Website targeted advertising...how does it work?
The other day I was looking on JL: website and looked at some bathroom scales (yes yes post -Xmas excess!) and television bargains. Today I look at a completely unrelated website and between articles there is an advert that flashes up from JL with the exact same scales and TVs I was looking at.
Clearly somewhere there is a catalogue of my browsing history or something but could someone explain or point me in the right direction to understand the specific process/technology behind it. It's very clever but a bit creepy too!
