How to create a Sitemap xml file

Answer 1

Sitemap or site maps can help SEO positioning, because all pages can be found. In addition, the sitemap consists of an XML file that presents the fields that can be read by a search engine and that in turn allow you to know the structure of the site you are visiting. Sitemap.xml files are used by search engines to better understand the structure of the site. On the other hand the search engines do not have the obligation to follow the links that each page has.

The code that will come within the sitemap.xml file can be;

 <? xml version = "1.0" encoding = "UTF-8"?> <urlset xmlns = "http://www.google.com/schemas/sitemap/0.84" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi: schemaLocation = "http://www.google.com/schemas/sitemap/0.84 http://www.google.com/schemas/sitemap/0.84/sitemap.xsd "> <url> <loc> http://www.nombredelsito.com/ </ loc> <priority> 1 </ priority> </ url> <url> <loc> http://www.nombredelsito.com/index.php </ loc> <lastmod> 2009-05-23 </ lastmod> <priority> 1 </ priority> </ url> <url> <loc> http://www.nombredelsito.com/posts/alojamientoweb.php </ loc> <lastmod> 2009-03-20 </ lastmod> <priority> 0.1 </ priority> </ url> </ urlset> 

The word priority is a way of telling the search engine's robot which pages are preferred to be indexed in the first place:
The priority is that the search engines do not have the need to index the entire site, that is, if it is going to index only one part, first that it indexes the page that is presented with the highest priority and leaves the lowest priority for another analysis.

In http://www.xml-sitemaps.com/ you can access a very useful tool to create sitemaps.
On the other hand, the maximum size that the Sitemap should have is 10Mb.

In a sitemap.txt file, only the URLs of the pages of the site you wish to index will be listed:

http: //sitio/pagina1.html
http: //sitio/pagina2.html
http: //sitio/directorio/pagina3.html

It will be placed at the root of the site and sent to the search engines. Also in the text file only the URLs should appear.

For a sitemap.xml file
It allows additional functions such as including images to be indexed and appear in the results of searches of Google Images, videos, the date of modification of the pages to ensure their reindexacion.

The file is located at the root of the site, it is also possible to include it in the robot.txt.
