Click-Through Rate (CTR)
Also known as: Click-Through Rate
CTR (Click-Through Rate) is the percentage of people who click a link, ad, or search result after seeing it — clicks divided by impressions.
CTR tells you how appealing your message is to the people who see it. It applies everywhere an impression is counted — paid ads, Google search listings, email links and social posts.
In paid search, CTR feeds directly into your Quality Score, which brings down your cost per click — so a higher CTR makes your ads more effective and cheaper at the same time. In organic search, CTR is a signal that your title and description are doing their job.
But a high CTR alone is not automatically good — clicks that don't convert only cost you money. Always read CTR together with conversion rate, so you know you are attracting the right clicks, not just more clicks.
Formula
CTR = (Clicks ÷ Impressions) × 100
Example
An ad shown 10,000 times that receives 250 clicks has a CTR of (250 ÷ 10,000) × 100 = 2.5%.
