What is Quality Score?

Quality Score is Google Ads' 1 to 10 rating of how relevant your ads, keywords and landing pages are compared with other advertisers on the same keyword.

Many advertisers believe the biggest budget always wins on Google. It does not. Google wants searchers to see useful ads, so it rewards relevance. Quality Score is the number that shows how relevant Google thinks your ads are.

Quality Score is a rating from 1 to 10, given to keywords in your Google Ads account. It compares your ad experience with other advertisers who showed ads for the same keyword in the recent past.

The three parts

Expected click-through rate: how likely people are to click your ad when it shows for that keyword.
Ad relevance: how closely your ad matches the intent behind the search.
Landing page experience: how useful, relevant and easy to use your page is once people arrive.

Each part is marked "Above average", "Average" or "Below average". This tells you exactly where to work. Google shows a score only when a keyword has enough data, so new or very low-volume keywords may not show one at all.

What Quality Score is, and what it is not

This point is often misunderstood. Quality Score is a diagnostic tool. Google does not plug this 1 to 10 number directly into the auction. Instead, the auction uses real-time quality signals that measure similar things. A low-quality ad can end up paying more for a position, or not showing at all, even with a high bid.

In simple words, Quality Score is like a report card, not the exam itself. Improve what it measures and your auction results usually improve too, often with a lower cost per click.

An example

Imagine a physiotherapy clinic in Chennai bidding on "knee pain physiotherapy". Its ad says "Expert Physio Care" and sends people to the homepage, which talks about every service. The Quality Score sits at 4, with landing page experience below average.

The clinic writes a new ad, "Knee Pain Physiotherapy in Chennai, Book Today", and builds a dedicated landing page about knee treatment with timings, location and a call button. Now the ad and page match the search, so the rating has a good chance of climbing over the following weeks. The clinic may also see more calls, because people land on exactly what they searched for.

How to improve it

When my team at Thetechhacker audits a Google Ads account, low Quality Scores usually point to a handful of fixable issues:

Ad groups with too many unrelated keywords
Ad copy that does not mention the searched phrase or need
Slow or confusing landing pages, especially on mobile
Generic pages that do not answer the specific query

Page speed and clarity matter here just as they do for SEO, which is why a free SEO and AI audit report of your landing pages can be a useful first check.

Simple takeaway

Quality Score is Google's way of saying "show people what they asked for". Do not chase the number for its own sake. Make your ads and pages genuinely relevant, and the score, along with your costs, tends to follow.
