CTR = clicks ÷ impressions × 100How to use the result
CTR shows how often an impression becomes a click.
Click-through rate helps compare how effectively an ad, keyword, listing or message earns clicks. It does not show whether those clicks became qualified leads, sales or profitable customers, and a useful CTR varies by channel, format, audience and intent.

CTR calculation example
If an advert receives 1,250 clicks from 50,000 impressions, its CTR is 2.5%. That result describes the click response only; conversion rate and cost data are still needed to judge business performance.
Common mistakes to avoid
- Combining clicks from one date range with impressions from another.
- Comparing Search, Display, paid social and email CTR as if the formats have the same intent.
- Treating a high CTR as proof that the traffic converts or produces profit.
- Ignoring low-volume data, accidental clicks, brand traffic and audience differences.
Frequently asked questions
CTR calculator — click-through rate calculator FAQs
What does CTR mean?
CTR means click-through rate. It is the percentage of recorded impressions that resulted in a click.
How do you calculate click-through rate?
Divide clicks by impressions and multiply by 100. For example, 50 clicks divided by 2,000 impressions equals a 2.5% CTR.
What is a good click-through rate?
There is no universal good CTR. Compare performance within the same channel, format, audience, market and intent, then check whether the clicks create valuable outcomes.
Can I calculate required clicks from a target CTR?
Yes. Select Clicks, then enter impressions and the target CTR. The result is a planning estimate rather than a performance guarantee.
Does a higher CTR reduce Google Ads costs?
CTR can contribute to expected CTR and relevance signals, but actual costs depend on the auction, bidding, competition, ad quality, context and other factors. CTR alone does not determine CPC.
