When i started my forum, i didn't have intentions of earning money. But after about three months, I put up ads that can be seen by guests only. The ads are strategically placed beneath the thread starter and at the footer of the page. I have considered placing more ads on the page, to the maximum allowed but have not ventured into that. So far, I'm not earning a good deal of money with Adsense on the forums as most clicks are coming from my blogs/articles. Just wondering if there is a secret to earning Adsense money on a forum.
