Click-through rate is the percentage of people who click after seeing your ad or search listing. The formula: CTR = clicks divided by impressions, times 100. If your ad shows 10,000 times and earns 350 clicks, that is 350 / 10,000 x 100 = 3.5% CTR. The calculator above runs the math instantly, benchmarks the result, and adds CPC and reverse-projection math so you can plan campaigns, not just grade them.
"Good" depends entirely on the channel. A 1% CTR is weak for a search ad and excellent for a display banner. Here is what widely published benchmark data shows:
| Channel | Typical CTR |
|---|---|
| Google Ads, search | 3-6% average (WordStream benchmarks) |
| Google Ads, display | ~0.5% |
| Email marketing | 2-3% of delivered emails |
| Organic result, position 1 | ~27% (CTR studies) |
| Organic results, positions 2-3 | ~8-16% (CTR studies) |
The organic numbers explain why ranking matters so much: position 1 typically gets several times the clicks of position 3, and ten times or more the clicks of anything on page 2.
For organic search, better CTR compounds with rankings: a listing that earns more clicks than its position predicts tends to keep climbing, and every position gained raises CTR again. We saw this loop in action with LiveHelpNow, a live-chat SaaS platform, which added over 3,000 organic visits a month as titles, snippets and rankings improved together.
