Quality Score is a 1-to-10 rating Google Ads assigns to every keyword in your account, built from three inputs: expected click-through rate, ad relevance, and landing page experience.

It is Google’s shorthand for how well your ad, and the page behind it, matches what someone actually typed into the search bar. That’s the whole concept. The confusion starts later.

Here’s the part most explainers skip: Google’s own documentation states that Quality Score itself is not an input in the ad auction. It’s a diagnostic tool, not a bidding lever.

That one sentence has started more r/PPC threads than almost anything else in Google Ads, and it’s also why so many accounts spend hours chasing a number that was never built to be chased directly.

This guide covers both halves: what the score actually measures, what counts as good, and what changes when you improve it (and what doesn’t).

Quality Score Measures Three Things, Not One

Every keyword with enough search volume to be evaluated gets a score from 1 to 10, visible at the keyword level inside your account.

Google builds that number from three separate checks, and reports each one back individually as Below average, Average, or Above average, the exact wording you’ll see in your own dashboard once you know where to look.

Expected click-through rate

This is a prediction, not a measurement of your actual results. Google estimates how likely someone is to click your ad for that keyword and match type, compared with other ads that have shown in a similar position for similar searches.

A brand-new keyword with no history often starts at Average by default, simply because Google has nothing to compare yet.

Worth calling out: “Below average” does not mean your real click-through rate is bad.

Practitioners on r/PPC have flagged keywords marked Below average with actual CTRs above 20%, because the label reflects a relative prediction against a shifting pool of competitors, not your dashboard’s own CTR column. Read the two side by side before assuming something is broken.

Ad relevance

This one is closer to a straight text match: how closely your headlines and description connect to the intent behind the keyword.

An ad group built around five loosely related keywords will almost always score worse here than one built around a single, specific intent, because Google is checking whether the ad you wrote actually answers the search someone typed, not whether it’s clever copywriting.

One search intent per ad group is still the single highest-leverage structural fix here.

Landing page experience

Relevance, clarity, and how easy the page is to act on, benchmarked against other advertisers bidding on similar keywords, not against an absolute checklist.

This is the component that generates the most frustration, because a landing page that converts well and loads fast can still land on Average.

That’s a comparison problem, not a bug: if your competitors’ pages have also gotten faster and more targeted, the bar moves with them.

Where to Actually Find Your Quality Score

It’s not on your account’s main dashboard. You have to add it as a column, and most accounts never do.

1. Open your account and go to Campaigns > Audiences, keywords and content > Search keywords.
2. Click the Columns icon (three stacked lines) above the keyword table.
3. Open the Quality Score section and add Quality Score plus the three status columns: Exp. CTR, Ad Relevance, and Landing page exp.
4. Apply, then sort the table by Quality Score to find your worst performers first.

New or low-volume keywords will show a dash instead of a number. Google needs a minimum amount of search activity before it reports a score at all; a dash isn’t a bad score, it’s no score yet.

Does a Higher Quality Score Actually Lower Your Cost Per Click?

The relationship most people were taught: Ad Rank equals Max CPC bid multiplied by Quality Score. It’s a useful mental model, and it’s also a simplification Google no longer uses literally.

The real Ad Rank calculation, per Google’s own documentation, weighs your bid, ad quality, Ad Rank thresholds, the competitiveness of the auction, the context of the search (device, location, time), and the expected impact of extensions and other ad formats.

Quality Score, the 1-to-10 number in your dashboard, isn’t on that list. Ad quality is.

The practical result lands the same either way: accounts with consistently strong expected CTR, ad relevance, and landing page signals do pay less for the same position, because those are the exact things the real-time ad quality assessment is scoring, every single auction.

The 1-to-10 number is just a delayed, rounded-off progress report on work you already did.

What a Good Quality Score Actually Looks Like

1 to 4 is genuinely poor and often comes with a visible warning: “Rarely shown (low Quality Score)” next to the keyword.

5 to 6 is average, functional but with obvious room to improve. 7 to 8 is good, and a realistic target for most keywords with a properly matched ad group and landing page.

9 to 10 is excellent and, on competitive, high-volume terms, genuinely rare; branded keywords for your own company name will often sit at 9 or 10 by default, simply because nothing matches search intent better than your own brand name pointing at your own website.

Google is explicit that the score measures “how well your ad quality compares to other advertisers,” which means good is relative to your specific auction, not a fixed bar.

A 6 in an intensely competitive industry, like insurance or legal services, can represent more real optimization work than an 8 in a niche with three total advertisers.

Is Google’s Quality Score Actually Broken?

A widely discussed r/PPC thread asked exactly this, and the frustration was specific: keywords marked “Rarely shown (low Quality Score)” despite being obviously relevant to the business.

Expected CTR marked Below average on core terms converting at real click-through rates north of 20%, and landing page scores that didn’t move even after genuine, tested improvements.

One of the most upvoted replies in that thread quoted Google’s own support documentation back at the original poster:

“Quality Score is not an input in the ad auction. It’s a diagnostic tool to identify how ads that show for certain keywords affect the user experience.”

Both things are true at once, and that’s the actual resolution, not a dodge.

The reported score is exactly what Google says it is: a diagnostic, recalculated periodically, not consulted live at auction time.

But the three things behind it, expected CTR, relevance, landing page quality, are absolutely part of the real-time ad quality assessment that does run every auction. What’s likely driving the “this makes no sense” feeling isn’t a broken metric.

It’s a moving comparison group: more advertisers entering an auction, broad match pulling in a wider spread of search terms per keyword, and Performance Max blending signals across campaigns all change who you’re being measured against.

That changes your relative score even when your own ad and page haven’t changed at all.

That’s not a broken scorecard. That’s a scorecard graded on a curve that keeps adding students.

Your move: stop reporting Quality Score to stakeholders as a KPI. Use it exactly the way Google says to, as a first-pass diagnostic to find your worst-performing 10% of keywords, then judge everything else, and everything you report upward, by cost per conversion and conversion rate.

How to Improve a Low Quality Score

None of this requires guessing. Work the three components in this order, because each one unblocks the next.

1. Split ad groups by search intent, not by product category. A single ad group covering five loosely related keywords cannot write one relevant headline for all five. Smaller, tighter groups fix ad relevance faster than any copy edit.
2. Rewrite headline one to mirror the keyword’s actual language. Not a synonym, not a rephrase, the words someone actually typed.
3. Add negative keywords weekly, not quarterly. Every irrelevant search term that triggers your ad drags down expected CTR for the whole keyword.
4. Fix landing page load speed before anything else on the page. Run it through PageSpeed Insights and compare mobile and desktop separately; mobile is usually where the real problem hides.
5. Match the landing page headline to the ad’s specific promise. If the ad says “same-day quotes,” the page someone lands on should say it too, above the fold, not three scrolls down.

A Quality Score of 10 that never converts is not a win. A Quality Score of 5 that fills the pipeline is.

When to Stop Chasing the Number

Quality Score earns its keep as an early-warning system: it flags the keywords worth a second look before you’ve spent enough to notice in your conversion data. Past that point, it should step aside.

Cost per conversion, conversion rate, and actual return on ad spend are the numbers that pay your bills; Quality Score is not one of them, and Google has said as much directly.

If your account is large enough that watching the Quality Score column has become its own part-time job, that’s usually a sign the account needs a second set of eyes more than it needs another optimization script.

Deciding what to test, what to cut, and what to leave alone is a fair amount of what our paid search and PPC management work actually looks like day to day.

The score was only ever a proxy for one thing: whether a stranger who searched for something specific found what they were looking for when they clicked. Get that right, consistently, and the number takes care of itself.

Quick Answers to Common Quality Score Questions

Is Quality Score a ranking factor in the Google Ads auction?

Not directly. Google states plainly that Quality Score itself is not an input in the ad auction, it’s a diagnostic tool.

The three things it measures do feed the real-time ad quality assessment that affects Ad Rank, but that’s a separate, live calculation from the 1-to-10 number in your dashboard.

Does pausing and reactivating a keyword reset its Quality Score?

No. Quality Score is tied to the keyword’s accumulated performance history, not its current status.

Pausing doesn’t erase that history, and reactivating it picks up close to where the score left off, though a long enough pause can leave it stale until fresh data comes in.

How often does Quality Score update?

It’s recalculated regularly based on recent performance, not in real time during each auction. Expect the number to shift gradually as click and conversion data accumulates, rather than jumping the moment you make a single change.

Is a 10/10 Quality Score worth chasing for its own sake?

No. A perfect score with no conversions is a worse outcome than a 6 that fills your pipeline. Treat the score as a diagnostic for finding weak keywords, not a target metric in its own right.

Does keyword match type affect Quality Score?

Indirectly. Broader match types can pull a single keyword into a wider range of search terms, which changes the pool of data feeding its expected CTR and relevance signals.

That can make scores look noisier even when nothing about your ad or landing page has changed.
