If an advertisement or icon on your site is made in Flash to enhance visual effects and embellishment, that's not a big problem. But if your site is full of large Flash files, it constitutes a spider trap, the page effect may look gorgeous, but the search engine may not understand, can not be included. If the site starts with the Flash animation title, and after watching the beginning, there is a real html version of the text site home page, but the search engine can not read Flash, there is no way to enter the back of the html site.

Solution:

1. You can already do a good look with CSS, try not to use Flash as a website.

two。 If you have to use Flash, add a page to the html version on the home page, such as the html version of the navigation bar on the home page, and Flash in the following page.

Second, all kinds of jumping spider traps

Only 301 turn is the favorite of search engines, other turns are to make search engines alert, such as 302 jump, JavaScript jump, Flash jump and so on. General web games, yellow sites and other ads like to use this to deceive search engines, such as users are automatically redirected to a game page when they visit the home page.

Solution: try not to use a diversion other than 301, such as a location-based jump, but only if your site has a high weight in the search engine's mind.

Third, the spider trap of the frame structure

Frame structure: click on other description text links of the page to change the page, but the URL of the page remains the same, this is the frame structure, such a website search engine can not be included.

5. Session ID Spider Trap

Some websites use sessionID to track user visits, and when each user visits the site, a unique sessionID is generated and added to the URL.

If every time a search engine comes to this site, it will be treated as a different new user and will generate a different session ID URL. The search engine needs to determine whether it is a normal parameter or a different session ID. Search engines are either unwilling to include or include different URL, but it is actually the same page, which will cause a lot of copied content.

Solution:

1. Tracking user access should use cookies instead of generating session ID

two。 If you must use session ID, then use the program to determine whether the visitor is an ordinary user or a search engine spider.
