Google Sitemap is used to make your site visible in Google Search Engine. This section supports multi-language and can be accessed from Extensions > Product Feeds > Google Sitemap in the administration.
How it works?
This section enables you connect to two product feed tools, Google Base and Google Sitemap. You need to create an account at the Google Merchant Center to access these tools. Google Base requires the user to upload product information in product feeds so that they can show up in Google's search engine. Google Sitemap uses a data url from the store website to provide information to its search engine to crawl the store's website. In the edit section of Product Feeds, you must link to the store's data feed URL obtained from the Google Merchant Center.
