I am thinking about converting my vbulletin forum to an IPB one, honestly i find Invision more advanced, more options, more upgrades, more new options, .. real evolution i find !
so i was wondering if i convert it i will surely loose some trafic, but for adsense eCPM i am not sure ! that will take more time purhapse ?

I honestly would not leave vBulletin but everyone has their preferences.
i have a small forum and my members are not very experimented in using forum and i found IPBoard just simple to use, i like their Nexus app for marketplaces, its just the tool wich i was seeking about.
lets return to adsense, as i know advertisers on adsense dosent care if i have vb, ipb or zero cms, i think the most important is the trafic and the domain name, so i will loose some trafic but i hope i will get it again.
i have trafic decreasing because of that conversion, i will wait some times to see if that will be better
i want to add one of your adsense slot wich i'd installed it on vb, the welcome message ! my adsense revenu are decreasing also
Can I see your work? :)
