Differences between site map Sitemaps in HTML and XML

XML (extensible Markup Language) expands the markup language, which, like HTML, is SGML (Standard generalized Markup Language, Standard Universal Markup Language). XML is a cross-platform, content-dependent technology in an Internet environment and a powerful tool for dealing with structured document information at the moment. Extensible Markup Language XML is a simple data storage language that uses a series of simple tags to describe data that can be built in a convenient way, although XML takes up more space than binary data, but XML is extremely simple and easy to master and use.

Unlike databases such as access,oracle and SQL Server, the database provides more robust data storage and analysis capabilities, such as data indexing, sorting, lookup, correlation consistency, and so on, and XML is just presenting data. In fact, the biggest difference between XML and other data forms is that he is extremely simple. This is an advantage that looks trivial, but it makes XML unique.

HTML (hypertext mark-up Language), the Hypertext Markup Language or hyper-text link marking language, is the most widely used language on the Internet, and it is also the main language that makes up Web documents. The purpose of designing an HTML language is to be able to easily link text or graphics stored in one computer to text or graphics on another computer, to form an organic whole, without having to consider whether the specific information is on the current computer or on other computers on the network. We simply use the mouse to click an icon in a document, and the Internet immediately goes to the content associated with this icon, which may be stored on another computer on the network. HTML text is a descriptive text consisting of HTML commands that can describe text, graphics, animations, sounds, tables, links, and so on. The structure of HTML consists of a head, a body, two parts of the head, which describes the information required by the browser, and the body contains the specific content to be described.

In addition, HTML is the common language of the network, a simple, universal, full markup language. It allows web makers to create complex pages of text and images that can be browsed by any other person on the web, regardless of the type of computer or browser used. It's not magic at all, because now you're looking at a page written in this language!

Mistakenly think that HTML and XML are just the language of the site map, because the XML and HTML languages are actually not very different.

But in fact, an XML site map is the real meaning of SEO domain sitemaps, is to search engines to see, tell search engine which page is important page, equivalent to the search engine a steering wheel, as well as update the frequency, that is to tell the search engine interval how long should visit once; But the XML site map is also for the search engine to provide a reference, the search engine does not necessarily exactly according to the parameters you set to finalize.

Second, the HTML site map is the traditional sense of the site map, is addressed to users of the site to see. It is equivalent to a directory, to the user to understand the network structure of the entire site, not lost.

Iii. the difference between creating an XML and an HTML site map: A lot of websites that create Web sites on the website are Web sites that support the creation of both formats; but most of the time, HTML site maps are generated automatically when the site is made, and do not need to write themselves or have a third party generated; The format of the site map there are many third-party Web sites or institutions can be generated free of charge, such as http://www.xml-sitemaps.com/after the generation can then modify the priority. about how to create a site map and upload Google, my last article has said, if necessary, you can click to understand.
