What Is Quality Score in Google Ads?

Understand Quality Score in Google Ads

Use the diagnostic to improve the customer journey

Quality Score in Google Ads is a diagnostic for Search keywords, shown on a scale from 1 to 10. It reflects expected click-through rate, ad relevance and landing page experience relative to other advertisers. The displayed score is not a direct auction input, and a high score does not prove that a campaign is profitable.

Use it to identify areas worth investigating. The business result still depends on the searches reached, the offer and what happens after the click.

Our Google Ads management reviews connect diagnostic evidence with relevant enquiries and sales. If you are new to paid search, start with our beginner’s guide to Google Ads.

What Quality Score can tell you

Quality Score compares aspects of the advertising experience for eligible Search keywords. It can highlight where the advert or destination may be weaker than the comparison group.

It does not tell you whether an enquiry was suitable, whether a customer bought or whether the job was profitable. A useful diagnostic and a useful commercial outcome are different kinds of evidence.

Google’s Quality Score guidance describes it as a diagnostic rather than a performance target. Avoid presenting an average score across the account as a substitute for business results.

The three components

Expected click-through rate

This estimates the likelihood that the advert will be clicked when shown. It is different from simply reading the actual click-through rate in your campaign report.

A compelling message should help the right customer recognise the offer. Attracting curiosity clicks from people who do not want your service is not a useful objective, even if those clicks make a report look busy.

Ad relevance

This considers how closely the advert matches the intent behind the search. Check whether the message answers the need represented by the keyword theme.

For example, an advert about emergency repairs should make that service clear. A broad message about everything the company does may leave the searcher uncertain whether the immediate need can be met.

Landing page experience

This considers how useful and relevant the destination is after the click. The page should explain the offer, help people navigate and make the next step clear.

A service page needs more than repeated keywords. Explain what is available, who it suits and how to enquire. Check the mobile experience and whether forms and telephone links work.

How to find the score

In the Search keyword view, use the columns control to add Quality Score and its component assessments. Google also provides historical diagnostic columns where available.

Review the components alongside the keyword and its destination. A below-average assessment can identify an investigation; it does not tell you exactly which sentence or page element caused it.

If a score is unavailable, do not assume it means the keyword has failed. Google may not have enough qualifying search data to display a score. Assess relevance and outcomes using the other evidence available.

Quality Score and Ad Rank

The displayed 1–10 score is not the same as Ad Rank. Google assesses quality in the context of individual auctions, alongside bids and other factors that affect eligibility and placement.

Google’s ad quality explanation describes how the underlying experience can influence showing, position and cost. That does not make the visible diagnostic a price formula.

It would be misleading to claim that moving from 6/10 to 8/10 automatically cuts click costs by a fixed percentage. Improvements can matter, but the auction and market continue to vary.

A practical landing page example

Imagine an advert for bespoke conservatories that sends visitors to a general home improvement homepage. The service may be available, but visitors have to find it among unrelated products.

A dedicated page could explain the conservatory range, coverage, quotation process and enquiry options. That is an illustrative improvement to the customer journey, rather than a claim about a particular client result.

Check whether suitable enquiries improve after the change. Record other changes made during the same period so the result is interpreted fairly. The page can become more helpful even if the diagnostic does not immediately move.

A verified observation with clear limits

For an anonymous commercial flooring contractor in Essex, we reviewed search terms and added appropriate negative keywords following discussion with the client. We subsequently observed stronger click-through rates and Quality Scores alongside more forms and high-intent calls.

That observation did not isolate one change in a controlled test. It therefore does not prove that negatives directly raise Quality Score or that an improved score caused the additional enquiries.

The practical lesson is to connect a diagnostic with search relevance and customer feedback. Report what happened while remaining clear about what the evidence cannot establish.

Improve the experience in a useful order

Start with a specific concern, such as a relevant service keyword sending visitors to a general page. Check the matching, advert promise and destination before deciding what to alter.

If the advert is unclear, test a more accurate message. If the destination is unhelpful, improve the service explanation and enquiry route. Keep the changes purposeful instead of rewriting the account solely to obtain a higher displayed score.

Measure customer outcomes after the change. A clearer page can also qualify visitors, reducing unsuitable enquiries while helping appropriate customers decide. Raw conversion volume may not capture that improvement.

Keep commercial performance in view

A high score can coexist with poor lead quality or unprofitable work. Equally, a campaign does not need a perfect score on every keyword to contribute valuable customers.

Review advertising cost per enquiry, the proportion of suitable leads and the work won, where that information is available. Our UK Google Ads cost guide explains why affordability depends on the business.

Quality Score should help you choose an investigation. It should not become a reason to ignore a broken form, weak offer or unsuitable search theme.
