What is Google Ads Quality Score and why is it important?

The short answer: Quality Score is Google Ads' 1 to 10 rating of how relevant your keyword, your ad and your landing page are to the people searching for that keyword. It matters because Google's auction does not just reward the highest bid. A well-matched ad with a Quality Score of 8 can sit above a competitor bidding twice as much and still pay less per click.

The three parts of Quality Score

Google rates each part as above average, average or below average. You can see all three by adding the Quality Score columns to your keywords view.

• Expected click-through rate: how likely people are to click your ad for this keyword, compared with other advertisers.
• Ad relevance: how closely the ad's message matches what the person searched.
• Landing page experience: whether the page delivers what the ad promised, and loads fast on a phone.

Why it matters for your budget

Quality Score itself is a summary. The live auction uses real-time versions of the same factors. But the direction is reliable: better relevance means cheaper clicks and better positions. In practice it shows up in cost per lead. One of our Adelaide specialist practices, Transform Orthodontic Care, ran at $2.90 a click and $22.03 per consultation conversion over four months of optimisation. That came from tight ad groups, specific ads and landing pages that matched the treatment searched.

How to lift a low score

1. Split broad ad groups. If one ad group holds 40 keywords about different services, no single ad can be relevant to all of them. Group keywords by intent.
2. Write ads that use the searcher's words. Put the main keyword theme in a headline, and make the offer specific.
3. Send each ad group to the most specific page. An ad for "invisalign cost" should land on a page about Invisalign pricing, not your homepage.
4. Fix the landing page: mobile speed, a clear headline that matches the ad, and an easy call or form.
5. Add negative keywords every week so the ad stops showing for searches it cannot satisfy, which drags down click-through rate.

Do not chase a 10 on every keyword. Some valuable keywords will always sit at 5 or 6, and that is fine if the cost per lead works. For Google Ad Grants accounts, though, keywords scoring 1 or 2 are not allowed at all.
