Click-through rate (CTR) measures how many people click on a link after seeing it.
It’s one of the simplest ways to tell whether your website listing, ad, or email is actually catching people’s attention.
How is CTR calculated?
CTR is expressed as a percentage. The formula is simple:
(Number of clicks ÷ Number of impressions) × 100 = CTR
An impression is counted every time your link is shown to someone. So if 1,000 people see your link in Google’s search results and 40 of them click on it, your CTR is 4%.
Where is CTR used?
You’ll come across CTR in a few different places:
Search engine results (SEO) — the percentage of people who click your page after seeing it listed on Google or Bing.
Paid ads (PPC) — how often people click your advert after it’s been displayed to them.
Email marketing — how many recipients click a link within an email you’ve sent.
In each case, CTR tells you the same thing: out of everyone who saw your link, how many were interested enough to act on it?
What is a good CTR?
It depends on the context. For organic search results, a CTR of 2–5% is fairly typical — though the top result on Google often sees much higher. For paid ads, average CTRs tend to sit around 1–3%, varying by industry.
The most useful benchmark, though, is your own. Rather than chasing a fixed number, track your CTR over time and focus on improving it steadily.
Why does CTR matter?
A strong CTR means your title, description, or ad copy is doing its job — it’s convincing people to want to find out more. A low CTR is a signal that something might need attention, whether that’s your headline, your meta description, or whether you’re reaching the right audience at all.
For SEO specifically, CTR also sends a signal to search engines. If lots of people are clicking your result, Google takes that as a sign your page is relevant and useful — which can help your rankings over time.

How do I improve my CTR?
A few straightforward things can make a real difference:
✓ Write clear, specific page titles that tell people exactly what they’ll find
✓ Make your meta descriptions compelling — treat them like a short pitch for your page
✓ Use natural language that matches the way your audience actually searches
✓ Test and refine — small tweaks to wording can produce noticeable improvements
CTR is about making a good first impression. Before anyone visits your website, they see your listing — and that listing needs to give them a reason to click.
CTR gets people to your site. Then what?
Once a visitor lands on your page, a different metric takes over: conversion rate. That’s the measure of how many visitors actually do what you’re hoping they’ll do, whether that’s making a purchase, filling in a form, or getting in touch. For more, check out: What is Conversion Rate?
