Zen Cart, at the moment does not support the inclusion of EZ pages on the site map page. If you want your EZ pages to show on your zen cart site map, I would recommend installing the EZ Pages on Sitemap Zen Cart Module. It will allow you to add Ez-pages which are defined and activated in the sidebox to show on the site map.
What is a Sitemap?
Sitemaps, as the name implies, are just a map of your zen cart site – i.e. on one single page you show the structure of your site, its sections, the links between them, etc. Sitemaps make navigating your site easier and having an updated sitemap on your site is good both for your users and for search engines. Sitemaps are an important way of communication with search engines. While in robots.txt you tell search engines which parts of your site to exclude from indexing, in your site map you tell search engines where you’d like them to go.
Why Are Sitemaps Important in Zen Cart?
Sitemaps come with many benefits, not the least of which is easier navigation. They also help improve your site’s google ranking by informing search engines immediately about any changes on your site. Another benefit is that when you have a sitemap and submit it to the search engines, you don’t have to rely as much on external links to bring search engines to your site.
Also, if your site is new, or if you have a large ammount of new or recently updated pages, then using a sitemap can be vital to your success. While you can still get through without a sitemap, it is likely that sitemaps will soon become the standard submission method of data to search engines. Spiders will certainly continue to index the Web and sitemaps will not make the standard crawling procedures obsolete, but it is very likely importance of sitemaps will continue to increase.
