About <meta NAME = "keywords" CONTENT = "">, metakeywords
I finally joined a small startup company as an intern yesterday. Today I am asked to read more about other people's web pages and find something I have never followed before.
<meta name="keywords" content="XX_XX_XXX"/>
I searched Baidu and saw a detailed introduction as follows:
The META tag is an auxiliary tag in the HEAD area of the HTML language. It is located between the <HEAD> tag and the <TITLE> tag in the header of the HTML document. It provides invisible information to users. Meta Tags are usually used to define a page topic for the search engine robots or a cookie on the user's browser. They can be used to identify the author, set the page format, and label the content feed and keywords; you can also set a page to refresh yourself according to the defined time interval, and set the RASC content level.
Name indicates the webpage, corresponding to Content (webpage Content ), this allows search engines to search for and classify robots. (currently, almost all search engines use online robots to automatically search for meta values to classify webpages ).
The value (name = "") of name specifies the type of information provided. Some values are defined. Such as description, keyword, and refresh. Other values, such as creationdate ),
Document ID (document number) and level (level.
The content of name specifies the actual content. For example, if the specified level (level) is value, the Content may be beginner (Elementary), intermediate (intermediate), and advanced (advanced ).
1. Keywords)
Keywords list provided for search engines
Usage: <Meta name = "Keywords" Content = "keyword 1, keyword 2, keyword 3, keyword 4 ,...... ">
Note: keywords are separated by commas. META is usually used to specify keywords used by search engines to improve the search quality. When several META elements provide document language subordination information, the search engine uses the lang feature to filter and display the search results through users' language preference. For example:
<Meta name = "Kyewords" Lang = "EN" Content = "vacation, greece, sunshine">
<Meta name = "Kyewords" Lang = "FR" Content = "vacances, gr è: ce, soleil">
2. Description)
Description: Description is used to tell the search engine the main content of your website.
Usage: <Meta name = "Description" Content = "Brief introduction to your webpage">

3. Robots (robot wizard)

Note: Many search engines log on to the website by releasing a robot/spider search. These robot/spider will use some features of the meta element to determine how to log on.
All: files will be retrieved, and links on the page can be queried;
None: the file will not be retrieved, and the link on the page cannot be queried; (same as "noindex, no follow)
Index: the file will be retrieved. (log on to robot/spider)
