These are some of the basic uses of META tags, the most important of which are: keywords and description settings. Why, then? The reason is very simple, these two statements can make the search engine can accurately find you, attract more people to visit your site! According to the current popular search engine (Google,lycos,altavista, etc.) working principle, search engine first send robot automatically on WWW search, when discovering new website, Easy to retrieve the keywords and description in the page and add it to your database, then sort the site according to the density of the keyword.
From that point of view, we must remember to add keywords and description meta tags and write the keywords and introductions as much as possible. Otherwise, the consequences would be:
If your page does not have keywords and description meta tags, then the robot is unable to add your site to the database, users will not be able to search your site.
If your keyword selection is not good, the keyword density is not high, is ranked in the dozens of or even millions of of sites are clicked on the possibility is very small.
Write good Keywords (keywords) to note the following points:
Don't use common words. such as WWW, homepage, net, web and so on.
Do not use adjectives, adverbs. such as the best, the biggest and so on.
Don't use a general vocabulary, try to be as precise as possible. For example, "Ericsson mobile Phones", the switch to "T28SC" will be better.
"The three men's trip, must have my teacher", looking for the right keyword skill is: to Google, Lycos, Alta and other famous search engines, search and your site content similar to the site, to see the top ten of the site's meta keyword, they used on your website, the effect can be imagined.
★ Small Tips
