Forums can be an incredibly rich resource. Even a moderately active forum could have hundreds of posts and provide plenty of keyword rich content. Unfortunately due to their very nature it can be quite hard to get the most out of a forum.
If you are using
Vbulletin to run your forum(s) there are a number of options open to you.
If you have a look on the
Vbulletin hacks and mods site you can come across a number of modifications that combine mod_rewrite and a few other tricks to make your site that little bit more search engine friendly. However there are always ways that you could improve on this, but do you really have the time and the skill to do it?
VBSeo is by far the best solution that I've found for this.
Not only does it convert all the ugly URLs into more keyword rich static links, but it also offers a wide range of custom options to help remove duplicate links and give search engine spiders rich and unique content to spider.
It may seem like a hefty investment, but it can definitely pay dividends both in terms of traffic and earnings, be they from Adsense or other sources.
