Sometimes I'm getting good traffic and sometimes i'm not getting enough traffic. I don't know why it happening like this. Can any one give me some suggestion.
Traffic volume seems to vary quite significantly from day to day but I am doing more with them than anybody else right now (Yahoo 2nd & very liitle with G now after numerous 'QS update' slaps.)
I have been using both Adcenter and Adwords and my results show that Adcenter beats the daylights out of Adwords in ROI/Conversions. I can attribute this mainly due to NO search partner network/content network present within Adcenter. So Adcenter provides top quality pure traffic from within its own network. It does not place your ads on any search partner sites or on any 3rd party websites. Adcenter is a dream come true. These guys are willing to talk for an hour on the phone to answer your questions irrespective of whether you are a big/small advertiser. At this rate, if their search volumes increase, Adcenter can very well be poised to give Adwords a tough time. These days I have to turn off the Adwords content network to save my campaigns from being flooded with 80% non converting traffic from publisher websites.
I do best with MS and Yahoo. Get way more traffic from Google, but it's at a higher price and much of it is crap!
