Why are the things I'm watching on my laptop displayed to my parents on the PC as advertisements?

I have a question: I often look at things on my laptop. Clothes or something. I then put the things in the cart and recently I noticed that the things I look more often my parents are displayed as advertising. Why is that?

Because you use the same router and thus the same IP, so Google and co think you are one person and you are almost confused.

Oh thanks
