As a base document for the website, site maps serve as a guide for google to quickly and accurately understand and access the site, so it is recommended that you be able to configure your website in a timely manner. Although, theoretically, the current google has been able to identify and capture the site on its own initiative, it is not enough for a marketing site to rely solely on google's initiative, so the article will discuss the topic of site maps in a relatively systematic way, which you may wish to learn from。
Discussion of the need for site maps relying on google's official version. The following types of site maps have to be configured:
One, the size of the website: when your website becomes very large, it means that it will contain hundreds or even thousands of pages, and although there will be hyperlinks between pages, google will be more difficult to discover with links. It is also important to take into account googlebot's patience on the website, and if google spiders are always around your site to find new content, then it is likely to affect the frequency of their subsequent capture of your site。
2. Insufficient internal/external links to the website: the lack of internal links means that the site contains a large number of professional pages or content archive pages that are not sufficiently linked to other pages, which means google is hard to find. Fewer than half of the external links refer to new sites, and there are few or no other sites on the internet, which will also make it difficult for google to find your site or access it in its entirety。
3. The issue of web content: many web sites, because of their visual impact or the special nature of their industry, have a large amount of content in the media, which cannot be found in google without a map of the site. The creation of site maps, currently supported by the mainstream search engine, consists mainly of site map formats in the form of xml, pss, text (txt) and other forms, such as atom1. 0 and so on, although the recommendations are still in the most common form of xml or txt, with the principle that site maps are highly generic and user-friendly, without the need for new indications. 1. The xml format is the most recommended site map, with almost all search engines being universal and efficient in use and maintenance, and the highest degree of compatibility of the site-building procedures。

This is a particularly typical and standard form of xml site maps, which are now generally not handled by seo personnel, and are generally supported by site-building programmes that are generated and updated in real time and are configured accordingly。
The text (txt) can be used in the form of a secondary site map, with little to say, a few places. It must be uft-8-coded, otherwise unidentifiable。
1, googleconsole, help centre, which can be submitted directly
2. A ping tool can be used to send a get request directly to the browser input order in the following format: https://www. Google. Com/ping? Sitemap=full url uf sitemap, which is used when replacing the address behind the site map。
3 the location of the site map can be indicated in the robots file by using the robots file and can be captured by google. Site: https://example. Com/my sitemap. Xml, replace ";" with a link to your site map. Iv. Disaggregation of site maps (applies to site map documents that are too large because they are too large) is recommended if the site map exceeds 50 mb because it is too large, regardless of google or the country's 100 degrees, with little support for the site map. Google, however, has different views on this issue and, for google, it is more recommended that multiple site maps be submitted in the form of site map indexing files. A simple understanding is to create a “site map” for multiple site maps, allowing google to retrieve different site maps through site map indexing, thus capturing specific web links。

As above, it is a standard site map index format, with specific reference to the above. Explain what the labels mean:
Setimapindex: a label that can be understood as the beginning and end of the site map index; sitimap: a specific link to a different site map; loc: a specific link to a site map; as an index to a site map, the same size cannot exceed 50 mb and the number of sites contained in it cannot exceed 50,000, although this generally does not worry that the average enterprise site site map index will not exceed that number。
V. With regard to the extension of site maps and their attention, it is not necessary to say individually that some things are different or misleading, but the principle of site maps is universal and easy to use, so be honest with the relevant rules and make sure that they are correct。
1. It is proposed to use absolute instead of relative paths, which is different from 100 degrees
2 a site map supports only one form of a normative web site, such as your web site, which can be accessed both with and without www, so that the site map can contain only one of these sites and not either, even if it opens the same content as the post page
3. Site maps are intended to tell google how to capture your website more efficiently, but this does not mean that google will have to capture and record your site on site maps
4. In principle, the location and sequencing of a particular site on the site map is not important and google will not treat a particular site differently from that
All right, that's basically enough for site maps to be combed down, and for the vast majority of enterprise websites, it is enough to follow the above line to ensure that it is not wrong. Some of the special types of site maps are operating differently from above, such as pure photo stations, news stations, etc., although this is a relatively small area and is not mentioned。
