What Is CTR (Click-Through Rate)?
Click-through rate is the percentage of people who see something and click it. An impression is one time your ad, link, email or thumbnail is shown. A click is one time someone interacts with it. CTR tells you how well your message gets people to take the next step, which makes it one of the most used measures in advertising, SEO and email marketing.
CTR Formula
CTR (%) = (Clicks / Impressions) x 100
Divide clicks by impressions and multiply by 100 to turn the decimal into a percentage. For email, use delivered emails instead of impressions, and for some reports use opened emails instead. Always state which base you used.
Worked examples
| Case | Clicks | Impressions | CTR |
|---|---|---|---|
| Display ad | 500 | 5,500 | 9.09% |
| Search ad | 45 | 3,000 | 1.50% |
| Email campaign (delivered) | 38 | 2,500 | 1.52% |
| Blog title in search results | 120 | 8,000 | 1.50% |
For the first row: 500 divided by 5,500 is 0.0909, and 0.0909 times 100 is 9.09 percent.
Reverse formulas
- Clicks = Impressions x (CTR / 100). At 1.25 percent CTR, 10,000 impressions give 125 clicks.
- Impressions needed = Clicks / (CTR / 100). To get 200 clicks at 2 percent CTR, you need 10,000 impressions.
What Is a Good CTR?
There is no single good CTR. It depends on the channel, the industry, the audience, the offer and, in search, the position of the result. A CTR that is excellent for a display banner can be weak for a branded search ad. Compare your result with your own past results and with data from your industry, and use an outside benchmark only as a rough guide.
| Channel | What CTR depends on | Rough guide |
|---|---|---|
| Search ads | Keyword intent, ad position and brand | Often a few percent. Branded terms are far higher |
| Display and banner ads | Placement, format and audience | Usually well under 1 percent |
| Subject line, list quality and what the base is | Often 1 to 5 percent of delivered | |
| Social posts and ads | Platform and creative | Usually a few percent or less |
| Organic search results | Ranking position and the results page layout | See the position table below |
These are broad ranges, not firm benchmarks. Published averages differ between studies and years, so use them as context and not as a target.
CTR by Google Search Position
In organic search, a result in the top position gets far more clicks than the rest. This is the click-through rate curve seen in keyword tool data for one sample search, taken from Mangools SERP data for the keyword "ctr calculator" in the US. Real values change by search, device and the features on the page.
| Position | Example CTR | What it means |
|---|---|---|
| 1 | About 29.8% | Nearly three in ten searches click the top result |
| 2 | About 12.5% | Less than half the clicks of position 1 |
| 3 | About 6.7% | Halves again |
| 4 | About 4.2% | Small but steady |
| 5 | About 2.8% | Under a third of position 2 |
| 6 | About 2.1% | Lower half of the first page |
| 7 | About 1.5% | Few clicks reach this far |
| 8 | About 1.2% | Last of the top eight |
The lesson is that moving from position 3 to position 1 can multiply your clicks several times, and that a better title and description can lift CTR at the same position.
How to Improve Your CTR
- Search results: write titles that match the search and promise a clear benefit, and write meta descriptions that give a reason to click. Use the number or year only when they are true and useful.
- Ads: put the main keyword in the headline, add a clear offer and a strong call to action, and use all the extensions the platform allows.
- Email: test subject lines, keep them short and specific, and send to people who asked to hear from you.
- YouTube and social: use a clear, high contrast thumbnail and a title that says what the viewer gets.
- Relevance: show the right message to the right audience. A tighter audience usually means a higher CTR.
- Test one change at a time and wait for enough impressions before you decide.
Compare Two Ads: Is the Difference Real?
Say Ad A got 120 clicks from 8,000 impressions, a 1.5 percent CTR, and Ad B got 168 clicks from 8,000 impressions, a 2.1 percent CTR. Ad B is 0.6 percentage points higher, which is 40 percent better in relative terms. But with small numbers, chance can look like a winner. As a rule, wait until each version has hundreds of clicks, and use a proper significance test before you make a big decision. The Compare tab shows both CTRs and the gap, and warns you when the sample is small.
CTR vs Conversion Rate vs Other Metrics
| Metric | Formula | What it tells you |
|---|---|---|
| CTR | Clicks / impressions | How well your message gets clicks |
| Conversion rate | Conversions / clicks | How well your page turns clicks into actions |
| CPC | Cost / clicks | What each click costs |
| CPM | Cost / impressions x 1,000 | What 1,000 impressions cost |
| Open rate (email) | Opens / delivered | How well your subject line gets opens |
A high CTR is only good if the clicks lead somewhere useful. Always read CTR alongside conversion rate and cost.
Common CTR Mistakes
- Mixing up time periods. Use clicks and impressions from the same dates.
- Using total clicks and unique impressions, or the reverse. Keep the same base on both sides.
- Judging a result with too little data. A handful of clicks says very little.
- Comparing different channels. A banner CTR and a search ad CTR are not comparable.
- Chasing clicks only. A misleading title can raise CTR and hurt conversions and trust.

FAQs
How do I calculate CTR?
Divide the number of clicks by the number of impressions, then multiply by 100 to get a percentage. For example, 45 clicks from 3,000 impressions is 0.015, which is 1.5 percent. Use clicks and impressions from the same period and the same ad, page or email so the result is fair.
What is a good click-through rate?
It depends on the channel, industry and audience. Search ads often get a few percent, display banners usually get well under 1 percent, and email often falls between 1 and 5 percent of delivered. Compare your CTR with your own past results first, and treat outside averages as rough context only.
What is the difference between CTR and conversion rate?
CTR is clicks divided by impressions, so it measures how many people who saw something clicked it. Conversion rate is conversions divided by clicks, so it measures how many people who clicked went on to buy or sign up. You need both to judge whether a campaign really works.
How do I calculate clicks from impressions and CTR?
Multiply impressions by CTR as a decimal. At a 2 percent CTR, 10,000 impressions give 10,000 times 0.02, which is 200 clicks. To go the other way, divide your click goal by the CTR as a decimal to find the impressions you need. The calculator has a tab for each.
What is a good CTR for Google organic search?
It depends on position. In sample keyword tool data, the top result gets roughly 30 percent of clicks, position 2 about 12 percent and position 3 about 7 percent, falling quickly after that. Your own CTR also depends on your title, description, brand and the features on the results page.
How can I improve my CTR?
Write a clear, specific title and description or headline, match the search or audience intent, and use a strong call to action. For email, test subject lines. For video and social, test thumbnails. Change one thing at a time, and wait for enough impressions and clicks before you pick a winner.
How many impressions do I need to trust a CTR?
There is no fixed number, but more is better. With only a few hundred impressions, a couple of clicks can swing the result a lot. As a rough rule, wait for each variation to reach at least a hundred clicks, and use a significance test for important decisions.
Is my data safe in the calculator?
Yes. All calculations happen in your browser. Your clicks, impressions and results are not sent to a server or stored, so you can use real campaign numbers. Close the tab and the numbers are gone, so copy any result you need to keep.
