I have an wordpress blog and i already install google sitemap on it, but google sitemap don`t work..did u any ideal for this..
What is google sitemap a sitemap is something you add to google webmaster tools if thats what you mean then what exactly isnt working.
You can check sitemap.xml on your server whether that is getting updated after a new post. If not then create a new blank sitemap.xml and builld sitemap from google sitemap manually. Let us know whether it worked.
You can make a sitemap manual then submit it to google ,and then google will discover your new posts!
