I guess DP ads has very less inventory I hardly find a site which is displaying quality ads with dp adcodes. i ran these codes for few days but found them making my webpages load very slow. adsense or any other ads load much quicker If i can find atleast 100 sites which run dp adcodes and found quality advertisers, then i would consider using these codes again
There's *no* "inventory"... it's a prepay system where advertisers pay the site owner to run ads specifically on your site. If there are 10,000 sites all running ads it wouldn't matter if no advertisers are interested in displaying ads on your site specifically.
that means there're hardly any advertisers here. most important is slowness these adcodes causes. insert adsense and dp ads on same page and test for yourself.
There are a ton of advertisers of advertisers... there are a little over 5,000 different *paying* advertisers advertising just on digitalpoint.com for example. But the bottom line is the system isn't a way to *get* advertisers, it's a way to sell advertising space to advertisers you already have.
