The important communication way of Sitemap and search engine

Google SiteMap Kyoto is Google's own launch of a site map protocol, which is based on the early robots.txt file protocol, and has been upgraded. In Google's official guide, it is noted that a site that joins Google Sitemap will be more useful for crawling indexing of Google web crawler robots, which will improve the efficiency and accuracy of indexing site content. The file protocol applies a simple XML format, with a total of 6 tags, with key tags including link addresses, update times, update frequencies, and index precedence.

The Google sitemap file is generated in the following format:
<urlset xmlns= "http://www.google.com/schemas/sitemap/0.84" >
<url>
<loc>http://www.ithov.com</loc>
<lastmod>2008-12-03T04:20-08:00</lastmod>

There are a lot of SEO tips and tricks to help in optimizing a site, but one of its importance is sometimes underestimated by the site map. Because as the name suggests, just a map of the site-that is, on a single page showing the structure of your site, its parts, the links between them, etc. sitemaps makes your site easy to browse and has a website to update your site is good for your users and search engines. Sitemaps is an important way to communicate with search engines. While your robots.txt tells the search engine which parts of your site to exclude the index, in your sitemap You tell the search engines you want them to go.

Sitemaps is not a new thing. They have always been the best web design practice, but through the site's search engines, now they become more important. However, it is necessary to clarify if you are interested in Sitemap, mainly SEO perspective, you can not go with the traditional site only (although currently Yahoo and MSN still keep the standard HTML format) For example, Google's Sitemaps uses a special (XML) The format is different from the general HTML site map for users to browse.

One might ask why two sitemaps is necessary. The answer is obvious. One is for the user, the other is directed at the spider (Currently the main Googlebot will, but it is reasonable to expect that other search engines to join this agreement soon). In this connection it is necessary to clarify that two sitemaps are not considered duplicates. In Webmaster Tools, Google makes it clear that using Sitemap will not result in penalties for your site.

Why use Sitemap

Using sitemaps has many advantages, not only easy navigation and visibility of better search engines. Site maps provide an opportunity to inform the immediate search engine of any changes to your site. Of course, you can't expect search engines to be anxious to immediately index your updated pages, but certainly the changes will be quicker than the index when you don't have a website.

Also, when you have a website and submit it to a search engine, you are less reliant on external links to make the search engine your site. Websites can even help confuse internal links. For example, if you accidentally break an internal link or become an independent web page, there is no other way to do it (although there is no doubt that it is much better to solve your error than relying on a sitemap).
