My website uses flexible sampling to limit the number of free articles unregistered users can view. I use fingerprint tracking to keep track of which customers have reached their monthly view limit. When doing fingerprint tracking, I also check whether the useragent is Googlebot and if it is, I will give it full access to crawl my website.
However, I have seen a few articles (like this one) saying that Google is against fingerprint tracking. I wonder if I use fingerprint tracking, does Google punish my website's search ranking? If it does, I probably need to switch to cookie tracking.
