Basic

What it is & how to use it

Click-through rate (CTR) is the share of impressions that result in a click. It helps compare creative and query relevance.

How to use the CTR Calculator

1) Enter clicks.
2) Enter impressions.
3) Read CTR as a percentage.
4) Keep the same placement and date range when you compare creatives.

Intermediate

Formula & worked example

CTR = (Clicks ÷ Impressions) × 100.
Worked example: 250 clicks ÷ 10,000 impressions = 2.5% CTR.
CTR cannot exceed 100% with valid inputs.

Advanced

Interpretation, edge cases & next steps

High CTR with poor conversion still fails the business case.
Advanced: segment by device, match type and audience; pair CTR with CPC and ROAS. Benchmarks vary heavily by channel — use your history.
Planning estimate only.

How do I improve CTR?

Tighten relevance, creative and targeting — then re-measure in the same window.
