Spider traps are webmasters in the design of the site used by some search engines do not like, not conducive to the search engine's day-to-day practices. Success to avoid the search engine spider traps from each spider trap specific analysis, to come to the correct method.

The most common spider traps are as follows:

1, the website dynamic URL

Many dynamic URLs are due to automatically call the database, so that the site automatically generated by a lot of parameters of the URL, in general, search engine spiders do not like the dynamic URL, because the dynamic URL parameters too much, search engine spiders crawl efficiency will be greatly impaired, we should do a good job of static Web site URL.

2, various types of jump

When users visit the site, they will be jumped to other pages for no reason. If it is according to the user's information to jump, then will not cause too much impact, once it is indiscriminate jump, then will cause a large number of users disgust, thereby losing effective customers. Common users are disgusted with the jump: JS jump, Flash jump, 302 jump, and so on, we try not to use these jumps.

3, JS generated navigation

Many websites like to use JS, because JS can give the site a strong visual effect. Some sites like to use JS generated site navigation, which in search engines seems to be very annoying, after all, it can not identify JS internal links, we only try to make the search engine's crawling work to simplify, in order to get the search engine's favor.

4. Member Login function

Some site content will be in need of membership or user login to see, this part of the content even search engines can not crawl and crawl. We know that search engine spiders will not fill in the user name and password to access the page and then crawl its content, which significantly increased the difficulty of the spider work.

(5) frame (frame structure)

If a novice webmaster does not know the frame structure, then you can rest assured. The website is designed according to the frame structure to be able to maintain the update page effectively. When a search engine accesses a Web site designed for a frame structure, it only captures the code of the HTML file, and no text information can be crawled, so the search engine cannot identify the site's content. Do not waste time waiting for search engines to change their own to adapt to your site, but to change their adaptation to the search engine.

6. Session ID

Some site users will automatically generate a session ID when they visit, which is present in the URL. Every visit by the search engine automatically generates a session ID, which is bound to result in a different URL for the same spider's multiple visits. A page many times by spiders crawling will cause different URLs, the same content. This is the search engine seems to be repeated content, then your site is not far from the right to fall.

7, the use of flash

Reasonable use of flash technology is also very important, simple use of some small flash to do some special effects to increase the beauty of the site is still possible. If the whole site is a flash, then will not be indexed by search engines. At present, the most powerful search engines do not recognize the contents of flash, so the site is not to mention optimization. Standing on the optimization point of view, this is a dead stop. So do not use Flash to design the site, you have to use Flash to show the information and strength of the site, then this kind of site does not need to do optimization bar.

8, automatically add site collection

This is the most annoying of both users and search engines. Because add a favorite link is the user's own rights, you are mandatory to add links to users will cause users disgust, once the site link added unsuccessful will also cause users and search engines can not normally visit your site.

The above is the most common eight spider traps, to avoid these traps in fact very simple, as long as you rookie webmaster do not use these technologies to design the site will not fall into these traps inside. Rookie stationmaster must understand these traps, this can be to your growth to provide huge help, let you truly become qualified seoer. (article from: www.amlh.cn)
