- ctr (click-through rate)
- 0.85%
- clicks ÷ impressions
- 850 ÷ 100,000
inverse, what you need to hit a target ctr
- clicks needed for 1.5% ctr
- 1,500
- impressions needed for 1.5% ctr
- 56,667
> worked example
Your email campaign delivered 100,000 impressions and received 850 clicks, giving a CTR of 0.85%. Industry benchmarks for ecommerce display sit around 0.35%, so this is above average, but a paid search ad at 0.85% would signal a poorly written headline. Using the inverse: to hit a 1.5% CTR with 100,000 impressions, you need 1,500 clicks. Alternatively, if you know you'll get 850 clicks and want a 1.5% CTR, you need to limit distribution to roughly 56,667 impressions, useful for targeting a tighter segment.
takeaway, CTR sets the quality floor; if yours is low, more impressions just buys more irrelevance.
