<Meta> The most important keywords and descriptions for search engines are as follows:
<Head>
<Title> title </title>
<Meta name = "keywords" content = "webpage description">
<Meta name = "description" content = "keyword">
......
</Head>
Note that currently only the altavista and infoseek search engines support <meta> The <meta> built by some web designers is perfect, however, I found that my website was not behind <meta> at all. That is to say, even if the search engine considers the role of <meta>, it is not the most important factor compared with other factors, many web designers believe that <meta> is a secret weapon that pushes their websites to rank first.
<Meta> should be used on all webpages. At least the ranking score of search engines supporting the <meta> function can be added, it also tells the search engine how to display your webpage description in the result list.
In the key words Field, the keyword frequency rule applies to <meta>. To make the text as concise as possible, you can increase the ranking score.
Description provides an effective way to control the description of your web page, which can replace the web page overview automatically generated by search engines.
<Meta> Note:
Do not repeat the same keyword more than 6 times. We recommend that you repeat it three times for security reasons. Otherwise, the search engine will ignore your webpage or get a penalty.
Do not list duplicate connected keywords. It is easy to see that you are in spam. For example, if you have three keywords, they should not be arranged as follows:
Search, engine, position
And should be arranged as follows:
Search, engine, position, search, engine, position, search, engine, position
Limit the number of <meta> Characters. The number of key words must not exceed 200 characters (including space characters) and description) it should not exceed 150 characters (including space characters). This is to display the maximum length of all text in all search engines that support <meta>; otherwise, extra characters will be dropped.
There should be no carriage return in the html code of the <meta> element.
It is also worth mentioning that robots allows you to describe that a page of your website is not indexed, in the following format:
<Meta name = "robots" content = "noindex">
However, all search engines support this tag. they also support a more powerful function and call the robots.txt text file to achieve the above functions.
