Therefore to achieve this we need a map of our site, or as they say in English, we need a sitemap. That is a sitemap? A sitemap is an XML file that contains a list of the pages on the site along with some additional information, such as how often the page changes its contents, when was your last update and how important it is compared to the rest of the pages on the same site. Sitemaps are especially useful if:-your site has pages that do not are easily discovered by Googlebot during the crawl process for example, pages with rich AJAX or Flash. -Your site is new and has few links with him. (Googlebot crawls the Web by following links from one page to another, so if your site is not properly connected, it can be difficult for us to discover.) -Your site has a large archive of content pages that are not well connected among themselves, or are not linked at all. The XML file well built is hosted on the server as one file of the site, with the exception that may contain the URLs contained in the same directory in which it is located or other content in. If your web site is built on WordPress I recommend that you use the Sitemap Generator Plugin which creates the sitemap for you, alerts you to the principal that your site search engines to been updated, ponders all the necessary fields and also updates automatically whenever your update your site.
If your site is built on another platform, one of the best services is XML Sitemaps this website, creates your sitemap when you indicate the URL of your site, after created, you can download it and upload it to your server through an FTP program. The only drawback of this method is that you must create yourself your sitemap every time that upgrade your site, either once a week or a month.
