Technically, it’s not just about pretty links and sitemaps. BBPress can produce much cleaner, better structured page code than certain other forum software.

Meta descriptions and keywords are still used by search engines where available. Personally I take the tags associated with each topic and add them to the list of keywords. In the keywords meta:

global $tags;

if($tags) {

foreach ($tags as $t) {

echo $t->raw_tag.', ';

}

}

That said, I still believe that asking whether something is SEO-friendly is asking the wrong question. Work on making forums user-friendly, which then attracts “quality” posts, and the search engines will follow.
