For spam links (SPAM) a lot of webmaster disdain, that this is no big deal. Isn't it just a few spam links? But I don't know what it's hiding behind. Below we use the form of examples to illustrate the harm of the garbage link hidden behind.

First, import the junk link.

Importing junk links is a typical hidden wreck in the cumulative process of spam links. You will find that it has a certain help to the weight of the whole station, because he has not been identified by the search engine program as garbage, in the process he and most links are identified as health links. Once it is captured by an anti-spam program (ANTISPAM). will be based on your number of spam links to calculate and reduce the weight of your site and included. Harm to the important person even be plucked hair (such as Baidu).

Example: illegal type of site is mainly rely on black link import, a large number of sites have been down the right and by K, a large number of sites hidden dangers. No URLs are listed here.

Second, export the junk link.

Export spam links refers to the general forum, BLOG, SNS, navigation and other sites. They can be random replies, messages, write articles if not timely treatment of the site down right is extremely scary.

For example: seowhy.com, Seobbs.net, linkhelper.cn (in order not to export the link without the WWW)

Third, the garbage link can be used to harm others.

The answer is no, first, the spam link can not be identified at once, especially you import link link can not be recognized at one time, and the import of the spam link is a cumulative process, he needs up to 6 months to 1 years, and will only reduce the keyword ranking, included will be a certain degree of decline. and is recoverable. Recovery period (2 months). I have done experiment site (trial period 6 months), now the domain name has been deactivated, traffic once as high as 10,000, included up to 22,000 (Baidu). Imagine if you can use such a long time to harm others, then you directly DDoS his site, the effect will come much faster, and others can be restored, steal the chicken does not eclipse the end of the rice. The Junk Link K site is the result of an export spam link. Is the station is the person to reply and clean up the rubbish link, this kind of link harm is greatest, of course time restores metaphase also longer. But the link is artificially controllable. So the webmaster must regularly clean up the site, especially now a large number of mass popular.
