Although many requirements in the production of the site is a tree-shaped structure, but due to a variety of restrictions, the site is not a complete tree or network-type structure. Therefore, the need for site map to play the role of auxiliary navigation: for users, can be clear to the content of the site; for search engines, you can track links crawling to the main part of the site: and for the site itself, it will make the site appear more standardized and professional. Therefore, the site map for a site is very necessary.

General site map is divided into two types: HTML version of the site map, the other is the XML version of the site map. The following are described below:

First, the HTML version of the site map: This version of the site map English name is sitemap,s for lowercase, specifically for the HTML version, this version is the user can see through the site and list all the pages linked to the page. For some use JS or pictures too much, or even the whole site Flash website, site Map is particularly important, is a search engine crawling an important supplement. For small sites, HTML version of the site map can train all the pages of the station. For medium-sized sites, it is not possible to list all the pages, you can list the focus of the level one or two classification page, or can be the site map for the block, the first list of a level of directory, down a list of level two directory, so that the cycle down, can also be a large number of pages listed. In fact, a good navigation system and internal link structure of the site, it is not necessarily necessary to list all the pages linked to the site map, because for search engines and users, the nature of the two are similar.

Second, the XML version of the site map: This version of the site map in English name Sitemap, but s is usually uppercase. The XML sitemap was first proposed by Google in 2005, followed by various search engines including Baidu. The XML version of the site map is all composed of XML tags, the file itself must be UTF8 encoded. XML map is a list of most of the sites need to be included in the URL, a general line of a URL, search engines will follow these URLs to crawl. In addition, the XML version of the site map there are some tags we have to master: priority, indicating the importance of the URL, the default is 0.5, the most important for 1.0;changefreg, indicating the frequency of updates, the general need to choose daily, said every day will update the site; The XML sitemap can list up to 50,000 URLs and the file cannot exceed 10MB. If you exceed this size, you can use more than one sitemap.

After the site map is made, it can be submitted directly to the search engine through the tools, most of the search engines support the submission and also have a special submission portal. In addition, you can also use the form of robots.txt file to inform search engine site map location. Note that through the XML site map, just notify search engine those pages need to be included, just let search engine know these pages exist, but do not guarantee will be included, need to be included must also meet the minimum standard, so do not think that there is a site map without regard to the site structure and reasonable internal links.

The last thing to say is that the site map for large sites is particularly important for the general small and medium enterprises and personal sites also have a certain importance, but the embodiment is not obvious. Therefore, we understand the site map, according to their own situation, make a suitable site map of their own.
