Google site map is a way of informing google of all the pages you have added on your websites. Through Google site maps you can tell google as to which pages are more important to you and which pages have been updated.

 

Site map generators have been popping up on the web. Some sitemap generators are easy to use while some are very complex. You need to create three separate sitemaps for your website

 

Site map in html

Site map in xml

Site map in txt

I don't have any for any of my sites. I did for a couple and found they really did no good. I do have a static page with l;inks to important articles that works very well.
