Relationship with navigation platform registration
Because the text defined in the meta tag item is not displayed in the browser, this tag item is generally used to define content that cannot be reflected by other tag items. The items related to the navigation platform registration include the keywords and description of the name item.
1. Operating mechanism of the navigation platform:
The navigation platform uses different background programs, resulting in different operating mechanisms. A type of navigation platform is represented by yahoo, and its background is a large database. Before adding the website to the database, you need to manually review the site for registration, then, enter the information in the database on the management interface for query. There are also a lot of navigation stations that do not rely on manual review of web pages, but how you register, I will give you indexing. This type of navigation platform is generally called navigators or directries. In addition to databases, the background of the second type of navigation platform also has special programs used to automatically access the homepage content of the site for registration, and extract the title and description required by the navigation platform) and keywords. This kind of navigation platform is also called: Robots, Crawlers, wanders, Spiders and so on.
2. Relationship between meta tag items and navigation platform registration:
Obviously, the meta tag on the home page does not work for the first category of navigators, but is only useful for the second category of navigators.
In the second category, some navigators need to index the meta items on the home page, and are automatically indexing programs. This provides a powerful webmaster. This is also the relationship between the meta tag items and the navigation bar ranking.
Just like fishing, to catch fish, you must give different bait based on your preferences. After carefully studying the characteristics and laws of the second type of navigation platform, people will summarize a set of empirical methods. Based on this method, they will be able to get a better ranking in the navigation platform.
Meta definition skills
1. You must define the meta tag and the first 200 characters of the homepage body as text that reflects the homepage topic. Some navigators index the first 200 characters in the text while indexing the keywords in the meta item. For example, altavista. Therefore, when some people check the registration result after registering the navigation bar, they find that the description in the navigation bar is not what you want, but text such as copyright description. The reason for this phenomenon is that you did not notice this.
2. Place the meta tag item of the definition keyword before the meta item of the definition description. For example:
<Foreign Ype = "keywords" content = "......,...">
<Ype = "description" content = "...,...,...">
3. Place the most important keywords at the beginning, so that the relevant keywords are adjacent. All lowercase letters and initials coexist, because some navigators are case sensitive to characters during indexing. Contain up to 250 punctuation characters
4. It is best not to use the frame structure for the homepage, because after the frame divides the screen into multiple windows, the navigator cannot intelligently select the homepage in the correct window for indexing.
Principles for determining keywords
1) imagine which keywords he will use for retrieval from the perspective of the searcher.
2) related to the homepage content.</
