Google Ads Quality Score is a keyword-level diagnostic that rates the quality and relevance of your ads and landing pages on a 1-10 scale, directly influencing how much you pay per click and where your ads appear. In 2026, Quality Score still determines whether you pay a premium or a discount in every single auction. This guide breaks down all three Quality Score components, how to diagnose problems at the keyword and account level, the exact optimization priority order that moves the needle on CPC and conversion volume, and where most advertisers waste their time chasing the wrong fixes. Whether you manage Google Ads yourself or work with an agency, understanding these factors is essential to running profitable campaigns.
Quality Score is Google's 1-10 rating assigned to each keyword in your account, based on the expected quality of your ads and landing pages when that keyword triggers an auction. It is not a vanity metric. Quality Score directly determines your Ad Rank alongside your bid, which means it controls both your position and your actual cost per click.
A keyword with a Quality Score of 8 will often pay significantly less per click than a competitor bidding on the same term with a Quality Score of 5, even if both advertisers set the same max CPC. Google rewards relevance. That reward compounds across thousands of keywords and millions of auctions.
Every Quality Score is built from three component ratings, each graded as "Below Average," "Average," or "Above Average":
Expected CTR measures how likely your ad is to be clicked when shown for that keyword, based on historical performance and normalized against position.
Ad Relevance measures how closely your ad copy matches the intent behind the keyword.
Landing Page Experience measures whether your landing page delivers a relevant, fast, and useful experience after the click.
Each component contributes to the overall 1-10 score, but they are not weighted equally. Expected CTR and landing page experience tend to carry more weight than ad relevance alone.
Google uses Quality Score (along with other real-time auction signals) to calculate your Ad Rank. The formula simplified: Ad Rank = Bid x Quality Score (plus auction-time factors). A higher Quality Score means you need a lower bid to achieve the same position.
In practice, this means advertisers with strong Quality Scores can dominate auctions while paying less per click than competitors with weaker scores. Over time, even a one-point improvement across a large keyword set can reduce average CPC noticeably, freeing budget for more volume.
Misconception: Performance Max and AI Max have made Quality Score irrelevant. Quality Score still applies to Search campaigns. Performance Max uses its own auction dynamics, but the moment you run keyword-targeted Search ads, Quality Score is in play.
Misconception: Smart Bidding optimizes Quality Score for you. Smart Bidding adjusts bids based on conversion probability. It does not rewrite your ad copy, restructure your ad groups, or fix your landing pages. Quality Score improvement requires deliberate structural and creative work that bidding algorithms do not perform.
Misconception: Quality Score is updated in real time. The visible 1-10 score updates periodically, not in real time. Google uses real-time signals in the auction that go beyond the reported score, but the diagnostic you see in your account reflects historical performance over time.
Expected CTR is the single most impactful Quality Score component for most accounts. It measures Google's prediction of whether your ad will be clicked when shown for a given keyword, normalized for ad position. A "Below Average" rating here is the most common Quality Score killer.
Google calculates expected CTR by comparing your ad's historical click-through rate for that keyword against other advertisers competing on the same term, adjusted for position. Your actual CTR at position 1 is compared against other position 1 performances, not against ads showing in position 4.
Key factors include your headline relevance, the presence of the search term or close variants in your ad copy, your account's historical CTR patterns, and ad extensions (now called assets) that increase real estate and engagement.
Google factors in account-level and campaign-level historical performance when scoring expected CTR, especially for newer keywords without much data. An account with a long track record of high CTRs will see new keywords benefit from that history. Conversely, accounts with chronically low CTRs face an uphill battle when launching new keywords.
This is one reason why groas performs a full hands-on audit of your entire Google Ads account during onboarding. Account-level historical signals matter, and a dedicated human account manager identifies patterns in historical performance that inform which keywords need structural fixes versus which simply need better creative. The AI agents at groas then continuously test and optimize ad copy around the clock, something a human team checking in a few times per week simply cannot replicate.
The fastest path to improving expected CTR:
1. Front-load keywords in headlines. Responsive Search Ads (RSAs) with your target keyword in at least 2-3 headline variations perform better on expected CTR. The keyword does not need to be exact-match in the headline, but close alignment matters.
2. Test aggressively, but test smart. Run RSAs with diverse headline and description combinations. Google will surface winning combinations, but only if you give it meaningfully different options. Avoid writing 15 headlines that all say the same thing with slight word swaps.
3. Use all available ad assets. Sitelinks, callouts, structured snippets, and image assets all increase your ad's visual footprint and CTR. Google factors asset performance into expected CTR calculations.
4. Pause chronic underperformers. Keywords with persistent "Below Average" expected CTR drag down account-level signals. Either fix them or pause them.
Pinning headlines and descriptions in RSAs restricts which combinations Google can serve. Heavy pinning (pinning all positions) essentially turns your RSA into an expanded text ad, which limits Google's ability to optimize combinations for different auction contexts.
The best practice in 2026: pin your most important value proposition to headline position 1, leave headline positions 2 and 3 unpinned, and provide at least 8-10 unique headlines. This balances message control with enough flexibility for Google to optimize CTR.
Ad relevance measures whether your ad copy matches the intent and language of the triggering keyword. It is the most misunderstood Quality Score component because a "Below Average" rating does not necessarily mean your ad is bad. It means there is a structural disconnect between your keywords and your ad copy.
Ad relevance specifically evaluates the semantic connection between your keyword and your ad text. It does not measure landing page content, CTR, or conversion rate. You can have excellent CTR and landing page scores but still show "Below Average" ad relevance if the keyword and ad copy are misaligned.
This typically happens when ad groups contain keywords that span multiple intents, and the ad copy can only address one of them.
With broad match now handling most of the matching work in modern Google Ads accounts, a single keyword can trigger for a wide range of search queries. Ad relevance is scored against the keyword itself, not the search query. So even when broad match triggers your keyword for a tangentially related query, the ad relevance score reflects how well your ad matches the keyword you added to your ad group.
This means ad group structure matters more than ever. Grouping keywords by tight intent clusters and writing ad copy that speaks directly to that cluster is the primary lever for ad relevance.
Single keyword ad groups (SKAGs) are largely obsolete in 2026 due to close variant matching, broad match expansion, and RSA dynamics. Instead, aim for intent-based ad groups: 5-15 keywords per group, all sharing the same core intent, with RSA copy written directly to that intent.
For example, instead of creating separate ad groups for "accounting software pricing," "accounting software cost," and "how much does accounting software cost," group them together. They share the same intent. Your RSA headlines should address pricing, cost, and value directly.
AI Max for Search campaigns can automatically create ads and match to queries outside your keyword list. In these configurations, traditional ad relevance scoring becomes less directly controllable because Google is generating and matching more dynamically.
If you use AI Max, monitor which search themes are triggering your ads and whether the auto-generated creative aligns with your value propositions. For accounts where brand messaging precision matters, maintaining manually structured campaigns alongside any AI Max experiments gives you a controllable baseline. This is exactly the kind of cross-campaign strategic decision that an agency failing to monitor properly would miss, and where having dedicated human oversight makes a real difference.
Landing page experience evaluates what happens after the click. Google assesses whether your landing page is relevant to the keyword, loads quickly, works well on mobile, and provides a useful experience. A "Below Average" landing page experience rating is one of the hardest components to fix because it often requires changes outside of Google Ads itself.
Google evaluates landing pages on several dimensions: content relevance (does the page match the keyword and ad promise?), load speed (both on desktop and mobile), mobile usability (responsive design, tap targets, readability), navigation and transparency (can users easily find what they need?), and trustworthiness (privacy policy, business information, secure connection).
Core Web Vitals remain a factor in 2026. The three metrics that matter most: Largest Contentful Paint (LCP) should be under 2.5 seconds, Interaction to Next Paint (INP) should be under 200 milliseconds, and Cumulative Layout Shift (CLS) should be under 0.1. Run Google's PageSpeed Insights on your landing pages and address any flagged issues.
Mobile experience is weighted heavily. More than half of Google Search traffic comes from mobile devices, and Google's Quality Score assessment reflects mobile performance. If your page loads fast on desktop but slowly on mobile, your landing page experience score will suffer.
Start with keywords that show "Below Average" landing page experience. For each, check:
Speed: Run PageSpeed Insights and address any Core Web Vital failures. Relevance: Does the landing page headline match the ad headline and keyword intent? Generic pages that serve every keyword will score poorly. Mobile experience: Test on an actual device, not just responsive preview. Trust signals: HTTPS, visible contact information, clear privacy policy.
Sending all traffic to the homepage. Your homepage is designed for browsing, not for answering a specific keyword query. Dedicated landing pages aligned to keyword intent consistently score better.
Slow third-party scripts. Chat widgets, analytics tags, and video embeds that block page rendering destroy your LCP score. Audit and defer non-critical scripts.
Thin content. Pages with minimal text content and heavy imagery provide Google's crawlers too little to evaluate for relevance. Ensure your landing page has substantive, keyword-relevant content.
Interstitials on mobile. Pop-ups that cover the main content on mobile devices directly hurt your landing page experience score.
Diagnosing Quality Score issues starts with knowing where to look and what the component ratings actually tell you. Many advertisers see a Quality Score of 5 and start guessing at fixes. A structured diagnosis takes the guesswork out.
Navigate to the Keywords tab in any Search campaign. Add the following columns: Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience. You can also add historical versions of these columns (Quality Score (hist.)) to see how scores have changed over time.
For account-level patterns, segment by campaign or ad group and look for clusters of keywords with "Below Average" ratings in the same component. This reveals whether you have a systemic issue (like slow landing pages across the account) or isolated problems in specific ad groups.
Below Average is the only rating that actively hurts you. Average is neutral. Above Average gives you a competitive advantage in auctions.
Focus remediation efforts on keywords with any "Below Average" component. Moving from "Below Average" to "Average" on any component typically has a larger impact on your overall Quality Score than moving from "Average" to "Above Average."
Quality Score is reported at the keyword level, but patterns often emerge at the account level. If landing page experience is "Below Average" across dozens of keywords pointing to the same page, the fix is one page, not dozens of keyword-level adjustments. If expected CTR is low across an entire campaign, the issue is likely ad copy or account structure, not individual keywords.
Not all Quality Score improvements are created equal. There is a clear priority order that maximizes ROI on your optimization time.
Priority 1: Fix "Below Average" landing page experience. This typically affects the most keywords simultaneously and has the largest per-keyword CPC impact. One landing page fix can improve scores across an entire ad group or campaign.
Priority 2: Improve "Below Average" expected CTR. Ad copy testing, asset optimization, and pausing underperforming keywords address this component. The impact is significant but requires ongoing iteration.
Priority 3: Address "Below Average" ad relevance. Restructure ad groups by intent and align ad copy to keyword clusters. This is the lowest-leverage fix individually, but combined with the above, it rounds out your Quality Score improvement.
Ignore keywords already at "Average" or above. The marginal gain from pushing "Average" to "Above Average" is small compared to fixing "Below Average" components elsewhere. Spend your time where the gap is largest.
Quality Score optimization makes sense when your CPCs are higher than they should be for your conversion rates, or when you are losing impression share to rank. But if your account's primary problem is targeting the wrong keywords, bidding on unprofitable terms, or running a flawed account structure, fixing Quality Score will not save you. Fix the strategic foundation first.
This is where the complexity of Quality Score optimization collides with the reality of time and attention. An account with hundreds or thousands of keywords, each with three component scores to monitor, is too much for a human team checking in a few hours per week. Agencies typically focus on the highest-spend keywords and ignore the long tail. Freelancers prioritize whatever is loudest.
groas approaches this differently. AI agents monitor Quality Score components across every keyword in your account continuously, flagging degradation in any component and executing fixes (ad copy tests, asset rotations, landing page recommendations) without waiting for a weekly check-in. Your dedicated human account manager at groas reviews these changes, ensures they align with your business strategy, and makes the cross-campaign decisions that require human judgment, like whether to restructure ad groups or recommend landing page changes to your team. This combination of 24/7 AI execution and human strategic oversight is what makes the difference between incremental Quality Score improvement and systematic, account-wide optimization.
Quality Score benchmarks vary meaningfully by industry and campaign type. Branded keywords typically score 8-10 because ad relevance and expected CTR are naturally high when someone searches your brand name. Non-branded keywords in competitive industries like legal, insurance, and finance often average 5-6 without active optimization.
Ecommerce Shopping campaigns do not use traditional Quality Score (Shopping uses product data quality instead), but Search campaigns supporting ecommerce follow standard Quality Score dynamics.
B2B and SaaS campaigns often struggle with landing page experience because B2B landing pages tend to be gated, slow-loading, or thin on content. Addressing these issues typically yields the biggest Quality Score gains in B2B accounts.
Local service campaigns (dentists, law firms, home services) usually see strong ad relevance scores when campaigns are properly geo-targeted and ad copy is location-specific, but expected CTR can lag if ad assets are underutilized.
A reasonable target for non-branded keywords in most industries is 7 or above. Keywords consistently scoring below 5 deserve either structural remediation or removal from the account.
Quality Score in 2026 is not a mystery, but it is a system that rewards consistent, structured effort across creative, landing pages, and account architecture simultaneously. Most teams struggle not because they do not understand Quality Score, but because they lack the bandwidth to monitor and optimize all three components across every keyword, every day. If your team is stretched thin, or your agency is only reviewing Quality Score during monthly reports, you are leaving CPC savings and auction competitiveness on the table. groas combines AI agents that optimize continuously with a dedicated human account manager who owns your strategy, giving you systematic Quality Score improvement without adding a single task to your plate. That is the difference between knowing what to fix and actually fixing it at scale.
A good Quality Score for non-branded keywords is 7 or above. Branded keywords typically score 8-10 naturally due to high ad relevance and expected CTR. Keywords scoring below 5 on a consistent basis are actively hurting your CPC and auction position, and should be either restructured or removed. The benchmark varies by industry: competitive verticals like legal and insurance often average 5-6 without active optimization, while well-managed accounts in less competitive spaces can reach 7-8 on most keywords.
Yes, but only for Search campaigns. Performance Max uses its own auction dynamics and does not display traditional Quality Score. However, any keyword-targeted Search campaign still relies on Quality Score to determine CPC and Ad Rank. If you run Search campaigns alongside Performance Max, Quality Score optimization remains essential. AI Max for Search introduces more dynamic ad creation, but keyword-level Quality Score still applies to the keywords you target.
Quality Score updates are not instant. Google recalculates the visible 1-10 score periodically based on accumulated performance data. Landing page experience changes can take days to weeks to reflect in your score after implementation. Expected CTR improvements from new ad copy may take a few hundred impressions before Google has enough data to update the rating. Plan for 2-4 weeks of consistent effort before seeing meaningful movement in your reported scores.
No. Smart Bidding adjusts your bids based on conversion probability signals, but it does not change your ad copy, restructure your ad groups, or improve your landing pages. These are the three areas that determine Quality Score. Smart Bidding and Quality Score optimization are complementary but separate efforts. You need to actively manage creative, structure, and landing page quality independently of your bidding strategy.
Start by ensuring your target keyword appears in at least 2-3 RSA headline variations. Then test genuinely diverse headlines rather than minor word swaps. Add all available ad assets (sitelinks, callouts, structured snippets, images) to increase your ad's footprint and engagement rate. Finally, pause keywords with persistent Below Average expected CTR that are dragging down account-level signals. These steps, executed together, typically produce the fastest CTR improvement.
SKAGs are largely obsolete in 2026. Close variant matching, broad match expansion, and RSA dynamics mean a single keyword can trigger for a wide range of queries regardless of ad group structure. Instead, group 5-15 keywords by shared intent into tight ad groups and write RSA copy that speaks directly to that intent. This approach delivers strong ad relevance scores without the management overhead and fragmentation of SKAGs.
groas combines AI agents that monitor Quality Score components across every keyword in your account 24/7 with a dedicated human account manager who oversees strategy. Unlike agencies that review Quality Score during monthly reports or freelancers who check in a few times per week, groas catches degradation in any component immediately and executes fixes, including ad copy tests, asset rotations, and landing page recommendations, without waiting for a scheduled review. This means systematic, account-wide Quality Score improvement rather than occasional spot fixes.
Yes. Landing page load speed, measured through Core Web Vitals like Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS), directly influences your landing page experience rating. Google weights mobile performance especially heavily. A page that loads fast on desktop but slowly on mobile will still receive a poor landing page experience score. Run Google PageSpeed Insights on every landing page you send Google Ads traffic to.
It depends on your growth goals. If you are profitable but paying higher CPCs than necessary due to Quality Score issues, fixing those issues frees up budget to capture more volume at the same spend level. However, if your account has strategic problems like poor targeting or flawed structure, fix those first. groas evaluates both strategic health and Quality Score systematically during its full account audit, so your dedicated account manager can tell you exactly where optimization effort will generate the highest return.
Expected CTR and landing page experience carry more weight than ad relevance in the overall Quality Score calculation. Fixing a Below Average landing page experience rating typically has the largest CPC impact because it often affects many keywords pointing to the same page simultaneously. Expected CTR is the second priority, as it requires ongoing ad copy testing. Ad relevance is the lowest-leverage individual fix but still matters when combined with the other two components.
