I am finding a lot of sites have VERY targetting advertising.
It is as if my internet habits have been analysed and this information is used to make adverts appear. So far I have noticed this on hotmail and several other sites.
For example, just before Christmas I found a lot of websites had adverts for the fashion store Warehouse (which I had been on looking for a dress). It even used pictures of the dresses I had viewed but not bought in the advert.
Today I have been on Boots and ASOS (cosmetics and fashion respectively) and now I am finding other websites are advertising these heavily. Once again the ASOS adverts are including dresses I have viewed (they are thousands of dresses on this site so it would be VERY good luck that it is a coincidence).
How are they doing this??
