Does XML feeds, Blogs, Forums help with SEO?

[tatekuhn]

Hey,Would you say having a good XML feed, blog or forum on your site that is relevant to the content on your site help allot with SEO or is it just a good way to drive traffic and keep users coming back? I know SEO fairly well I think but have not used allot of XML feeds, forums, blogs or anything of that sort on my sites. How well is the new google site map working for you guys? Does that help a huge shopping cart etc. get indexed quickly? How many of you write articles and submit them to other sites and how well does that do for driving traffic to a site? Is anyone here willing to give me a run down on their SEO procedure?Thanx and sorry for the mix of questions,JacobSimple awnser, any content which google can read will help.My rss feeds have done wonders for me. They give visitors lots of good things to read. They raise your Alexa rank because you get more visitors. You can add adsense and make money with it. It's great stuff. And it's not duplicate content. All of my pages get good indexing too.
