Create a sitemap
You should use a sitemap to make sure your website is indexed correctly.
Use the Sitemap Generator to organize your website and to make sure that search engines find all pages. This is particularly important when the site was created using Macromedia Flash or Java-Script menus that don’t contain HTML links.
If your website has more than 10.000 single pages, you might need to create multiple sitemaps.
Don’t forget to add your sitemap to the robots.txt Robots.txt after you created it.
