News Feeds for content ?

When serps visit sites do they go through the page conent or html content, thus if you have live feeds that are dynamic java coded that show content on your site but not in the coding is this beneficial for adding content and ultimately seo?

thanks

 

It's better if those feeds are indexable pages, rather then just JS, where the SE's can read.

 

True to some extent.. Feeds actually help to keep the content of the pages fresh. It should be for the best interest of visitor and not to fool the bots.
