However we do know it is a factor, to what degree will be the question, but the bigger factor is what that CTR leads to. You can have a high serp CTR but a super high bounce rate and in that case CTR is not going to do much for you. Right? So CTR is just one little factor it’s more about what happens next. I assure you that counts a lot more than just CTR.
How much of a difference does CTR make with GMB rankings? I’ve done all of the other optimizations, photos, citations, map embeds, Etc.
No one can answer this question 100% for certain, unless you get a Google insider to talk to you..
