What Is the Google Ads Quality Score and How Does It Affect Ad Costs?

The Google Ads Quality Score is a metric that evaluates the relevance and quality of your keywords, ads, and landing pages. It plays a crucial role in determining how much you pay per click and where your ads appear in search results.

This score, ranked from 1 to 10, directly affects your ad’s performance in Google’s auction system. A higher score indicates that your ad experience is closely aligned with what users are searching for, which can lead to a lower cost per click (CPC) and better ad positioning.

If your ads have a low Quality Score, Google sees them as less relevant — meaning you’ll need to bid more to compete. Improving your score can reduce your Google advertising cost while increasing your visibility.

Why Is Quality Score Important in Google Ads?

Google Ads Quality Score affects three key areas: CPC, ad rank, and eligibility. With a higher score, your ads can achieve better positions even with a lower bid. This gives businesses a competitive edge and helps maximise return on ad spend.

Google considers several factors when assigning a Quality Score:

• Expected click-through rate (CTR)

• Ad relevance to the keyword

• Landing page experience

According to Digilari’s guide to Quality Score, improving Quality Score requires regular optimisation of your ad copy, keyword targeting, and landing page content. The goal is to ensure users find your ad useful and relevant to their search intent.

How Quality Score Impacts Cost and Performance

The Quality Score doesn’t just influence your CPC — it also impacts how often your ad is shown. Google’s algorithm rewards relevant ads with higher visibility and lower costs, making it a vital metric for any advertiser.

Let’s say two advertisers are bidding on the same keyword. If one has a higher Quality Score, they’ll likely pay less per click and appear above the competitor in search results. This makes Quality Score one of the most cost-effective levers in your Google Ads strategy.

If you’re focused on lowering your Google advertising fee while improving ROI, prioritising Quality Score is one of the most effective tactics available.
