In a nutshell please explain me how and what are the algorithm an adserver works. i know the simple working procedure ie, picks up the best relevant ads from a list of ads and displays accordingly, yet saying relevant ads isnt enough to explain its procedure, If i want to implement something like that in php programming how should i take the things, just do a match and display , shuffle the ads and display or display as per the advertisers $$. or what ... These things are confusing me. If you were to build a scalable ad server, interms of happy advertisers how will you code it in php . saying happy advertisers coz such situations arises when it collides between a targetted campaign advertiser and a global targetted advertiser. Acccording to algorithm both ads are eligible to be viewed by a normal user. Discriminating anyone of them makes them withdraw service from me. So please answer keeping this complicacy.
Too much of questions , sorry, but just curious,
