Google returns which requests to search engines will lead to your pages and the pages that have not been indexed.

Simple Map, the screen

XML, text or HTML, which format to choose?

The XML format is now recognized by main search engines. It is intended to give various information to Googlebot and other crawlers. This XML document is generated by Simple Map according to the standard specification.
- The priority tag indicates which pages are the most important ones.
- The lastmod tag, gives the date of the last modification. Used along with the frequency attribute.
- The changefreq tag, is the frequency of scanning by the robot, from always, for a very big website with pages changing continuously, to yearly or never, for static pages. As for W3C specifications of formats with a version number.

The text format gives only the list of URL of pages to be indexed. It is accepted by Google.

The HTML format is for visitors of your website. It may display links, titles, descriptions or other infos. It is scanned by search engines and allows to give URL of pages that are not indexed, specially in the case of multi-level sub-directories, since deeper levels are not always scanned

The plain text or HTML files are simple list of URLs, but the XML format is made of tags corresponding to a standard format.

Sitemap index

A sitemap index is a file holding a list of sitemaps. It allows if you have several maps or if the file is splitted into several file, to give the URLs.
You do not need to create an index if you have only one sitemap file and even if you have multiple sitemaps for different contents, they may be joined in a single file, as explained further.

The index file has a standard XML format too.
The container is sitemapindex and it holds a set of inner sitemap tags.

<sitemapindex xmlns="">

Multiple contents in one sitemap

To cope with the proliferation of types of sitemap files, Google has decided to integrate all types of content in a single file.
The multiple file contents looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns=""
<video:title>Look growing the youngest.</video:title>

Thus three types of tags in the URL tag: loc for a page, image plus image:loc to an image file, and video with video:content_loc.

Once the sitemap is registered, when it is updated you don't have to register it again, you can inform the search engine that the file is modified by a ping:

Replace by the URL of your website, and by the URL provided by the search engine: yahoo, ask, etc.

3) Use the robots.txt file

According to the blog of Google, you can now add a sitemap entry to the robots.txt file, and the sitemap is parsed when the robot of Google and other search engines encounters this file. the syntax is:

User-Agent: *
