What Is the Google Ads Quality Score and How Can It Be Improved?

Google Ads Quality Score is a critical metric that influences both the visibility and cost of your ads. Assigned on a scale from 1 to 10, it measures how relevant and useful your ads are to users, based on the keywords you’re targeting. A higher Quality Score means Google considers your ad highly relevant, which can lead to lower costs per click and better ad placements.

The Quality Score is calculated using three core components:

1. Expected click-through rate (CTR) – how likely someone is to click your ad

2. Ad relevance – how closely your ad matches the user’s search intent

3. Landing page experience – how useful and relevant your landing page is to visitors

A low score suggests that one or more of these elements need improvement. By focusing on these areas, businesses can boost their Google Ads Quality Score and maximise the return on their ad spend.

Why Google Ads Quality Score Matters

A higher Google Ads Quality Score can significantly reduce your campaign costs and improve performance. Google rewards advertisers who create relevant, user-friendly experiences by offering lower cost-per-click (CPC) rates and better ad placements. In competitive markets, this can mean the difference between consistent conversions and a wasted budget.

Improving your Quality Score doesn’t just impact one campaign — it improves your overall account performance. A consistently strong score across your campaigns tells Google that your ads are valuable and worth prioritising in auctions. This leads to higher impression share, better average positions, and ultimately, more leads or sales.

According to yellowHEAD’s comprehensive guide, businesses that consistently refine their ad copy, keyword targeting, and landing page quality see long-term improvements in their Quality Scores — and in their bottom line.

How to Improve Google Ads Quality Score

To increase your Google Ads Quality Score, start by aligning your ad copy with the specific keywords you’re targeting. Use keywords naturally in your headlines and descriptions, and make sure the message is directly relevant to what users are searching for.

Next, optimise your landing pages. Each landing page should load quickly, be mobile-friendly, and directly reflect the content of the ad. If someone clicks an ad for a product or service, the landing page must provide exactly that — no distractions or irrelevant content.

Monitoring your campaign metrics is also essential. Track CTR, bounce rate, and conversion rate to identify underperforming elements. Low CTRs, for instance, might indicate weak messaging or poor targeting. Test different ad variations regularly to find what resonates best with your audience.

Finally, make use of ad extensions like sitelinks and callouts. These not only increase the size of your ad but can also improve your CTR — a major component of Quality Score. Over time, even small improvements in these areas can lower your Google advertising fee and improve your overall ad performance.
