Positioning in search engines sites has a huge importance in a highly competitive environment. Of this positioning depends many times the success or failure of the site.
A basic requirement so that all that effort achieves optimal results is to make sure that all site pages are properly indexed in the search engines. This will happen when the crawlers of the important search engines visit and indexing those pages with the proper frequency and without omitting any.
A good strategy is to supply to the search engines a "list" of pages that we are interested in being indexed, and with some other information that makes the visit more effective. Specifically, this is done through the use of Sitemaps.
Google XML Sitemap manages the sitemap creation to help major search engines to index our sites.
The Google XML Sitemap is a plugin that can be found in the WordPress repository and which does not need close attention on our part. Only we have to do a first setting, focusing on aspects that we create interesting for the sitemap creation on our site (http://markosweb.org).
