Creating Google Sitemaps for Magento sites
This is an old revision of the document!
Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. In its simplest form, a Sitemap is a plain text file that lists URLs for a website. A Sitemap can also be provided in an XML format that includes additional metadata about each URL so that search engines can more intelligently crawl the site.
All major search engines use the same format for their sitemaps. Magento refers to them as “Google Sitemaps” but they are actually supported by Yahoo! and Microsoft search engines as well. This common sitemap format is documented at http://www.sitemaps.org/.
Magento can create Google sitemaps automatically. Sitemaps are defined in Admin > Catalog > Google Sitemap. Magento sitemaps contain the URLs for Category pages, Product pages and CMS pages.
Once you’ve defined your sitemaps, you can manually generate each sitemap by replacing the “1” at the end of the below link with the actual sitemap id:
Magento can be set up to automatically refresh Google Sitemaps at regular intervals. This function is configured in Admin > System > Configuration > Google Sitemap.
To use Magento’s automatic generation of Google Sitemaps, you must activate the Magento Cron service.
