And it must be targeted. Using AdBrite at the moment but it only makes me 10c a day if I'm lucky and that's across a few websites. So any others worth trying?
You can try the ppc network in my sig, they're great. Not picky about traffic and will let you pick your keywords, so you can pick the high paying ones and earn loads.
alternateurl.com - you choose the keywords for your site. elementads.com - you choose the keywords for your site. bannerboxes.com - category based adster.com - similar to adbrite, clicks seem to pay a bit more though.
I recommend Exoclick too - particularly useful if you have a site with gambling/adult related content which isn't permitted by some of the bigger players. Also handy from the point of view that you get paid by PayPal and there's a fairly modest minimum payout level. If you're running a site with very widespread content (like porn) then you aren't going to get much per click unfortunately. If you fancy something a little different you can read my review on Text Link Ads. TLA also pay by PayPal.
Bidvertisor is a waste of cyberspace. Don't even bother with them. I tried them for one day, and recieved about 50 mysterious '0.00' clicks. 3fnppc is pretty good, though they never accepted me, for some strange reason. I just didnt get a response from them. Quoted for truth. Exoclick is one of the best new ppcs, and they have some attractive features.
Strange. I have been using Bidvertiser for nearly two weeks and the CPC is not bad at all. The CTR goes lower than I expected but not that bad. I earn much better than 3fn or Kontera with Bidvertiser.
I expect you'll see this decline with time. When I first started using them I thought they were pretty darn good too, but as time went on, less and less clicks were counted, epc dropped. Dunno why, but they just seem to degrade the longer you use them.
