This is due to a thing called cookies. https://en.wikipedia.org/wiki/HTTP_cookie

Logging out of an account won't stop your search history from being used to create ads targeted towards what you have searched via the browser.
To clear that information, you need to clear your cookies and cache from your browser.
You can block some types of cookies in your browser setting, just be aware that some cookies are essential and this can interfere with some website actions, or result in things like perpetual sign in loops.
You can also open a private tab or window in most browsers and anything you do in that tab will not be stored in your browser's history.
