META Tags are used to describe the attributes of an HTML webpage document, such as the author, date and time, webpage description, keywords, and page refresh.
In online marketing methods such as search engine registration and search engine optimization ranking, we usually talk about the role of META tags. We can even say that, the content design of META tags is a crucial factor for search engine marketing, especially the "description" and "Keywords" Keywords) these two attributes are even more important. For more information, see description Keywords ]. Although the current search engine determines the ranking of search results seldom depends on the content in the META tag, the content design of the META tag is still very important.
From the HTML code example, we can see that there are three places in the code that contain meta, and meta does not exist independently, but needs to be connected to other attributes later, such as description, Keywords, and http-equiv. The following describes the composition and functions of META tags that are common in search engine marketing.
META Tags can be divided into two major parts: HTTP-EQUIV and NAME variables.
1. About HTTP-EQUIV in META tag
One of the HTML code examples is:
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312">
It is used to specify the characters used in the current document as gb2312, that is, simplified Chinese characters. Based on this line of code, the browser can identify that the webpage should be displayed with simplified Chinese characters. Similarly, if we replace "gb2312" with "big5", it is a well-known traditional Chinese character.
The HTTP-EQUIV is used to provide some instructions to the browser so that they can be made accordingly. HTTP-EQUIV is not only a description of the character encoding of the web page, the commonly used HTTP-EQUIV type also includes: webpage expiration time, default script language, default style page language, and automatic page refresh time.
2. About "description" in the META tag"
The code in "description" in an HTML code instance is:
<Meta name = "description" content = "network marketing teaching website provides" network marketing basics and Practices "teaching support: network marketing courseware, network marketing papers, network marketing lab teaching, e-commerce papers, online marketing and e-commerce books ">
Content = "webpage description" in "description" is an overview of a webpage, which may appear in the search results. Therefore, you need to design it based on the actual situation of the webpage, avoid "descriptions" that are irrelevant to the webpage content whenever possible. In addition, it is best to have a corresponding description for each webpage (at least the webpage of the same topic has a corresponding description ), instead of using the same description content for the entire website, because a website has multiple webpages, the content of each webpage must be different. If the same description is used, obviously, some webpage content is not directly related. This will not only make the search engine rank the webpage, but also help the user determine whether to click to enter the website to obtain further information based on the information in the search results.
3. About "Keywords" in the META tag"
Similar to "description" in the META tag, "Keywords" is used to describe the attributes of a webpage, except that the content to be listed is "Keywords" rather than the introduction of webpages. This means that you need to select appropriate keywords Based on the subject and content of the webpage. When selecting keywords, in addition to being related to the core content of the web page, it should also be easy for users to search through search engines. keywords that are more unfamiliar with words are not suitable for META tags. For the design of keywords in META Tags, do not pile up too many keywords. listing a large number of keywords does not make much sense for search engine search, for some popular fields (that is, a large number of similar websites), it may even play a side effect.
