Click-Through Rate (CTR)

Click-through rate is the percentage of people who click on an ad or link after seeing it, calculated by dividing clicks by impressions. A higher CTR generally signals that your ad copy and targeting resonate with your audience. CTR is a key quality signal used by platforms like Google Ads to determine ad rank and cost efficiency. Why it matters: CTR is one of the strongest indicators of ad relevance, and Google uses expected CTR as a core component of Quality Score. Improving CTR can lower your cost per click and improve your ad position without increasing bids, creating a compounding efficiency gain over time. The average CTR for Google Search ads across all industries is roughly 3 to 6 percent, while Display Network ads average well under 1 percent. A CTR significantly below your industry benchmark suggests that your ad copy, keyword targeting, or audience selection needs refinement. To improve CTR, marketers should test compelling headlines, include strong calls to action, use ad extensions to occupy more screen real estate, and ensure tight alignment between keywords and ad copy. Monitoring CTR at the keyword level, rather than just the campaign level, reveals which specific terms drive engagement and which waste impressions.
