As I've said before forums are untested, however I don't see why a forum would be any different from a DDL site, when it comes to earnings. The traffic type is basically the same.

Only thing is, I think you have to be a little agressive with the linking on forums.

  1. Make sure to put a customized link to Sharingzone on at least the first post of each thread, even if it's at the bottom of the page below the download links (of course, near the top is better).
  2. Create a custom search box on your main page at the top, not the default search box that comes with Vbulletin, but a custom one that goes to a custom search results page. On this search results page, your search terms link to Sharingzone using the custom link code.
  3. Based on each search term in #2 above, create a Search Cloud and put it at the bottom of the main forum page, each search term links to Sharingzone using custom search code too.

I believe those steps would get any forum converting almost as well as DDL sites.

I am looking at creating some coding for forum owners at the moment. If you implement the above or code it, let me know.
