When users click on the URL in their email, they are directed to a private page on my website, and their username and IP address is logged. However, I noticed that when the user is a Gmail user, their IP address is always followed by a Googlebot-IP address (confirmed with whois). It appears that the Googlebot follows Gmail users when they click on links in their emails. I wonder, what does it do with this information? Is it used only for Gmail-advertising, or are these pages that I've intended to be private and unique being indexed by Google? Has anybody else experienced this?"
