Click-Through Rate (CTR)
Also known as: CTR, click rate
Definition
Click-through rate (CTR) is the percentage of people who saw a link and clicked it — calculated as clicks divided by impressions, multiplied by 100.
CTR measures how compelling a link is once it is shown. It is the primary efficiency metric for paid ads, email subject lines, search results, and social posts with link stickers or bio links. A high CTR means the headline, image, and offer are doing their job; a low CTR means the audience is seeing the link but not finding it worth clicking.
CTR varies enormously by channel. Google Search ads average 6-8% CTR, Meta feed ads sit around 1-2%, Instagram Story link stickers convert at 3-5%, and email subject lines that work usually drive 2-5% click rates. Anything dramatically below the channel benchmark is usually a creative problem (weak headline, poor image, mismatched audience), not a delivery problem.
For social media, CTR matters most on Stories, ads, and email-to-social campaigns. On feed posts, link clicks are typically a secondary metric — saves, shares, and comments do more for ongoing reach. The exception is bio-link clicks, which are the closest organic-social equivalent of a paid CTR and are worth tracking weekly.

Frequently asked questions
What is a good CTR on social media?
Benchmarks vary by placement: 1-2% for Meta feed ads, 3-5% for Instagram Story link stickers, 0.5-1.5% for LinkedIn ads. Beat your channel's median and you are doing well.
What is the difference between CTR and conversion rate?
CTR measures how many people clicked the link. Conversion rate measures how many of those clickers completed the desired action (purchase, signup, download). High CTR with low conversion usually means the landing page does not match the ad promise.
How do I improve a low CTR?
Test headlines first (single biggest lever), then images, then audience targeting, then offer. Most CTR problems are a creative-message mismatch, not a delivery problem.
