Sitemap for forum is good?

Hi Guys,

I have created a forum now I was thinking to create sitemap and submit to Google so that Google come to know about my pages but I have heard it is not good to create sitemap for forum as they have dynamic contents.

Is it really no worth? If no then how Google will index the pages?

 

You should create a sitemap for your forum, it doesn`t matter it`s dynamic, Google will crawl your site regularly and update for you.

 

Sitemaps are particularly helpful if:

• Your site has dynamic content.
• Your site has pages that aren't easily discovered by Googlebot during the crawl process—for example, pages featuring rich AJAX or images.
• Your site is new and has few links to it. (Googlebot crawls the web by following links from one page to another, so if your site isn't well linked, it may be hard for us to discover it.)
• Your site has a large archive of content pages that are not well linked to each other, or are not linked at all.

Ok. That would be great. I was wondering if Google can index topics at my forum too.
