SMF Forum stuck in supplementals

[chazeo]

OK, so after noticing that my popular forum built on the SMF platform does not rank for any keywords, I did some searching and site: commands and found that it is all supplemental! Even the main page is supplemental results, and the Pagerank bar is grayed out. I had the forum created as a subdomain of a main site, which is a blog and the main site ranks incredibly well and is totally original content (blog) and a GREAT resource.

What recommendations do you have to pull this incredibly relevant and valuable forum from out of the wasteland of supplementals?

There are many factors that can cause forums to have troubles. I'd suggest checking out these two threads about two other forum platforms. They may be different software -- but the basic issues are very likely the same.

Vbulletin [webmasterworld.com]
Wordpress [webmasterworld.com]

I have no specific experience with SEO for a SimpleMachineForum - but perhaps someone else does and can offer some details on to look out for.

I found a post on the SMF boards [simplemachines.org...]

However, there seems to be some debate about whether SMF already has this feature integrated into it as a default.
