I'm putting together some promo material and wanted to get some stats to answer this question. According to a study from a company called Optify, the CTR for top three organic positions are:
- No. 1: CTR of 36.4 percent
- No. 2: CTR of 12.5 percent
- No. 3: CTR of 9.5 percent.
Attached is a copy of Optify's research report.
