Google shows you ads based on your movements on the net. For many years, users have also been shown how to assess them.
This is done under adssettings.google.com. There you know what Google “thinks” of you and on what basis you get advertising about Google’s networks.
This does not necessarily have to fit like a fist to the eye, which is why you can also activate what you want to see less on the page.
An excerpt of what Google thinks about me, you can see above this paragraph. Audi is absolutely not suitable for me, I could also deselect that from Google.
