Google Ads Quality Score: How to Optimise for Better Ad Performance

Optimising your Quality Score in Google Ads is one of the most effective ways to improve ad performance while reducing costs. Quality Score is a diagnostic metric that reflects the relevance and effectiveness of your ads, keywords, and landing pages. It’s scored from 1 to 10 and directly influences your Ad Rank and cost per click (CPC).

A high Google Ads Quality Score signals to Google that your ads provide a good user experience, which often results in better ad placements at a lower cost. On the other hand, a low score can lead to higher CPCs and limited visibility, even if you’re bidding aggressively.

Focusing on the key components of Quality Score — ad relevance, expected click-through rate (CTR), and landing page experience — is essential for creating successful campaigns.

Why Google Ads Quality Score Matters

Google Ads Quality Score plays a crucial role in how your ads compete in Google’s auction system. It affects your Ad Rank, which determines both your ad position and the amount you pay per click.

By improving Quality Score, you can:

• Achieve higher ad placements without increasing your bids

• Lower your average CPC

• Boost your overall return on investment (ROI)

• Improve the effectiveness of your entire account

According to yellowHEAD’s guide to Quality Score optimisation, even incremental improvements in ad copy, keyword relevance, and landing page design can significantly impact performance.

How to Optimise Google Ads Quality Score

Improving Google Ads Quality Score starts with focusing on three key areas:

1. Ad Relevance
   Ensure your ad copy closely matches the user’s search intent. Use targeted keywords in both the headlines and descriptions to signal to Google — and the user — that your ad is relevant.

2. Expected Click-Through Rate (CTR)
   Write compelling, action-oriented ad copy that encourages clicks. Strong CTAs such as “Get a Quote”, “Buy Now”, or “Start Free Trial” can improve CTR over time.

3. Landing Page Experience
   Your landing page should be highly relevant to the ad and keyword, load quickly, and provide a seamless user experience. Make sure it’s mobile-friendly and free from distractions.

Additional best practices include:

• Using tightly themed ad groups to keep ads and keywords aligned

• Adding negative keywords to filter out irrelevant traffic

• Testing multiple ad variations to identify what performs best

• Using ad extensions to increase engagement and provide more value to users

Over time, these strategies will not only improve your Quality Score but also reduce your Google advertising cost by increasing efficiency and ad relevance.
