The main takeaway is that Google uses Chrome to collect data on what search results people click on and how long they spend on those pages. They then use that data to rank search results.
Ah, I see. That makes sense, but to be fair I think that was expected. I suspect they also pull the same data from every page where adsense is embedded regardless of browser, e.g., and every other company out there is aggregating the same sort of data every possible place they can get it from (shared sign ins, etc etc)
Edit: Itβs definitely a particularly bad look when there are several things in there that representatives for Google have apparently lied about over the years.
