Click-Through Rate (CTR)
Click-through rate (CTR) is the percentage of people who click on a link, ad, or search result after seeing it. CTR stands for click-through rate. It measures how effectively a headline, ad creative, or search snippet captures attention and drives the next click. Marketers use CTR to evaluate ads, emails, organic search results, and any other content that competes for attention.
The CTR Formula
CTR is calculated by dividing clicks by impressions and multiplying by 100:
CTR = (Clicks / Impressions) × 100
An ad that receives 250 clicks on 10,000 impressions has a CTR of 2.5%. A search result that gets 80 clicks on 4,000 impressions has a CTR of 2%.
The formula stays the same across channels, but the inputs change:
- Paid ads: clicks on the ad divided by ad impressions
- Organic search: clicks on the result divided by search impressions
- Email: link clicks divided by emails delivered
- Social posts: link clicks divided by post impressions
- Display banners: clicks on the banner divided by served impressions
In email marketing, CTR (clicks divided by delivered) is different from click-to-open rate or CTOR (clicks divided by opens). CTOR isolates content performance from subject line performance. Both are useful; they answer different questions.
What Is a Good CTR?
A good CTR depends on the channel, the audience intent, and the position in the funnel. Search ads outperform display ads because the user has already signaled intent by typing a query. Compare CTR against the channel benchmark, not against a universal number.
| Channel | Average CTR | Source |
|---|---|---|
| Google Search Ads | 6.11% | WordStream benchmarks |
| Google Display Network | 0.46% | WordStream benchmarks |
| Facebook Ads | 0.90% | WordStream benchmarks |
| LinkedIn Sponsored Content | 0.44% to 0.65% | LinkedIn benchmarks |
| Organic search position 1 | 27.6% | Backlinko 2023 (4M results study) |
| Email marketing (all industries) | 2.13% | Mailchimp benchmarks |
Organic CTR drops sharply by position. According to the Backlinko 2023 study of 4 million Google search results, position 1 averages 27.6%, position 2 drops to 15.8%, and position 10 sits at 2.4%. Moving from position 3 to position 1 typically more than doubles organic clicks at the same impression volume.

Types of CTR
Organic CTR: Clicks on a search result divided by search impressions. Found in Google Search Console under the Performance report. Useful for testing title tags and meta descriptions.
Paid Ad CTR: Clicks on an ad divided by ad impressions. Reported in Google Ads, Meta Ads Manager, and LinkedIn Campaign Manager. A core input for Google’s Quality Score, which directly affects cost per click and ad rank.
Email CTR: Link clicks divided by emails delivered. Tracked in Mailchimp, Klaviyo, HubSpot, and most email service providers.
Social Post CTR: Link clicks divided by total impressions on a post. Lower than search CTR because social audiences are not actively searching for the offer.
Display CTR: Clicks on a banner ad divided by impressions. Typically the lowest CTR of any paid format because of banner blindness and broad targeting.
Common CTR Mistakes
Comparing CTR across channels with different intent. A 6% search ad CTR is average; a 6% display ad CTR is exceptional. Channel context matters more than the raw number.
Optimizing for CTR alone. A clickbait headline can lift CTR while tanking conversion rate. Always pair CTR with downstream metrics like conversion rate and cost per acquisition.
Treating CTR as a Google ranking factor. Google’s John Mueller has stated multiple times that CTR is too noisy and easy to manipulate to be used in core search rankings. Higher CTR reflects relevance; it does not cause higher rankings.
Ignoring position when reading organic CTR. A drop in CTR is often a drop in position, not a worse snippet. Check average position before rewriting titles.
Confusing email CTR with click-to-open rate. CTR uses delivered emails; CTOR uses opened emails. Mixing the two produces incorrect comparisons across campaigns and tools.
Frequently Asked Questions
What does CTR stand for?
CTR stands for click-through rate. It is the percentage of viewers who click on a link, ad, or search result out of the total who saw it. The metric appears in Google Ads, Meta Ads Manager, Google Search Console, and most email marketing platforms.
How do you calculate CTR?
CTR = (Clicks / Impressions) × 100. An ad that received 250 clicks on 10,000 impressions has a CTR of 2.5%. Most reporting platforms calculate CTR automatically. The manual formula is useful for spot checks or when reconciling data from two different sources.
What is a good CTR rate?
A good CTR depends on the channel. Google Search ads average around 6.11% across industries (WordStream). Google Display ads average 0.46%. Facebook Ads average 0.90%. Organic position 1 averages 27.6% according to Backlinko’s 2023 study of 4 million search results. Compare to your channel benchmark, not to a universal number.
Is CTR a Google ranking factor?
Google does not use CTR as a direct ranking signal. Google’s John Mueller has stated that CTR data is too noisy and prone to manipulation to be used in core ranking. A high CTR signals relevance to user intent, which Google rewards through other signals; the CTR itself does not push the page up.
What is the difference between CTR and conversion rate?
CTR measures how many people clicked after seeing something. Conversion rate measures how many people completed a desired action after clicking. A landing page can have high CTR and low conversion rate (the headline works, the page does not), or low CTR and high conversion rate (few people click, but those who do convert at a high rate).
