Yesterday I started with clickexa and when I implemented the ads code in my blog it shows Google ads that means he is using google ads and serving the same ads to us. Also another thing is when I displayed one slot of 336 x 280 of clickexa ads, I lost my one other ads slot as by google. Is it the same thing with you guys?
I think the admin of clickexa sent emails asking not to use his codes until further notice... It is in beta and they are experiencing some technical difficulties Check your SPAM mails .... it was there ..... i noticed it when i was about to clear my spam..
