Click-Through Rate (CTR)
The percentage of users that click on something. Often used in advertising to measure how many people click an ad, but SEOs often refer to the clicks they get from Google's result page.
The higher your ranking in Google, the higher you can expect the CTR to be: more people click the number 1 result vs. the number 3 result, and virtually no one clicks the results beyond page 1.
The CTR curve tells you the click-through rate for all positions on the SERP.Back
