What Is CTR? Click-Through Rate Explained (Formula + How to Read It)
CTR (click-through rate) is clicks divided by impressions, as a percentage. It's the clearest signal of how compelling your ad is. Here's the formula, what's a good CTR, and the traps to avoid.
CTR (click-through rate) is the percentage of people who clicked your ad after seeing it: clicks ÷ impressions × 100. It's the single clearest signal of whether your creative and message are compelling enough to earn attention.
The CTR formula
CTR = (Clicks ÷ Impressions) × 100
Example: 1,500 clicks from 100,000 impressions is a CTR of 1.5%. On most platforms you'll watch the link CTR (clicks to your site) rather than all clicks, which include likes and expands.
What CTR tells you
- A healthy CTR means the hook and offer resonate with the audience.
- A falling CTR over days is usually the first sign of ad fatigue.
- High CTR but low conversions points to a mismatch between ad and landing page.
- Very high CTR with poor results can signal clickbait or the wrong audience.
What is a good CTR?
Benchmarks differ by platform, placement and industry, so compare against your own baseline rather than a borrowed number. The trend matters more than the absolute: a CTR that's drifting down on a previously strong ad is a clearer signal than any benchmark.

Frequently asked questions
- What is a good CTR for ads?
- It depends on the platform, placement and industry, so the most useful benchmark is your own history. Watch the trend: a declining CTR on a previously strong ad signals fatigue, regardless of the absolute number.
- Does a high CTR always mean a good ad?
- No. A high CTR with weak conversions can mean clickbait, a wrong audience, or a landing page that doesn't match the ad. Read CTR alongside conversion rate and CPA.
- How is CTR related to CPC?
- They're linked through CPM: a higher CTR generally lowers your CPC because you earn more clicks from the same impressions. Improving CTR is one of the most reliable ways to bring CPC down.
