> Does anyone really appreciate searching on Google for a vacuum cleaner and then seeing photos of vacuum cleaners follow them around all over the web for months afterwards? Is this really google selling this information? I assumed that the people selling this information gathered it from the referrer links after you click on the search result. Any of those pages can have JavaScript running that picks out your google search term from the referral link. The reason the distinction matters is they can get the same referral string from your DuckDuckGo searches if they want to bother.
