I. Framework structure.

I can only say that if you still use the frame structure on your website, then I suggest you cancel it quickly. Although the frame structure for the maintenance of the site and update has a certain degree of convenience. However, it is not conducive to search engine spiders crawl. This is one of the factors that are not popular in the frame structure.

Second, Flash.

Some stationmaster in order to let the website visual effect wonderful unusual, they are on the website whole a big chunk flash. But this also caused the spider trap. Because search engine spiders crawl only HTML code, just a link to the Flash file, and no text content. No matter how beautiful you may look, it is a pity that the search engine does not see it and cannot index any text information, so it is impossible to judge his relevance. Therefore, we should try to avoid or reduce the use of flash.

The so-called dynamic URL means that the URL contains a question mark, an equal sign, and some parameters, and so on. Generally speaking, dynamic URL is also unfavorable to spiders crawl, we should avoid.

Six, a variety of jumps.

Search engines are more sensitive to jumps. Inferior: 301 Jump, 302 jump, JavaScript jump, flash jump, Meta refresh jump and so on.

If you have to jump, the search engine is recommended to use 301 turn. Other jumps are bad for search engines, just because some black hat SEO often uses a turn to deceive search engines and users. So do not use other jumps without being compelled to do so.

Seven, request to login.

Search for the vegetarian spider he will not fill in the username, password, authentication code. Then your content will not be discovered by him.

Compulsory use of cookies.

Some websites want to remember the user's login information, track access path, etc., mandatory to use cookies.
