Why, then? The reason is very simple, these two statements can let the search engine can accurately discover you, attracts more people to visit
Your site!

According to the current popular search engine (Lycos,altavista, etc.) working principle, search engine first dispatched robot automatic
Search on www And when new sites are found, they retrieve keywords and decription from the page and add them to the
Your database, and then sort the sites according to the density of the keywords.

Other words:
1. If you don't have keywords and description meta tags on your page, then the robot is
Can not add your site to the database, users will not be able to search your site.

2. If your keyword selection is not good, the keyword density is not high, is ranked in dozens of or even millions of of the back of the site
The likelihood of being clicked is also very small.

So we have to remember to add the META tags for keywords and description, and write the keywords and introductions as best we can.

The taboo for writing keywords is:
1. Do not use common vocabulary. such as Www,homepage,net,web and so on.
2. Do not use adjectives, adverbs. such as the best, the biggest and so on.
3. Do not use a general vocabulary, to be as accurate as possible. For example, instead of "Motorola phone", switch to "V998" and so on

One technique for finding the right keywords is: Go to Lycos,alta,infoseek and other search engines, and search is similar to your content
Website to view the meta keywords of the top ten sites, copy down and use them on your site.

Here, we give a section of Microsoft Multimedia website keywords for your reference:
<meta name= "keywords" content= "joke, music, MP3, media, audio,
Joke of the day, downloads, free music, horoscope, radio, video,
