I usually use a sitemap generator online xml-sitemap generator something but it is limited to 500 pages. Is there other websites to make bigger xml sitemaps? Thanks for any advise
Yeah http://www.auditmypc.com/free-sitemap-generator.asp Code (markup): It's written in Java. A bit complicated at first, but they provide a tutorial.
Alot depends on the cms you are using... Even if its 100% inhouse you can easily write one that runs from your database
query the database output the xml headers output the text string for the contents of the database Basically open an existing sitemap, get comfortable with the structure and code it to replicate that.
