Click-through rate
see-tee-AR
The percentage of people who click your ad or link after seeing it. Clicks divided by impressions. Measures how compelling your message is.
CTR is the percentage of impressions that result in a click. If your ad was shown 10,000 times and 150 people clicked, your CTR is 1.5%.
CTR measures one thing: is this content compelling enough to click? A high CTR means your headline, image, and copy resonate with the audience. A low CTR means the audience saw your ad and kept scrolling.
Benchmarks vary wildly by channel. Google search ads: 3-5% CTR is good. LinkedIn ads: 0.5-1.0% is typical. Display ads: 0.1-0.3% is normal. Email: 2-5% is healthy. Compare your CTR to channel benchmarks, not across channels. A 0.5% CTR on display ads is fine. A 0.5% CTR on Google search ads means your ad copy needs work.
Examples
A Google Ads campaign with strong CTR.
Ad headline: 'Deploy to Production in 90 Seconds.' Impressions: 25,000. Clicks: 1,250. CTR: 5.0%. The headline matches the searcher's intent perfectly. They want faster deployments and the ad promises exactly that.
A/B testing improves CTR.
Headline A: 'Modern Deployment Platform' (CTR: 0.8%). Headline B: 'Eliminate Failed Deployments' (CTR: 2.1%). Headline B addresses a specific pain point. CTR increases 2.6x from one word change.
High CTR does not always mean success.
An ad promises a 'Free Deployment Toolkit.' CTR is 4.2%. But 90% of clicks bounce from the landing page because the 'toolkit' requires a sales conversation to access. High CTR, terrible conversion. The ad over-promised.

Frequently asked questions
What is a good CTR?
It depends on the channel. Google search ads: 3-5%. LinkedIn sponsored content: 0.5-1.0%. Display/banner ads: 0.1-0.3%. Email campaigns: 2-5%. Organic search: varies by position (position 1 gets 30%+ CTR). Always compare to channel-specific benchmarks.
How do you improve CTR?
Write specific, benefit-focused headlines. Address the audience's pain point directly. Use numbers and data when possible. Test multiple versions (A/B testing). Make sure your targeting reaches the right audience because the best ad copy will fail if shown to the wrong people.
