Shortly after Brexit went into effect, some surprising advertisements began to haunt me on a social network. They were from a British police force, encouraging me to come forward for their selection processes. Opposition announcements aren’t exactly new to my feed (I feel like Instagram advertising is convinced I’d be a lot happier if I took on a librarian), but this one was especially striking because in the context we were in it made Kuwait Mobile Database a lot less sense . What was I, a community citizen sailing from an EU country, painting in targeting to receive messages to become a British policeman? British ads have continued to appear since then on my feed, especially on Twitter, and I am not the only one in my circle who occasionally gets messages intended for that audience. They have tried to tell a friend what to do as a British citizen living in an EU country (my friend lives in the EU, but she is not a British citizen). The how and why segmentation leads to this is surprising in an age where companies know too much about you. 
The promised benefits of online advertising and its segmentation based on data have been repeated over and over again over the last few years and have become an almost unquestionable element of wisdom. Segmentation using the large amounts of data that we have allows to profile the market Brother Cell Phone List niches in a highly realistic way, consumers are being reached with what they really want and they are known so well that it is possible to go beyond the stereotypes about consumption patterns. The big question, or that is what the FT column invites to ask , is whether this is all real or if it has a lot of smoke. As the columnist points out, we have all been haunted by nonsense ads that had little to do with our interests or our states in life.
And, when you go to see what the different web services that interest you consider, it is not difficult to find errors or questionable interests (Facebook, for example, believed that it is very interested in greeting cards, but as few people point out he has them as an element of passion; he has as an element to serve me ads that interest me rhinos, which is possibly a follow-up error because what interests me is the publishing house Rinoceronte). Therefore, and without denying that for citizens having more control over their online privacy is a necessity and something key, it would be necessary to ask, from the point of view of advertisers, if the segmented advertising offered by the network giants is so effective in creating niche markets, notes the column, as it is selling.
A study a few years ago on behavior patterns on eBay could agree with those who agree with this approach and believe that programmatic advertising is far from being Jauja. The study, conducted by researchers at the University of Berkeley, used eBay listings as a benchmark. They wanted to check whether or not they were effective in making the products sell. After pausing advertising on eBay’s Google Search for three months for a control group, they found that there was only a minimal difference in sales. The ads had been serving simply to target consumers who were already hoping to buy that product.
