Google Ads Quality Score: What It Really Measures and How to Raise It

What Google Ads Quality Score actually is

Google describes Quality Score as a diagnostic tool meant to give you a sense of how well your ad quality compares to other advertisers. It is scored 1 to 10, it lives at the keyword level, and it is reported for Search campaigns.

The three components

Four details most advertisers miss

• It compares you to competitors. The evaluation is based on other advertisers whose ads showed for the exact same search over the last 90 days.
• It uses exact searches of your keyword. Changing a keyword's match type doesn't change its Quality Score.
• A dash means not enough data. If you see "—" there aren't enough exact searches yet to score it.
• It isn't the auction. Google states plainly that Quality Score is not an input in the ad auction.

That last point surprises people, so it gets its own section.

Why Quality Score still matters if it isn't the auction

Quality Score matters because it reflects the same things the auction cares about. At auction time, Google calculates Ad Rank using your bid, the quality of your ads and landing page, Ad Rank thresholds, competition, the context of the search and the expected impact of your assets. Quality Score is a summary of how your ad quality has been judged lately.

The most important line on Google's Ad Rank help page is this: you can still win a higher position at a lower price by using highly relevant keywords and ads. In plain terms, better quality lets you pay less for the same spot, or get a better spot for the same money. That is why the three components are worth fixing.

Think of Quality Score as the dashboard light, not the engine. When it turns red, something under the hood needs work. Taping over the light fixes nothing.

Google's own optimization guidance says the same: treat it as a general indicator of which areas to focus on, rather than a score to be optimized. Advertisers who chase the number for its own sake tend to make bad trades, like pausing keywords that convert well just because they score a 4.

How to read your Google Ads Quality Score

Turn on the right columns, sort by spend, and read the three components for each keyword. The overall score tells you that something is wrong; the components tell you what.

Add the columns

1. In Google Ads, open Campaigns, then Keywords.
2. Select the columns icon and choose to modify columns for keywords.
3. Open the Quality Score section and add Quality Score, Exp. CTR, Ad Relevance and Landing Page Exp.
4. Add the historical versions too, such as Quality Score (hist.), to see how scores looked over the date range you are viewing.

Google documents the full list of Quality Score columns, including segmenting by day to watch daily changes.

Use an impression-weighted score for the account

A simple average misleads you. Fifty tiny keywords scoring 8 can hide the one big keyword at a 3 that takes half your budget. We use an impression-weighted average instead:

1. For each keyword, multiply its Quality Score by its impressions.
2. Add those products together.
3. Divide by the total impressions of all scored keywords.

Track that one number monthly for each campaign. If it climbs while cost per conversion falls, your fixes are working. If the number climbs but leads don't, you are polishing the wrong keywords.

The Quality Score triage table

Every below-average rating points to a different fix. Find the weakest component on your highest-spend keywords and work down this table.

Work on the keywords that carry the most spend first. Raising a keyword with 20 impressions a month from a 5 to a 7 changes nothing you will notice. Raising the keyword that drives most of your clicks changes your whole cost structure.

How to raise expected CTR

Expected CTR improves when your ad looks like the obvious answer to the search. That comes from specific, intent-matched copy, not from tricks.

• Echo the intent. Someone searching "emergency plumber" wants speed. Lead with it: "Plumber On the Way in 60 Minutes" only if that is true.
• Be specific. Numbers, service names, areas and hours beat adjectives. "Licensed, Insured, Serving Broward Since 2010" beats "Quality Service You Can Trust."
• Use assets. Sitelinks, callouts, call assets and structured snippets make the ad larger and more useful.
• Write a clear call to action that matches what happens on the page.
• Add negative keywords. Irrelevant searches that show your ad and get ignored drag your CTR history down.

Google adds one caution worth repeating: a more specific ad may get fewer clicks but more conversions. A slightly lower CTR from the right people is a good trade. Never write a clickbait headline just to move this component.

How to raise ad relevance

Ad relevance improves when each ad group has one clear theme and every ad in it speaks to that theme. Google's guidance is to group keywords into themes and split ad groups whose keywords one ad can't serve well.

The single-theme test

Read the keywords in an ad group out loud, then read the ad. If any keyword makes the ad sound wrong, it belongs in a different group. "Water heater repair" and "tankless water heater installation" are different jobs with different buyers. They need different ads and, usually, different pages.

Practical steps

1. Pull the search terms report for the last 90 days and group real searches by theme.
2. Build ad groups around those themes, with 5 to 20 closely related keywords each.
3. Write responsive search ads whose headlines use the theme's language naturally.
4. Pin sparingly. Pinning one headline that names the service is often enough.
5. Recheck ad relevance after two to four weeks of data.

You don't need a separate ad group for every keyword. That approach creates more management than value. Aim for groups tight enough that one landing page and one message fit all of them.

How to raise landing page experience

Landing page experience improves when the page delivers exactly what the ad promised, loads quickly and works well on a phone. Google's guidance is short: give people what they're looking for.

The landing page checklist

• Message match: the headline repeats the ad's offer in similar words.
• One page per offer: don't send emergency repair clicks to your homepage.
• Speed on mobile: test on a real phone over cellular, not office wifi. Our guide to Core Web Vitals covers what to measure.
• Clear next step: a tap-to-call button and a short form above the fold.
• Trust: real photos, licenses, reviews and a physical presence.
• Transparency: say who you are and how to reach you.

Two things Google says don't matter here, which clears up common myths. The exact search phrase doesn't need to appear word for word on the page. And conversion rate doesn't affect the landing page status, though Google suggests it as a useful proxy for whether the page is working.

This is where a website team and an ads team need to work as one. We build ad landing pages in house through our web design and website improvement teams. For more on turning those clicks into leads, read how to improve website conversion rate.

A worked Google Ads Quality Score example

This is an illustrative example with round numbers, not a client account. It shows how to prioritize when you have limited time.

The simple average is 5.25. The impression-weighted score is (8,000 × 4 + 3,000 × 6 + 1,000 × 8 + 200 × 3) ÷ 12,200, which is about 4.8. The low-volume keyword at a 3 looks alarming but barely moves the account.

The priority is clear: "emergency plumber" carries about two-thirds of impressions and its landing page is the weak spot. Build a dedicated emergency page with a fast-loading call button and a headline that matches the ad. Then split "water heater repair" into its own ad group with its own ad. Leave "sewer camera inspection" alone until the big two are fixed.

Google Ads Quality Score vs the metrics that pay the bills

Quality Score is a means, not the goal. Watch cost per conversion, conversion volume and lead quality alongside it. A keyword with a 5 that produces booked jobs at a good cost is worth more than a keyword with a 9 that produces nothing.

A weekly Quality Score routine

Quality Score rewards steady maintenance more than big overhauls. Here is the 30-minute weekly routine we follow on Search accounts.

1. Search terms: review new searches and add negatives for anything irrelevant.
2. Top spenders: check the components for your 10 highest-spend keywords. Note any that dropped.
3. Ads: pause clear losers and add one new headline or description test per main ad group.
4. Landing pages: spot check speed and forms on a phone. Broken forms kill both quality and leads.
5. Tracking: confirm calls and forms are recording. If conversions stop, every decision gets worse.
6. Monthly: recalculate impression-weighted Quality Score per campaign and compare with cost per conversion.

Tracking is the step that makes the rest pay. In UnifiedIQ, our platform, every call and form is traced to its source, so we can see which keywords produce real inquiries, not just clicks. That keeps Quality Score work focused on the keywords that matter.

Where Quality Score doesn't apply

Quality Score is a keyword-level metric for Search campaigns. You won't find it for Performance Max, which is built around goals and assets rather than keyword lists. If you run both, read our guide to Performance Max campaigns for how to judge that side.

Quality Score myths that waste budget

Most bad Quality Score advice comes from treating the number as a target. These are the myths we undo most often in accounts we take over.

If an agency or tool promises to raise your score fast with account restructures alone, ask which of the three components they will change and how. If the answer doesn't involve better ads or better landing pages, it won't last.

When to get help with your account

Get help when spend is meaningful, scores are stuck below average on your main keywords, and you don't have the time or access to fix landing pages. Most Quality Score problems we see are really website problems or structure problems that a settings change can't fix.

For Aces Airboat Tours, we built five Google Ads campaigns alongside a 334-page website, and the site recorded 369 booking-button clicks in its first two months. Ads and landing pages were planned together from day one, which is how it should work.
