Quick definition
Click-through rate (CTR) is the percentage of people who clicked your link after seeing it: clicks ÷ impressions × 100. It measures action, not applause.
Metrics
Part of the SocialKit social media glossary — browse every term.
CTR is clicks divided by impressions, expressed as a percentage. It applies anywhere a link can live: link posts, ads, the link in your bio, Story link stickers, and buttons on a business profile. Where engagement metrics measure how people reacted inside the feed, CTR measures the moment that matters commercially — someone choosing to leave the platform and visit your site.
Likes happen in the feed; revenue happens off it, and CTR is the bridge between the two. Timing and context shape click intent — someone skimming during a commute behaves differently from someone browsing on a couch in the evening. Placement matters too: many marketers observe that posts with outbound links often earn less reach than native content (platforms don’t publish those rules), which is why tactics like putting the link in the first comment or routing clicks through a link-in-bio page are so common.
A product announcement earns 20,000 impressions and 240 link clicks — a CTR of 1.2%. You rewrite the call-to-action from “link in bio” to “see the full pricing breakdown — link below,” republish to a comparable audience, and get 360 clicks on similar impressions: 1.8%. A 50% improvement in clicks from one sentence, measurable only because you were tracking CTR.
Ad platforms report CTR natively. For organic posts, add UTM parameters to your links so web analytics can attribute the traffic, or use a link shortener with click counts. To improve it: one clear call-to-action per post, a specific promise about what is behind the link, and the link placed where the platform actually makes it clickable.
