Fill in one side to find the missing number needed to hit a target CTR.
CTR = clicks / impressions x 100.
Click-through rate (CTR) tells you what share of the people who saw your link, ad, or listing actually clicked it, calculated as clicks divided by impressions times 100. Enter impressions and clicks below for an instant CTR percentage, or use the goal calculators to work out how many clicks or impressions you need to hit a target CTR.

What is the CTR Calculator?
Click-through rate is one of the oldest and most useful metrics in digital marketing because it measures relevance in a single number. Whether you are looking at a Google Ads campaign, an organic search listing in Google Search Console, a marketing email, or a display banner, CTR answers the same question: out of everyone who was shown this, how many cared enough to click? A high CTR usually means your headline, thumbnail, ad copy, or subject line is doing its job. A low CTR is a signal, not a verdict, but it is almost always worth investigating.
The formula behind CTR is deliberately simple. You take the number of clicks a link, ad, or search result received, divide it by the number of impressions (the number of times it was shown), and multiply by 100 to express it as a percentage. Impressions must be greater than zero for the calculation to make sense, since you cannot divide by zero, and clicks should logically never exceed impressions in a well-tracked system, though tracking discrepancies between platforms sometimes produce numbers that look odd at first glance.
What counts as a "good" CTR varies enormously by channel and context. A Google Ads search campaign in a competitive niche might see CTRs in the low single digits and consider that healthy, while a branded search campaign for your own company name can easily clear 30 to 40 percent. Organic search CTR depends heavily on ranking position, a listing at position one on Google typically earns a much higher click-through rate than the same listing at position eight, even with identical title and description. Email marketing CTR is usually measured against total recipients or against opens, and email benchmarks sit far lower than search or ads, often in the low single digits, because clicking a link inside an email is a bigger commitment than clicking a search result.
Because CTR is a ratio, it can mislead if you look at it in isolation. A campaign with 50 impressions and 5 clicks has a 10 percent CTR, the same as a campaign with 50,000 impressions and 5,000 clicks, but the second number is statistically far more reliable. Small sample sizes produce volatile CTR figures that swing wildly with one or two extra clicks, so always weigh CTR alongside impression volume before drawing conclusions or making budget decisions based on it.
When to use it
- Checking the click-through rate of a Google Ads or Microsoft Ads campaign from raw impressions and clicks.
- Analyzing an organic search listing pulled from Google Search Console to see how it compares to position benchmarks.
- Measuring email marketing performance by calculating CTR from send count or open count against link clicks.
- Working backward from a target CTR to figure out how many clicks a campaign needs to hit its goal.
- Working out how many impressions (or how much ad spend, via impression volume) are needed to generate a required number of clicks.
- Comparing CTR across two versions of an ad, headline, or thumbnail in an A/B test.
How to use the CTR Calculator
- Enter the total number of impressions your link, ad, or listing received.
- Enter the total number of clicks it received over the same period.
- Read the calculated CTR percentage instantly in the results box, and copy it if needed.
- Optionally, use the goal calculators below to solve for the clicks or impressions needed to hit a target CTR percentage.
Formula & method
Worked examples
A blog post gets 10,000 impressions in Google Search Console over 28 days and earns 250 clicks. What is its CTR?
- Identify the inputs: impressions = 10,000, clicks = 250.
- Apply the formula: CTR = clicks / impressions x 100.
- Divide: 250 / 10,000 = 0.025.
- Multiply by 100 to convert to a percentage: 0.025 x 100 = 2.5.
Result: CTR = 2.5%, meaning 1 in every 40 people who saw the listing clicked through to the page.
A Google Ads campaign has run 1,200 impressions and needs to hit a 4% CTR to satisfy an internal benchmark before scaling budget. How many clicks does it need, and does it currently have enough?
- Use the goal formula: Clicks needed = Impressions x (Target CTR / 100).
- Plug in the numbers: 1,200 x (4 / 100) = 1,200 x 0.04.
- Calculate: 1,200 x 0.04 = 48.
- Round up if the result is not a whole number (here it already is): 48 clicks required.
- Compare to the actual click count. If the campaign currently has exactly 48 clicks on 1,200 impressions, it is sitting exactly at the 4% target.
Result: The campaign needs at least 48 clicks on 1,200 impressions to reach a 4% CTR.
Typical CTR benchmarks by channel (industry averages, actual results vary widely)
| Channel | Typical CTR range | Notes |
|---|---|---|
| Google organic search, position 1 | 25% to 35% | Highest CTR of any organic position, drops sharply after position 3 |
| Google organic search, position 5 to 10 | 1% to 3% | Most traffic still concentrates in the top 3 to 5 results |
| Google Ads search network | 2% to 6% | Varies heavily by industry, keyword intent, and ad relevance |
| Branded search campaigns | 25% to 40%+ | Users already searching for your exact brand name convert to clicks easily |
| Display or banner ads | 0.3% to 0.9% | Lowest CTR range, treated more as a brand awareness metric |
| Email marketing (click-to-open rate) | 2% to 5% | Measured against opens rather than sends in most reports |
| Social media ads (feed placements) | 0.5% to 1.5% | Varies by platform, format, and targeting precision |

Common mistakes to avoid
- Comparing CTR across channels without context. A 2% CTR is mediocre for organic search position 1 but excellent for a display banner ad. CTR only means something when compared to the benchmark for its specific channel, format, and position, never as a single universal target.
- Judging CTR from a tiny sample size. Five clicks on twenty impressions produces a 25% CTR, but that number will swing enormously with the next few impressions. Wait for a meaningful volume of impressions, generally at least a few hundred, before trusting a CTR figure enough to act on it.
- Confusing CTR with conversion rate. CTR measures whether people clicked, not whether they bought, signed up, or completed any goal after landing. A high CTR with a low conversion rate usually points to a mismatch between the promise in the ad or title and what the landing page actually delivers.
- Ignoring which base impressions are counted against. Email CTR reported against total sends looks very different from CTR reported against opens only, and the two are not interchangeable. Always check which denominator a report is using before comparing CTR figures pulled from different tools or platforms.
Glossary
- Click-through rate (CTR)
- The percentage of people who clicked a link, ad, or listing out of everyone who saw it, calculated as clicks divided by impressions times 100.
- Impression
- A single instance of a link, ad, or listing being displayed to a user, whether or not they clicked it.
- Click
- A recorded instance of a user clicking a link, ad, or listing after it was shown to them.
- Click-to-open rate (CTOR)
- In email marketing, the percentage of people who clicked a link out of those who opened the email, rather than out of total recipients.
- SERP position
- The rank at which a page appears in search engine results, a major factor in organic CTR since higher positions receive disproportionately more clicks.
- Quality Score
- A metric used by ad platforms like Google Ads that factors in expected CTR, ad relevance, and landing page experience to influence ad rank and cost.
Frequently asked questions
What is a good CTR?
It depends entirely on the channel. For Google Ads search campaigns, 2% to 6% is typical, while organic search results in position 1 often see 25% to 35%. Display and banner ads sit far lower, often under 1%. Compare your CTR to benchmarks for your specific channel and position rather than a single universal number.
How do I calculate CTR?
Divide the number of clicks by the number of impressions, then multiply by 100. For example, 250 clicks on 10,000 impressions gives 250 / 10,000 x 100 = 2.5%. This calculator does the division automatically once you enter both numbers.
Why is my CTR low even though my ad or page ranks well?
Ranking or ad position and CTR are related but not the same thing. A well-positioned ad or listing with a weak headline, unclear value proposition, or unappealing thumbnail can still underperform its position. Test different titles, descriptions, or ad copy while keeping position and targeting constant to isolate the real cause.
Does a higher CTR always mean a better campaign?
Not on its own. CTR measures interest, not outcome. A campaign can have a strong CTR but a weak conversion rate if the click does not lead to a sale, signup, or other goal. Always look at CTR alongside conversion rate and cost per acquisition before judging overall performance.
How many impressions do I need for a reliable CTR?
There is no fixed threshold, but CTR calculated from fewer than a few hundred impressions tends to be volatile and can shift a lot with just a handful of extra clicks. For campaigns or pages with low traffic, treat early CTR figures as provisional and revisit them once impression volume grows.
Can CTR be over 100%?
No, not in a properly tracked system, since clicks cannot logically exceed impressions. If you ever see a CTR figure above 100%, it usually indicates a tracking or attribution issue, such as clicks being counted from a different date range or source than the impressions.
