I know it is highly website-dependent, but is there any statistics/study/report on the ratio of real visitors websites get and the visits made by the search engine crawler?
Services like Alexa reports an estimate of visitors and views a website received. I look for the same sort of information but also by considering the crawler visits (most importantly GoogleBot).
Specifically, I am interested in the ratio of Googlebot visits and the traffic websites received from Google Search Results. It is obviously available to webmasters through Google Search Console. I hope to find some public data (estimations, of course).
