CTR (click-through rate) is the share of people who click after seeing your ad, link or email. The formula is CTR = clicks ÷ impressions × 100. If your ad is shown 10,000 times and gets 250 clicks, your CTR is 2.5%. The CTR calculator above works that out for you. It can also tell you how many clicks a target CTR would bring, or how many impressions you need to reach a number of clicks.
In short
- CTR = clicks ÷ impressions × 100.
- A higher CTR means more of the people who saw your ad found it worth clicking.
- There’s no universal “good” CTR. It depends on the channel, the industry and the ad.
- CTR tells you about attention, not sales. Always check conversion rate and cost per acquisition too.
- A CTR from a handful of impressions isn’t reliable. Wait for enough data.
What is CTR?
CTR stands for click-through rate. It answers a simple question: of everyone who saw this, how many clicked?
You’ll see it in lots of places. Ad platforms like Google Ads and Meta report it for every ad. Email tools show it for every campaign. Google Search Console shows it for every page that appears in search results. The idea is the same each time: clicks divided by the number of times something was shown.
A high CTR usually means your message matches what people want. A low one usually means the ad, the headline or the audience isn’t quite right.
How to calculate CTR?
Divide the number of clicks by the number of impressions, then multiply by 100 to turn it into a percentage.
| What you want | Formula |
|---|---|
| CTR | clicks ÷ impressions × 100 |
| Clicks | impressions × CTR ÷ 100 |
| Impressions needed | clicks ÷ (CTR ÷ 100) |
| Cost per click (CPC) | ad spend ÷ clicks |
| CPC from CPM and CTR | CPM ÷ (1,000 × CTR as a decimal) |
Here are the steps:
- Find the number of clicks for a set period.
- Find the number of impressions for the same period.
- Divide clicks by impressions.
- Multiply by 100.
In a spreadsheet, put clicks in A2 and impressions in B2, then type =A2/B2 and format the cell as a percentage.
Use the same dates for both numbers and the same kind of click. Some platforms report “link clicks” and “all clicks” separately, and mixing them gives a wrong CTR.
CTR examples
Example 1: Find the CTR
Your ad got 250 clicks from 10,000 impressions. CTR = 250 ÷ 10,000 × 100 = 2.5%. That’s about one click for every 40 impressions.
Example 2: Find the clicks
You expect 50,000 impressions and a CTR of 1.5%. Clicks = 50,000 × 1.5 ÷ 100 = 750.
Example 3: Find the impressions
You want 300 clicks, and your usual CTR is 2%. Impressions needed = 300 ÷ 0.02 = 15,000.
Example 4: add the cost
You spend $200 and get 250 clicks from 10,000 impressions.
- CTR = 250 ÷ 10,000 × 100 = 2.5%
- Cost per click = 200 ÷ 250 = $0.80
- CPM = 200 ÷ 10,000 × 1,000 = $20.00
Example 5: Why CTR changes your cost per click
Two ads both run at a $10 CPM. Ad A has a 1% CTR, so its cost per click is 10 ÷ (1,000 × 0.01) = $1.00. Ad B has a 2% CTR, so its cost per click is 10 ÷ (1,000 × 0.02) = $0.50. Same price for reach, half the cost per click. That’s why CTR matters.
Example 6: A CTR you can’t trust
An ad shown 20 times gets 1 click, a CTR of 5%. That looks great, but it’s one click. With so few impressions, the number can swing wildly. Wait for a few hundred or a few thousand impressions before you judge it.
What is a good CTR?
It depends on where the ad runs. These are typical figures from recent benchmark reports, and they don’t all agree, so treat them as a rough guide:
| Channel | Typical CTR |
|---|---|
| Google Search ads | about 3% to 6.6%, depending on the study |
| Google Display ads | about 0.5% |
| Meta (Facebook and Instagram) ads | about 2.4% median for ecommerce brands |
The Google Search figure varies a lot between studies. LocaliQ’s 2026 benchmark, covering more than 13,000 US campaigns, puts the average at 6.64%, while other roundups report about 3.17%. WebFX puts display near 0.46%, and ClickTrends summarizes the LocaliQ numbers by industry. For Meta, Triple Whale’s benchmark report found a median CTR of 2.39% across more than 40,000 brands between August 2025 and July 2026, ranging from about 1.9% to 3.0% by industry.
Last verified: October 2026.
The best benchmark is your own. Compare each ad with your other ads on the same channel and with your own average from the past few months.
CTR in SEO and Google Search Console
CTR also matters for organic search. In Google Search Console, CTR is the percentage of people who saw your page in the results and clicked it. It’s clicks ÷ impressions, the same formula.
Your CTR in search depends on where you rank, how your title and description look, and whether the results page has features like ads, AI summaries or snippets that take attention. A better title and description can lift CTR without changing your ranking.
CTR and your other ad numbers
CTR sits in the middle of the ad chain:
- You pay for impressions at a price called CPM.
- Some people click. That share is your CTR.
- Some clicks turn into customers. That’s your conversion rate.
- Revenue comes in, and you can measure it with ROAS.
Raise your CTR and you get more clicks from the same impressions. Your cost per click falls, as in Example 5.
How to improve CTR?
- Write a clearer headline. Say exactly what the person gets.
- Match the ad to the search or the audience. A relevant ad gets clicked more.
- Test one change at a time. Change the headline, then the image, then the offer. Otherwise, you won’t know what worked.
- Use a strong, specific call to action. “Get the free checklist” beats “Learn more.”
- Narrow or refine the audience. Showing an ad to the wrong people drags CTR down.
- Check your ad format and placement. The same ad can do very differently in a feed and on a sidebar.
A caution: chasing CTR alone can backfire. A misleading or clickbait ad can get plenty of clicks and no sales, so you pay for visits that don’t convert.
CTR vs conversion rate
| CTR | Conversion rate | |
|---|---|---|
| Formula | clicks ÷ impressions | conversions ÷ clicks |
| It tells you | how appealing the ad is | how well the landing page turns clicks into customers |
You need both. A high CTR with a low conversion rate often means the ad promises something the page doesn’t deliver.
Common CTR mistakes
- Judging an ad on too few impressions.
- Mixing “link clicks” with “all clicks”, or using different date ranges.
- Comparing CTRs from different channels as if they were the same thing.
- Celebrating a high CTR without checking conversions.
- Forgetting that email CTR can be measured against emails delivered or against emails opened. Check which one your tool uses.
CTR calculator FAQ
How do you calculate CTR?
Divide clicks by impressions and multiply by 100. For 250 clicks and 10,000 impressions, CTR = 250 ÷ 10,000 × 100 = 2.5%.
What is a good CTR?
It depends on the channel and industry. Reports put Google Search ads anywhere from about 3% to 6.6%, Google Display ads near 0.5%, and Meta ads around 2.4%. Compare your results with your own past ads.
What does a low CTR mean?
It usually means the ad isn’t relevant enough to the people seeing it. The headline, the offer, the image or the audience may need work.
How many impressions do I need for a reliable CTR?
There’s no fixed number, but a few hundred impressions is a bare minimum and a few thousand is better. With very few impressions, a single click can swing the result.
What is the difference between CTR and conversion rate?
CTR is the share of people who click after seeing your ad. Conversion rate is the share of clickers who then buy, sign up or take another action.
How does CTR affect cost per click?
At the same CPM, a higher CTR gives a lower cost per click. CPC = CPM ÷ (1,000 × CTR as a decimal).
Is a high CTR always good?
No. A high CTR with no sales can mean the ad attracts the wrong people or promises too much. Look at conversion rate and cost per acquisition as well.
How this calculator works?
The calculator uses the standard definition of click-through rate and runs entirely in your browser, so nothing you type is sent anywhere. I test every result against hand-calculated examples. See How We Calculate for how I test and update the tools. Results are estimates based on the numbers you enter. They aren’t financial advice.
