There are only 2 things that'll increase Adbrite earnings 1) Placement 2) Traffic What forums? He didn't mention forums
oh my god bad ad placement,make ads background same as ur site background,put one ad between the posts.
lol my adsese account gives me 0.01 everyday even with no clicks... Anyway, The best things you can do is change the placement of your ads, and change how they look. Make them blend in with your site. Have the same color links as your links, and the same background. If your using them on the Anime site in your sig, good luck. Young people that watch anime for free on their computers don't click on ads unless you trick them into it. Ive had no real success with any anime sites in the past. No clue how some people do it. But my recommendations above work on all my other sites.
