some of the targeted ads I've seen on here and other forums recently are quite clever. for example, I've got a new shed coming tomorrow, so I often see ads for sheds & other garden buildings; I'm a big fan of New Model Army, so to see ads for their new album is not entirely surprising
however, I've just seen an ad in German. I'm not German, nor in a German speaking country, nor have I ever been to one, so why the German language ad?
this is the clever bit...
several hours ago, on my work laptop - not my home PC wot I'm using now - I used google translate to get the German equivalent of "Delivery Date". "Lieferdatum".
