Search engines such as Google discover information about your site by employing software known as "spiders" to crawl the web. Once the spiders find a site, they follow links within the site to gather information about all the pages. The spiders periodically revisit sites to find new or changed content. For MyMall merchants, the way to enable Google Sitemaps is easy, just login to admin site and you will see the tiny Google icon displayed on the main page, tick the check box, and click "update" button to activate the function. However, it doesn’t mean your website would be rank at top position when you enabled Google Sitemap. There are many factors which affect your site rank, eg. site popularity, keywords indexing, keywords density, meta tags, etc.
