There are many advertising networks which provides Full Page ads. But if you consider as per the visitor`s view. The Full Page ad frustrates a visitor. The first thing a visitor does is he/she searches for the "Skip this Ad" Button. Now this point should be noted down or should be considered by any webmaster.
The Publisher should not opt these kinds of ads. Though you must be getting good CPM rates. But the traffic will be lowered down gradually. If the traffic goes down then whats the point in putting these ads even if you are getting high CPM rates? Full page ads are killing your web traffic. So what should be done. You should avoid putting the Pull Page Ads to any blog. For example if you consider the link based advertising company adf.ly If you click any of their link then you will get to visit a whole page of ad and you got to wait to get the ad skipped. So this is really irritating to any visitor and he/she will make sure that they will not visit your site again unless and until there is some useful stuff in there for them. So avoid Full page ads and use banner ads and other ad methods. Happy Blogging for Webmasters!
