I set up a forum using Invisionfree three years ago, unexpectedly it has snowballed and it now has 6500 members (albeit many will be one time or occasional rather than regulars), and I also have two informal advertisers with banners in the forum index in return for a discount on a couple of products. It also generates a small amount of cash via donations. Presently the only cost to me is opting out of the advertising arranged by Invisionfree.
The forum comes up on the first page of Google when someone searches for the manufacturer, and occupies the first three results if someone searches for specifically for a forum, so there are always a high level of guests browsing as well.
Are there any forum hosts out there (I would expect to have to pay) that will allow me to ‘port’ over the content and members with minimal disruption, and then allow me to earn the income from google ads? Is there anywhere that will tell me what to expect in terms of income from this number of users?
