Forum Moderators: not2easy
Mindful of the need (both for SEs and human visitors) to keep adding content, I also added a blog-based content manager (to allow the site principals to keep adding new articles) and a discussion forum.
The site has prospered from a traffic standpoint, particularly with Google's deep linking. Rightly so, IMHO, since the content is better and deeper than most other sites in its category. With growing traffic, the discussion forum has hit critical mass and is now adding dozens of new pages to the site daily.
The discussion is all on-topic, but I'm concerned that what was originally a small fraction of the total site content is becoming the the largest area. As discussion continues to accelerate, the addition of discussion pages will greatly outstrip the addition of other content.
Should I worry about this? My site navigation still favors the major topics with articles and the like, and these have high PR. Google seems to be doing a good job of keeping things straight so far, but I'm concerned about reaching the point when my non-discussion content is less than 10% of the total. Comments?
Or, find a way to set the site up so that discussions are closed down after a certain period of time. Maybe each new article has a related discussion which is only open for 10 days after publication, or 30 days, or whatever. That would limit the discussion relative to the volume of non-discussion content, but if you keep adding new content frequently enough it would hopefully keep your loyal visitors coming back with frequent new topics to discuss.
<added>If you're primarily concerned about the SEs possibly thinking the discussions are 'watering down' your site's relevance to your target search phrases, you could always just set up the discussion pages to not be indexable...</added>
I'm sure this will change, it might be worth looking at how Teoma works for an insight into something a bit more context sensitive.
