<name= "keywords" content= "xx_xx_xxx"/>
Baidu search on a bit, saw a detailed introduction as follows:
The META tag is an accessible tag in the head area of the HTML language, which is located between the <HEAD> tag and the <TITLE> tag in the header of the HTML document, which provides information that is not visible to the user. Meta tags are often used to define page themes for search engine robots, or to define a cookie on a user's browser, which can be used to identify the author, format the page, annotate the content feed and keywords, and set the page to refresh itself according to the intervals you define. and set the RASC content level, and so on.
Name is a description of the Web page, corresponding to the content (Web page contents), so that search engine robots to find, classify (currently almost all search engines use online robots automatically find meta values to classify Web pages).
The value of name (name= "") specifies the type of information provided. Some of the values are already defined. such as description (description), keyword (keyword), refresh, and so on. You can also specify any other value, such as: CreationDate (Date Created),
Document ID (DOC number) and level (rank), and so on.
The content of name specifies the actual contents. For example, if the level (rank) is value (value), content may be beginner (beginner), intermediate (intermediate), advanced.
1, Keywords (keywords)
Description: A list of keywords for search engines
Usage: <meta name= "Keywords" content= "keyword 1, keyword 2, keyword 3, keyword 4,......" >
Note: Each keyword is separated by a comma ",". The usual use of meta is to specify keywords that search engines use to improve search quality. When several meta elements provide document language dependency information, search engines use the Lang feature to filter and display search results through the user's language precedence reference. For example:
<meta name= "Kyewords" lang= "EN" content= "Vacation,greece,sunshine" >
<meta name= "Kyewords" lang= "FR" content= "Vacances,grè:ce,soleil" >
