Wait, how does one website (google.com) know what happens inside my browsing session on another website (bad-blog.com) after I click over? Hmmmmm
This sort of announcement just emphasizes the extent to which Google observes ALL your web browsing behavior, thanks primarily to their eyes inside Chrome browser.
You know those warnings when you install a browser extension, about all the things that extension will be able to see and do? Well so can Chrome itself…
They likely scan the web pages themselves, but you shouldn't be using Chrome anyways, if you care about privacy from Google.
They've been crawling the web since inception
