If someone would kindly take a look at my soccer forum at thefantasyfootballforum.com/forum and confirm whether I can add any more adsense ads? Please ignore the homepage, there will be lots of content on it before its finished over the weekend. So, regards to the forum------- I have a block of 3 and sometimes this changes to 4 ads just below the banner so I presume this represents 1 ad unit? I have a block of 5 ads down the right hand side so I presume this also represents another 1 ad unit? The big question is Can I add one more unit and would this be limited to 4 or 5 adverts? Thanks
You have 1 leaderboard unit (the big horizontal one up top with 3/4 individual links) and 1 skyscraper unit (the vertical one on the right with 5 individual links). You're allowed 3 ad units in total, so you could add another one somewhere. An easier way of thinking about it - you have pasted the code of 2 ad units, so can paste the code once more. Don't think about the individual links within the units.
For me... especially forums, I would stay a unit below the maximum because having so many ads may drive members away from your site.
You might consider replacing the skyscraper with a large rectangle placed closer to the content. I don't think it's going to get eyeballed very much where it is... Just my experience. The forum looks like a cool idea, though. Good luck! P.S. Don't forget about referrals. You could put a text referral link for Adsense next to a bullet point below the first post, if possible. I just made $250 for one conversion on my blog (apples to oranges, but maybe it will work...)
