What is the best way to count unique visitors?

Question

Web traffic analysis

How to make a high-quality count of uniques? According to Google analytics or i.metrica. I know a good ip + cookie option, maybe someone had experience? Share..

Answer 1

Solved the problem myself! Ya.metrica and G.analysts do this: they insert a tag into the body of the site, in the src of which the url is inserted at which the visitor is recorded and all the necessary parameters are passed (os, device, browser, etc.) and a transparent one is rendered at this url picture 1px by 1px. If the visitor is a bot, then he cannot execute js, which means that the tag will not be inserted into the body of the site and thus the visit will not be recorded.
