Last year, and some of this year, I've been doing quite a bit of online advertising to attract new members to the fourm. Some have worked well, others not so much. Apart from PPC and AdWords, I was wondering where else have forum owners advertised that have bought a good amount of new members (not just traffic). I'm talking paid sources, not including search engines or directories or even swapping links. My forum is a humour/'waste time' kind of site so I've been placing text links on humor sites and bought the odd newsletter space. http://www.adengage.com - has been a good place, especially advertising in www.i-am-bored.com and www.youthink.com. Another advertising broker is http://www.adbrite.com, this has a few good sites that I found. Both these places have a wide range of websites for all owners to advertise on, not just humour related. I also tried a few ads on blogs from here - http://www.blogads.com - I found blogs weren't as effective in getting new users though. Has anyone got any ideas on other places to advertise?
