If you’re running Google Ads and your cost per click feels too high, or your ads are showing in positions lower than your competitors despite a higher bid, the likely culprit is Quality Score. It is one of the least understood but most financially significant metrics in the platform. Improving it can cut what you pay per click by 20 to 50 percent — without changing your bid at all. This guide explains what Quality Score is, how it works, and the specific changes that move the needle. It is the companion piece to the JSB Media Plan – SEM/Paid Ads/Google Ads pillar and assumes you’ve already built a basic campaign using the Google Ads first campaign guide.

What Quality Score Is (and What It Isn’t)

Quality Score is a 1–10 rating Google assigns to each of your keywords. It is Google’s estimate of how relevant and useful your ad and landing page are to someone searching for that keyword. A 10 means Google considers your ad highly relevant; a 1 means it’s a poor match for the search.

Quality Score is not a direct ranking factor in the sense that Google doesn’t rank your ad purely by it. What actually determines your ad position is your Ad Rank, which is calculated roughly as: your bid × your Quality Score × the expected impact of your ad formats. The practical result is that a higher Quality Score lets you pay less per click for the same position — or claim a better position than a competitor who bids more but has a lower Quality Score. A 7/10 ad can outrank and outcheap a 3/10 ad from a competitor bidding twice as much.

The Three Components of Quality Score

Google builds Quality Score from three sub-metrics, each rated “Above average,” “Average,” or “Below average.” You can see these in your Google Ads interface by checking the Quality Score columns. Fix the components rated “Below average” first — that’s where the biggest gains are.

1. Expected Click-Through Rate (CTR)

This is Google’s prediction of how often your ad will be clicked when it appears for a given search, compared to other ads in the same auction. It is based on historical performance of your ad and similar ads. A “Below average” expected CTR means Google thinks your ad is less compelling or relevant than competing ads for that keyword.

2. Ad Relevance

This measures how closely your ad copy matches the intent of the search. If someone searches “emergency roof repair near me” and your ad headline says “Quality Roofing Services — Free Estimates,” the relevance signal is weaker than an ad that says “Emergency Roof Repair — Same-Day Response.” Google is asking: does this ad answer what the person was looking for?

3. Landing Page Experience

Google evaluates the page you send clicks to — specifically whether it is relevant to the ad and keyword, whether it loads quickly, whether it is mobile-friendly, and whether it provides a good experience. A landing page that buries the offer three scrolls down, loads in eight seconds, or sends clicks to a generic homepage will score poorly here. This component is within your full control and often the most impactful to fix.

How to Check Your Quality Score

In Google Ads:

  1. Navigate to Campaigns → Keywords.
  2. Click the Columns button (the icon with stacked lines) and choose Modify columns.
  3. Under Quality Score, add: Quality Score, Expected CTR, Ad Relevance, and Landing Page Experience.
  4. Apply the changes. You’ll now see a score for every keyword, plus the sub-component ratings that tell you exactly what to fix.

Keywords with fewer than a few hundred impressions may show “—” instead of a score — Google needs sufficient data. Focus first on your highest-volume, highest-spend keywords with low scores.

Fix #1: Improve Expected CTR With Better Headlines

If Expected CTR is rated “Below average,” your ads are not compelling people to click. Common causes and fixes:

  • Your headline is generic. “Professional Services in [City]” competes with 50 identical ads. Mirror the specific language of the search: if the keyword is “affordable divorce attorney Tampa,” the headline should say “Affordable Divorce Attorney – Tampa FL.”
  • Your differentiator is buried or missing. State your most compelling advantage in headline one or two — same-day service, a guarantee, a specific price, years of experience, or a credential that matters to buyers.
  • You’re not using all available extensions. Sitelinks, callouts, structured snippets, and call extensions make your ad physically larger and add more reasons to click. Ads without extensions are consistently outperformed by ads with them, at zero additional cost per extension.
  • Your descriptions are filler. “We offer high-quality services at competitive prices” says nothing. “Licensed since 2009 · 500+ five-star reviews · Same-day availability” says something. Specifics convert; generics do not.

Fix #2: Improve Ad Relevance With Tighter Ad Groups

Ad Relevance suffers when one ad group contains keywords that are too different from each other. If your ad group for “plumbing services” contains keywords like “burst pipe repair,” “drain cleaning,” and “water heater installation,” no single ad can be highly relevant to all three searches at once. The fix is to split them:

  • Create one ad group for burst pipe emergencies, with ads specifically about emergency pipe repair.
  • Create a separate ad group for drain cleaning, with ads that mention drains.
  • Create a third for water heaters, with ads that mention water heater brands, installation, and repair.

This approach — sometimes called a tightly-themed or single-keyword-per-group structure — is more work to set up but consistently produces higher Quality Scores, lower CPCs, and better conversion rates. Google rewards ads that closely match what was searched. The more tightly you can match, the better.

Also check that your keywords and ads use the same language your customers use. If customers search for “hot water heater repair” but your ad says “water heater service,” there’s a relevance gap even though they mean the same thing.

Fix #3: Improve Landing Page Experience

Landing Page Experience is often where the biggest Quality Score gains live, because most small business ads send traffic to their generic homepage. A homepage optimized for everything is optimized for nothing.

Create a dedicated landing page for each major ad group or campaign. The page should:

  • Match the headline and offer in the ad exactly. If the ad promises “Free Same-Day Estimate,” those words should appear on the page, above the fold, without scrolling.
  • Load in under three seconds. Page speed is a direct input to Landing Page Experience. Test your page at pagespeed.web.dev and fix the highest-impact issues. For WordPress users, caching plugins and properly sized images cover most of it — see the WordPress SEO guide.
  • Be fully functional on mobile. Google uses mobile performance to assess landing page experience, even for desktop searches.
  • Have one clear call to action. A landing page asking visitors to call, fill a form, read a blog, follow on social, and watch a video simultaneously converts no one.
  • Include trust signals: reviews, ratings, certifications, logos of clients or partners, or a guarantee statement. Trust reduces hesitation, and higher conversion rates signal to Google that your landing page is delivering value.

Quality Score Myths Worth Debunking

  • Myth: Quality Score is calculated in real time. It is updated periodically, not instantly. Changes you make today may take days or weeks to reflect in your score. This is normal — do not undo good changes just because the score hasn’t moved in 48 hours.
  • Myth: Pausing or deleting low-Quality Score keywords hurts you. Removing a keyword removes its score from your account. It does not negatively affect the scores of your remaining keywords.
  • Myth: Bidding higher improves your Quality Score. Bid amount is not an input into Quality Score. Only CTR, ad relevance, and landing page experience are.
  • Myth: Quality Score should be 10 for every keyword. A score of 7 or 8 on competitive keywords is strong. Chasing a perfect 10 on every keyword is not a productive use of your time. Focus on moving 3s and 4s to 6s and 7s first — that’s where the financial impact is largest.

How Long Does It Take to See Improvement?

Quality Score reflects historical performance data, so improvements accumulate over time. After making meaningful changes to your ads and landing pages:

  • One to two weeks: Google begins collecting impression data on the updated ads. You may see small movements.
  • Three to four weeks: If your CTR and landing page engagement have improved, scores typically begin moving upward.
  • Six to eight weeks: Meaningful score improvements are usually visible on your highest-volume keywords.

The most common reason Quality Score doesn’t improve is that the changes weren’t significant enough — rewording one headline is not the same as rebuilding an ad group with tighter theming and a dedicated landing page. The businesses that see the biggest drops in CPC make structural changes, not cosmetic tweaks.

Connecting Quality Score to Your Broader Paid Strategy

A high Quality Score is not the goal — profitable conversions are. Quality Score is a leading indicator that your ads are relevant, which leads to lower CPCs, which means more conversions for the same budget. Track it as a health metric, not a vanity number.

Once your Quality Scores are in the 7–10 range on your core keywords and your conversion tracking is working cleanly, you have the foundation to responsibly expand: add more keywords, test Performance Max, or increase budgets on proven campaigns. The data you gain from a well-optimized campaign also feeds your content marketing — the exact search terms that convert into customers are the topics your organic content should target next. That is how each pillar of the JSB Media Plan makes the others more effective.
