It’s scary how much they know about you or can assume based on your online activity.
Google have their own advertising platform where they sell space. So I can go to Google and tell them to show my ad to people who like pizza, who live in West London, drive a car, earn over £40k, own their own home and be really specific. It’s insane how much (and accurate) information these companies have on you, and for those areas they don’t cover, it can be layered together from other sources who sell your information too.
You can dig a little into how much they know about you and try restricting some of it here:
- Go to your Google Account.
- On the left navigation panel, click Data & personalization .
- Take a look at the ad personalisation part. You’ll see it knows your age, interests, marital status, where you shop, devices you use, if you drive and so on…
You might as well drill through the other sections on this page to try and restrict things further too
