It also means that improving Quality Score delivers a compound benefit - lower CPC and better Ad Rank simultaneously - without changing your bid at all.
The Quality Score CPC Discount and Penalty Table
Google calculates the CPC adjustment by comparing your Quality Score to the baseline of 5. The table below shows the exact discount or premium applied at each score level. With the cross-industry average CPC at $2.96 in 2026, these percentages translate to real dollars per click across every keyword in your account.
| Quality Score | CPC Impact vs Score 5 | Real-World Example at $2.96 avg CPC | Status |
|---|---|---|---|
| 10 | ▼ 50% discount | Pay $1.48 instead of $2.96 per click | Excellent |
| 9 | ▼ 44% discount | Pay $1.66 instead of $2.96 per click | Excellent |
| 8 | ▼ 37% discount | Pay $1.86 instead of $2.96 per click | Good |
| 7 | ▼ 28% discount | Pay $2.13 instead of $2.96 per click | Good |
| 6 | ▼ 17% discount | Pay $2.46 instead of $2.96 per click | Average |
| 5 | No adjustment | Pay $2.96 per click (baseline) | Baseline |
| 4 | ▲ 25% premium | Pay $3.70 instead of $2.96 per click | Below Average |
| 3 | ▲ 67% premium | Pay $4.94 instead of $2.96 per click | Poor |
| 2 | ▲ 150% premium | Pay $7.40 instead of $2.96 per click | Rarely Shown |
| 1 | ▲ 400% premium | Pay $14.80 instead of $2.96 per click | Rarely Shown |
If your account has 20 keywords stuck at Quality Score 3 each generating 500 clicks per month at an average CPC of $2.96, you are paying a 67 percent premium on 10,000 clicks monthly. That is approximately $14,800 per month instead of $8,850 at a baseline score of 5 - a waste of $5,950 per month on nothing but low Quality Score penalties. Improving those 20 keywords from a 3 to a 7 would save $6,700 per month while improving ad position simultaneously. This is the financial case for treating Quality Score as a priority in every account audit.
Component 1: Expected Click-Through Rate
Expected Click-Through Rate (Expected CTR) is Google's prediction of how likely your ad is to be clicked when it is shown for a specific keyword, normalised to remove the effect of ad position and other factors. It is one of the three components of Quality Score and, for most accounts, the one with the most direct relationship to ad copy quality. If your Expected CTR is rated Below Average, your ad copy is the primary problem.
Expected CTR is calculated from two sources: your historical CTR for this keyword and similar keywords in your account, and a predictive model based on how users have responded to ads matching this query pattern across Google's entire advertiser base. A new keyword with no history inherits the expected CTR from similar keywords. A keyword with a long history of low CTR has that history working against it, which is why old, unoptimised keywords often carry persistently low Expected CTR ratings even after ad copy improvements - the history needs time to update.
Google's prediction of how likely users are to click your ad when it appears for this keyword. Reflects both your historical CTR data and predictive modelling across Google's full advertiser dataset. The most directly controllable component through ad copy improvements.
Causes of Below Average Expected CTR
- Headlines do not include or reflect the search query When a user searches for "Google Ads management Dubai" and your first headline says "Grow Your Business Today," there is no visible connection between what they searched and what your ad offers. Users scan ads for confirmation that the result is what they were looking for. Headlines that mirror the query language generate significantly higher CTR than generic aspirational headlines because they pass the immediate relevance check
- Weak or absent value proposition in the first two headlines Users typically read the first two headlines and the description. If your value proposition (what makes you better, faster, cheaper, or more trustworthy than competitors) does not appear in the first two headlines, you are competing on equal footing with every generic ad in the results. Specific, differentiated value propositions ("Free Audit - Results in 30 Days", "Rated 4.9/5 by 200+ Clients") outperform generic copy by 20 to 40 percent on CTR in competitive verticals
- Missing or underutilised ad assets reducing ad real estate Sitelink assets, callout assets, structured snippets, image assets, and call assets all expand the physical size of your ad in search results. Larger ads capture more visual attention and generate higher CTR, all else equal. An ad with 6 sitelinks, 4 callouts, and 2 structured snippets takes up significantly more screen real estate than a bare RSA without assets. Google confirmed that asset inclusion directly improves Ad Rank and Expected CTR signals. Every campaign should have at minimum 4 sitelinks, 4 callouts, and 2 structured snippets active
- Ad group too broad to serve a single relevant ad When an ad group contains 30 different keywords covering different user needs and intents, no single RSA can be highly relevant to all of them. The ad is forced to be generic to remain applicable to the full range. This produces moderate CTR across all keywords rather than high CTR on any of them. Tighter ad groups with closely related keywords allow one highly relevant ad to serve the entire group with genuine precision
- Persistent low historical CTR on the keyword If a keyword has accumulated months or years of low CTR history in your account, that history is a drag on Expected CTR even after you improve the ad copy. Google's model incorporates historical performance. The fix requires either sustained CTR improvement over 4 to 8 weeks to update the historical signal, or pausing the low-CTR keyword and adding it to a new, tighter ad group with fresh history
How to Improve Expected CTR
-
Include the primary keyword in at least one headline
In your RSA, pin the primary keyword phrase or a close variant in Headline 1 or 2. Do not rely on Google's "optimised" rotation to serve the keyword-inclusive headline when it matters most. Having the query language visible in the headline is the single most consistent CTR improvement across all campaign types and industries.
-
Write a specific, differentiated value proposition in Headline 2
What makes you the better choice for this specific query? Free consultation, same-day delivery, money-back guarantee, specific years of experience, specific rating from reviews, specific price advantage - any concrete differentiator outperforms generic copy. Avoid "We Are the Best" and "Award-Winning Services" - these are so common they have no CTR signal strength. Write specifics: "Dubai's #1 Rated Google Ads Agency", "Free Audit - Results Within 30 Days".
-
Add all available ad assets to every campaign
Go to Assets in your campaign and add: minimum 4 sitelinks (each pointing to a specific relevant page, not the homepage), 4 callout assets (specific features or benefits in under 25 characters each), 2 structured snippets (services, products, or certifications), and a call asset if phone calls are a valid conversion path. Image assets are also worth adding for shopping and display-eligible campaigns. Each asset type that qualifies for display increases your ad's visibility and expected click rate.
-
Review RSA asset performance and replace Low-rated headlines
In your RSA, click View Asset Details. Google rates each headline as Low, Good, or Best based on relative CTR performance. Any headline rated Low after a sufficient impression volume (typically 1,000 or more impressions) is underperforming. Replace it with a new variant that tests a different angle: a different benefit, a different tone, or a specific number or credibility signal. Do not replace all headlines at once - change two or three at a time to maintain performance continuity.
-
Use the Description lines to reinforce the click decision
Descriptions rarely receive as much attention as headlines during ad optimisation, but they appear below headlines and contribute to the overall expected click probability. Use descriptions to address the top objection for this query's audience (price, credentials, trust, speed) and end with a clear, specific call to action that matches what users will find on the landing page: "Book Your Free 30-Minute Audit" rather than "Contact Us Today".
Component 2: Ad Relevance
Ad Relevance measures how closely your ad copy matches the language and intent of the search query that triggered it. It is the most structurally fixable component of Quality Score because it is almost entirely controlled by how your ad groups are organised and how your ad copy is written. Unlike Expected CTR which depends partly on historical data, and Landing Page Experience which involves your website infrastructure, Ad Relevance depends entirely on decisions you make in the Google Ads interface.
A Below Average Ad Relevance rating almost always means one of two things: your ad group contains too many diverse keywords for a single ad to be genuinely relevant to all of them, or your ad copy does not reflect the core language of the queries triggering it. Google evaluates relevance by comparing the themes, language, and intent of your ad to the specific query - not just whether the keyword appears somewhere in the ad.
How closely your ad copy matches the intent and language of the search query. The most structurally controllable component - almost entirely determined by ad group organisation and how specifically the ad copy is written for the keywords in each group.
The Root Cause of Below Average Ad Relevance
The most common structural cause of Below Average Ad Relevance is ad group bloat - ad groups containing dozens of semantically different keywords all being served by one generic ad. If your "Google Ads Services" ad group contains keywords ranging from "google ads agency London" to "PPC management pricing" to "how to set up google ads" to "google ads for small business," no single RSA can be genuinely relevant to all four of those query intents simultaneously. The ad becomes generic by necessity.
The second most common cause is competitor keywords in ad groups built around your own services. When you add competitor brand terms to an ad group with your own service keywords, the Quality Score for those competitor keywords will almost always be Below Average on Ad Relevance because your ad copy cannot legitimately say you are the competitor's product. Competitor keywords almost always need to be isolated in dedicated ad groups with ad copy specifically written to address the comparison intent.
How to Improve Ad Relevance
-
Audit oversized ad groups and split by theme
In your Keywords report, filter by Ad Relevance: Below Average. For each flagged keyword, check what ad group it belongs to and how many other keywords share that ad group. Any ad group with more than 15 to 20 keywords that span different user intents needs splitting. Group keywords by what the user is specifically trying to accomplish - "best google ads agency," "hire google ads manager," and "google ads management company" all share the same intent and can share an ad group. "Google ads pricing" and "google ads course" do not share the intent and need separate groups with different ads.
-
Write ad copy that explicitly addresses the query theme
For each tight ad group, write headlines that directly use the language of the primary keyword. If the ad group is built around "conversion tracking setup," at least one headline should use that phrase or a direct variant. The RSA system means you have 15 headline slots - use them to cover different aspects of the theme rather than writing 15 generic variations of the same message. Headlines that mirror the query language score higher on Ad Relevance because they demonstrate specific relevance to that specific intent.
-
Isolate competitor keywords in dedicated ad groups
If you are bidding on competitor brand terms, create a dedicated ad group for them with ad copy specifically written for comparison intent. Headlines like "vs [Competitor] - See Why We Win" or "[Competitor] Alternative - Free Trial Available" are more relevant to the query than generic service headlines and will perform better on Ad Relevance and CTR. Do not mix competitor keywords into ad groups built for your own services - they will drag down the Quality Score for your own keywords.
-
Match keyword match types to ad relevance goals
Broad match keywords by definition trigger a wider range of queries, many of which may not closely match your ad copy. If Ad Relevance is Below Average on a broad match keyword, check the Search Terms report to see what queries it is actually triggering. If the triggered queries span too many different intents for your ad to be relevant to all of them, either tighten the match type to phrase or exact, or add negative keywords to exclude the irrelevant intent clusters.
Dynamic Keyword Insertion (DKI) automatically inserts the triggering keyword into your headline, potentially improving Ad Relevance ratings. However, DKI with broad match keywords can produce headlines that are technically keyword-matched but nonsensical or off-brand when the keyword variant is unusual. Use DKI only in tight ad groups where you are confident every possible keyword variation produces a readable, professional headline. Always set a fallback default text that makes sense if the keyword insertion fails or produces a too-long headline.
Component 3: Landing Page Experience
Landing Page Experience is the most technically involved component of Quality Score and, in 2026, increasingly the most important one. Google's 2026 update to landing page quality assessment increased the weight of page load speed to 35 percent of the landing page score (up from 20 percent in 2025). Pages loading under 2.5 seconds on mobile with content that directly matches the ad messaging achieve Quality Score 8 to 10. Slow, generic, or misaligned pages drop to 4 to 6.
Landing Page Experience reflects Google's evaluation of three things: how relevant and useful the page content is for users arriving from this specific query, how fast and accessible the page is on mobile devices, and how clearly the page fulfils the intent that drove the search. A user who searches "Google Ads management Dubai" and lands on a generic homepage with no mention of Google Ads or Dubai will have a poor experience - Google knows this and rates the landing page accordingly, adding a persistent drag to every keyword that points to that page.
Google's evaluation of how relevant, fast, and useful your landing page is for users clicking the ad. Now factors page load speed at 35% of the component score in 2026. Requires both technical performance and content relevance improvements for Below Average ratings.
What Google Evaluates in Landing Page Experience
- Page load speed on mobile (35% of landing page score in 2026) Run your landing page through Google PageSpeed Insights (pagespeed.web.dev) and check the Mobile score. Pages with a Core Web Vitals Largest Contentful Paint (LCP) above 2.5 seconds are definitively Below Average on this dimension. Pages with LCP above 4 seconds are in the Poor range. The fastest fixes are: compress and serve images in WebP or AVIF format, eliminate render-blocking JavaScript, implement lazy loading for below-fold images, and use a Content Delivery Network (CDN) to reduce geographic latency
- Content relevance to the search query The primary headline on your landing page should directly mirror or reinforce the primary message in your ad. If your ad headline says "Google Ads Management in Dubai" and your landing page headline says "Welcome to Our Agency," there is a message mismatch that harms both Landing Page Experience and conversion rate simultaneously. Google uses Natural Language Processing to assess whether the page content is substantively relevant to the search query - not just keyword presence but genuine topic alignment and depth
- Mobile usability and clarity of the conversion path A landing page that functions well on desktop but requires horizontal scrolling, has buttons too small to tap, or hides the CTA below multiple screens of content on mobile provides a poor user experience for the majority of Google Ads traffic. Check your landing page in Google Search Console under Core Web Vitals and Page Experience reports. Mobile usability errors (tap targets too close together, text too small to read, content wider than screen) all contribute to Below Average Landing Page Experience ratings
- Page transparency, trustworthiness, and absence of intrusive interstitials Google penalises pages that obscure content with large interstitial ads or pop-ups immediately on page load, pages without clear contact information or privacy policies, and pages that present misleading content relative to the ad that preceded them. These signals feed into the overall quality evaluation alongside speed and relevance
How to Fix Below Average Landing Page Experience
-
Run PageSpeed Insights and fix the top three issues
Go to pagespeed.web.dev. Enter your landing page URL and run the Mobile analysis. Google provides an Opportunities list with estimated time savings for each fix. Prioritise: eliminate render-blocking resources (typically JavaScript and CSS that pause page rendering), properly size and compress images (the most common culprit for slow LCP), and defer offscreen images with lazy loading. Addressing the top three opportunities alone typically moves an LCP from 4+ seconds to under 2.5 seconds.
-
Match the landing page headline to the ad's primary message
The first thing a user sees when they land must confirm they are in the right place. If your ad headline is "Google Ads Management Dubai" then your landing page H1 should be something like "Google Ads Management for Dubai Businesses" or "Dubai's Specialist Google Ads Management Agency." The psychological reassurance of message match also improves conversion rate independently of its Quality Score impact - both benefits accrue from the same change.
-
Create dedicated landing pages for high-spend keyword themes
A single homepage or generic services page cannot provide Above Average Landing Page Experience for keywords spanning different service areas, locations, or audiences. If you are spending significant budget on keywords across five different service categories, each category deserves a dedicated landing page with content, headlines, and social proof specifically relevant to that category's search intent. This is the highest-ROI structural investment for accounts where Landing Page Experience is the primary Quality Score drag.
-
Remove intrusive pop-ups and interstitials from paid landing pages
Any pop-up or interstitial that appears immediately when a user lands from a Google Ad - before they can read the page content - triggers a negative Landing Page Experience signal. This includes newsletter pop-ups, chat widgets that cover content on mobile, and cookie consent banners that obscure the page. Delay pop-ups to appear only after 30 seconds or when the user shows exit intent. Cookie consent banners should be configured to appear at the bottom of the screen rather than as full-page overlays.
-
Check and fix Core Web Vitals in Google Search Console
In Google Search Console, go to Experience, then Core Web Vitals. This report shows LCP, CLS (Cumulative Layout Shift), and INP (Interaction to Next Paint) performance for your actual pages as Google measures them. Poor ratings here directly correlate with Below Average Landing Page Experience in Google Ads. Fix poor-rated pages before assuming the issue is ad copy or keyword structure.
Every improvement to Landing Page Experience that raises Quality Score - faster load speed, better message match, clearer conversion path, more specific and relevant content - also directly improves your conversion rate. Unlike Expected CTR or Ad Relevance improvements which primarily affect click cost and volume, Landing Page Experience improvements improve both the cost side (lower CPC through better Quality Score) and the revenue side (higher conversion rate from better page experience) simultaneously. It is the highest-leverage single area of improvement in most accounts.
How to Find and Fix Low Quality Scores in Your Account
Knowing what Quality Score is and how it works does not help unless you can systematically identify which keywords are dragging your account down and in which direction. The audit process below takes 20 to 30 minutes for most accounts and produces a prioritised fix list ordered by financial impact.
Step 1: Add Quality Score Columns to Your Keywords Report
In Google Ads, go to Keywords in the left navigation. Click the Columns button (pencil icon at the top right of the report). Under Add Columns, expand the Quality Score section. Add all six columns: Quality Score, Quality Score (hist.), Expected CTR, Landing Page Exp., Ad Relevance, and Quality Score Status. Click Apply. You can now see the current score, each component rating, and the historical score for every keyword in your account.
Step 2: Filter by Quality Score Below Average and Sort by Cost
Click the filter icon and add a filter: Quality Score, Less than, 6. This shows every keyword scoring 5 or below. Now sort by Cost (descending). The keywords at the top of this filtered, sorted list are your highest-priority fixes - the highest-spend keywords with the lowest Quality Scores, where the CPC premium is costing you the most money right now.
Identifies the keywords where low Quality Score is costing you the most money. These are your fix priorities - address the top 20 by spend before moving to lower-spend keywords.
For each high-priority keyword, note which of the three component columns shows "Below Average." This tells you exactly where to focus: Expected CTR = fix ad copy, Ad Relevance = fix ad group structure or ad copy, Landing Page Experience = fix the page.
Keywords that all point to the same landing page share Landing Page Experience issues. Keywords in the same ad group share Ad Relevance and Expected CTR challenges. Group your fix actions by root cause rather than addressing keywords individually - fixing the landing page fixes all keywords pointing to it at once.
Landing page fixes take the longest to implement but affect the most keywords simultaneously. Ad copy fixes are faster and show results within 1 to 2 weeks. Ad group restructuring is the slowest to show Quality Score impact because it resets historical data.
Quality Score updates are not instant. After making changes, the score needs time to reflect improved performance as new data accumulates. Do not make further changes within 2 weeks of a fix or you lose the ability to measure the impact of the first change.
The Keywords to Pause Rather Than Fix
Not every low Quality Score keyword is worth fixing. Some keywords are structurally unable to achieve high Quality Scores regardless of how much effort you invest in them. The most common examples:
- Competitor brand keywords with Quality Score 1 to 3 Competitor keywords almost always have low Ad Relevance because your ad and landing page legitimately cannot claim to be the competitor's product. Unless you have the budget and creative to build a dedicated competitor comparison strategy with its own ad copy and landing page, these keywords are persistent low-QS drags. Consider whether the conversion economics justify the CPC premium before investing in a competitor keyword strategy
- Overly broad informational keywords in commercial campaigns Keywords like "what is google ads" or "how does PPC work" in a commercial campaign will always have Below Average Ad Relevance because the user intent (learning) does not match the commercial campaign goal (generating leads). Pause these and add them as negative keywords to prevent your commercial campaign from wasting budget on informational queries with no conversion intent
- Keywords generating fewer than 1,000 impressions over 90 days Low-volume keywords have insufficient data for Google to generate a reliable Quality Score. The score shown may be 3 but based on only 50 impressions - it is a statistical sample too small to act on. Focus your Quality Score improvement efforts on keywords with enough impression volume that the score is a meaningful signal rather than noise
Quality Score in 2026: How It Interacts With Smart Bidding
A common misconception since Smart Bidding became the dominant bidding approach is that Quality Score no longer matters because the algorithm handles everything. This is incorrect. Smart Bidding does not replace the Quality Score mechanism in the Ad Rank formula. It means Google bids more intelligently in auctions where your Quality Score gives you a competitive advantage, and bids less on auctions where a low Quality Score makes winning too expensive.
The practical consequence is that low Quality Scores reduce Smart Bidding's ability to find you efficient conversions. If your Target CPA is $50 and your keywords have Quality Scores of 3, Google's algorithm calculates that the CPC premium you are paying for those queries makes the CPA target unachievable. It either bids very low (reducing volume) or does not bid at all. The account appears to be under-delivering relative to budget, and the root cause is not the bidding strategy - it is the Quality Score creating a floor on what efficient acquisition can cost.
The most useful framing for Quality Score in a Smart Bidding era is as a diagnostic indicator rather than a primary KPI. A keyword with Quality Score 3 is telling you something is structurally wrong with the keyword-ad-page journey for that query. It is worth investigating regardless of whether that keyword is converting, because if it is converting at a low Quality Score it would convert more efficiently with a higher one. If it is not converting, the Quality Score components tell you which part of the journey is broken. See the Google Ads account audit guide for the full Quality Score audit process as part of a complete account review.
How Account Structure Affects Quality Score at Scale
Individual keyword fixes address symptoms. Account structure determines whether high Quality Scores are sustainable at scale. The structural decisions you make about how campaigns, ad groups, and keywords are organised either create the conditions for consistently high Quality Scores or consistently make them difficult to achieve regardless of how much effort you invest in ad copy and landing pages.
The Single Keyword Ad Group (SKAG) Question
Single Keyword Ad Groups (SKAGs) - where each ad group contains only one keyword - were a popular approach to maximising Ad Relevance through total control over the keyword-to-ad match. In 2026 with broad match and Smart Bidding, SKAGs have become significantly less practical. A SKAG for an exact match keyword may get very few impressions if the query volume is low, producing a meaningless Quality Score. And with broad match keywords triggering hundreds of different query variants, a SKAG no longer guarantees high Ad Relevance because the single keyword triggers diverse queries.
The 2026 best practice is tight themed ad groups rather than true SKAGs - ad groups of 3 to 10 closely related keywords that share the same user intent, so a single well-crafted RSA can serve all of them with genuine relevance. This captures the Ad Relevance benefit of tight structuring without the management overhead and data dilution problems of true single-keyword groups.
Keyword Match Types and Quality Score
Match type affects Quality Score in ways that are not always obvious. Exact match keywords tend to have higher Quality Scores because the triggering query is always the keyword itself - there is no variance in what triggers the ad. Phrase and broad match keywords trigger a range of queries, some of which may be poorly matched to your ad copy, pulling the average Quality Score lower. This does not mean broad match should be avoided - it means the Search Terms report for broad match keywords needs regular negative keyword management to prevent low-relevance queries from accumulating impressions and dragging Quality Score down.
✅ Structure That Supports High Quality Score
- 3 to 10 closely related keywords per ad group with the same search intent
- Dedicated ad groups for branded, non-branded, and competitor terms separately
- One RSA per ad group with 15 headlines all genuinely relevant to the group theme
- Dedicated landing pages per campaign theme with message-matched headlines
- Regular negative keyword reviews on broad match groups to block irrelevant queries
- New high-priority keywords in dedicated ad groups rather than added to existing ones
❌ Structure That Drags Quality Score Down
- Ad groups with 30+ keywords spanning multiple different user intents
- Branded, non-branded, and competitor keywords in the same ad group
- All campaigns pointing to the same homepage regardless of keyword theme
- Generic RSA headlines reused across multiple different ad groups
- Broad match keywords without negative keyword lists creating irrelevant triggers
- Dormant keywords with long histories of low CTR remaining active in the account
The Quality Score Quick-Win Action Plan
Based on the components covered in this guide, here is the ordered action plan for improving Quality Score across a typical Google Ads account. Each action is ordered by estimated time to implement and financial impact. Work through them in sequence - each builds on the previous.
Week 1: Filter keywords by QS below 6, sort by cost, and identify the top 20 keywords where CPC penalties are highest. Note the Below Average component for each. For any keyword with Below Average Landing Page Experience pointing to a slow page: run PageSpeed Insights and fix the top three speed issues. Week 1-2: For keywords with Below Average Expected CTR, review RSA asset performance and replace all Low-rated headlines. Add all available ad assets (minimum 4 sitelinks, 4 callouts, 2 structured snippets) to every campaign missing them. Week 2-3: For keywords with Below Average Ad Relevance, identify oversized ad groups and split by intent theme. Rewrite ad copy for each new tighter group to directly address the keyword theme. Week 3-4: For high-spend keywords with persistently low QS despite ad copy fixes, create dedicated landing pages that match the ad's primary message. Week 4+: Re-evaluate Quality Scores after 4 weeks. Pause keywords with QS of 1 or 2 that have not improved despite fixes - these are structurally misaligned and should be replaced with tighter variants.
For a complete account-level quality assessment that includes Quality Score as part of the broader performance review, the 30-minute Google Ads account audit guide covers all six major audit areas including Quality Score, conversion tracking, search term waste, bidding strategy, campaign structure, and Performance Max. You can also run an automated Quality Score check through AdAudit at auditroger.com, which identifies low-QS keywords, flags the Below Average components, and generates a prioritised fix list in minutes.
