It's called Quality Score, and if you've read anything else on this site, you've met it already: it's the mechanism behind why your website sets your ad costs, why campaign structure decides what a budget buys, and part of why your own searches often show nothing. This page is the reference those arguments stand on — what the score actually is, how to read yours tonight, and what moves each piece of it.
What it is, plainly
Quality Score is a 1–10 rating Google assigns per keyword, built from three graded components:
- Expected click-through rate — how likely someone is to click your ad when it shows for this keyword
- Ad relevance — how closely your ad's text matches what the person searched
- Landing page experience — whether the page the click lands on is fast, relevant, and usable
Each component is graded Above average, Average, or Below average against everyone else bidding on that keyword. The 1–10 number is the summary; the three grades underneath are the diagnosis.
One honest caveat before the mechanics: the visible score is a diagnostic snapshot, not the literal input to each auction — at auction time Google uses more granular, real-time versions of the same signals. But the snapshot is what you can see, the components are what you can act on, and the direction is the same: better components, cheaper clicks.
Why it's money, not a vanity metric
The auction that decides whether your ad shows — and what a click costs — ranks advertisers by (roughly) bid × quality. Hold that arithmetic still for a second, because it's the whole point:
If your quality signals are weak and a competitor's are strong, you need a proportionally higher bid to buy the same position. In the simplified version of the math, an account scoring 5 has to bid about 60% more than an account scoring 8 to stand in the same spot. Same search, same pet owner, same position on the page — one practice pays a premium for every click, indefinitely, because of the grade.
That's why the website pillar calls a slow site a standing surcharge on every ad click you buy. It isn't a metaphor. The surcharge has a name, and it's this one.

Quality Score is hidden by default. To see it:
- Log into Google Ads → Campaigns → Keywords (the keyword-level view, not campaigns or ad groups).
- Click the columns icon → Modify columns → Quality Score section.
- Add four columns: Quality Score, Exp. CTR, Ad relevance, and Landing page exp. Apply.
Now read what you're looking at. A dash (—) instead of a number isn't an error and isn't zero — it means the keyword hasn't had enough recent traffic on that exact term for Google to grade it. Common in a small account; ignore those rows and read the graded ones.
What you want is not "every keyword at 10." You want to know which component is dragging which keywords, because each component has a different fix — and they map to different parts of how the account and website were built.
Reading the three columns
Expected CTR: Below average
Google is predicting people won't click your ad for this search. In a vet account, the usual cause is a keyword sitting in the wrong home — "emergency vet" and "puppy vaccinations" sharing one ad group, served by one generic ad that speaks urgently to neither. The searcher with the blocked cat at 11pm doesn't click the ad that leads with wellness plans.
What moves it: tighter keyword-to-ad grouping and ad copy written for the specific search. This is a structure problem before it's a copy problem — the architecture argument in one column.
Ad relevance: Below average
The ad's text doesn't match the search closely enough — the keyword's language doesn't appear in what the searcher reads. Same root cause as above, seen from the ad's side: catch-all campaigns produce catch-all ads, and Google grades them as exactly that.
What moves it: service-level campaigns where the ad can say the thing the person searched. An ad group for dental keywords whose ads say "dental" is not sophisticated. It's just correct — and the account gets paid for being correct on every click.
Landing page experience: Below average
The click lands somewhere slow, generic, or off-topic. This is the component your website controls — and the one most vet accounts quietly bleed on, because the ads point at a homepage that loads in eight seconds and mentions the searched-for service in a dropdown menu.
What moves it: speed, and a page that's actually about the search. The emergency click lands on the emergency page; the page loads before the panic wears off; the phone number is at the top. This entire component is what the website exists to do.
What not to do with the number
Don't chase the score itself. Quality Score is a diagnostic, not a KPI — the goal is cheaper clicks and more bookings, and the score improves as a side effect of fixing the components. Optimizing "for QS" directly leads to strange decisions, like pausing profitable keywords because their grade offends you.
Don't mass-pause everything Below average. A Below-average keyword that books surgeries is doing its job at a bad price; the move is to fix its ad group and landing page, not delete the revenue.
Don't panic at the dashes. Low-volume keywords in a local account often never accumulate enough data to grade. Silence isn't failure.
Where this leaves you
Three columns, five minutes, and you'll know something most practice owners never learn: exactly where Google thinks your account is weak, component by component — which is also a map of what it's overcharging you for. Structure problems show up in the first two columns. Website problems show up in the third. And the fix for each one is documented, buildable, and shows up on your invoice as clicks that cost less.
If you'd rather have the reading done for you, get a free audit — the three columns above are among the first things I pull, and I'll tell you which component is costing you, what it would take to fix, and what your clicks should cost once it's fixed.
