The above are some basic usages of META tags, the most important of which are: Keywords and Description settings. why? The reason is very simple. These two statements can allow search engines to accurately discover you and attract more people to visit your site! According to the working principle of popular search engines (Google, Lycos, AltaVista, etc.), search engines first send robots Automatically search on the WWW. When a new website is discovered, it is easy to retrieve the Keywords and Description in the page, add it to its own database, and then sort the websites according to the density of the keywords.
From this point of view, we must remember to add the META tags of Keywords and Description, and write as good a keyword and introduction as possible. otherwise,
The consequences will be:
●If there are no META tags of Keywords and Description in your page, then robots will not be able to add your site to the database, and it will be impossible for netizens to search for your site.
●If your keywords are not well chosen and the keyword density is not high, the possibility of being ranked behind dozens or even millions of sites and being clicked is also very small.
When writing Keywords (keywords), you should pay attention to the following points:
●Don’t use common words. For example www, homepage, net, web, etc.
● Don’t use adjectives or adverbs. For example best, biggest etc.
●Don’t use general terms, be as precise as possible. For example, for "Ericsson Mobile Phone", it would be better to use "T28SC" instead.
"On a trip of three, there must be a teacher." The trick to find suitable keywords is: go to famous search engines such as Google, Lycos, Alta, etc., and search with
For websites with similar content to yours, check the META keywords of the top ten websites and use them on your website. The effect can be imagined.

●In order to increase the density of keywords, hide the keywords in the page (define the text color to be the same as the background color). (* Not recommended)
● Add keywords to the ALT comment statement of the image. For example:
