January 18, 2013 Baidu Webmaster Platform released a message, said recently some sites use Baidu jump link for black chain, the way will be ineffective. and call webmaster attention to site security, at all times to carry out security monitoring. Thus, the term black chain was pulled to the front. In fact, these years, about the site hanging black chain case is not much, because we all understand that although the black chain can quickly improve their ranking in a short time, but for the long-term development of the site and snapshots and other daily data does not make any sense, so most webmasters no longer play this attention, Just some dozen edge or is yellow net webmaster also use this kind of quick means.

Although the black chain in the webmaster Circle of influence no longer strong, but as a general webmaster I think we can harm the heart must not have, the heart of people can not be, by others hanging black chain is not a good thing, for their own site is also the impact of the existence of a comprehensive understanding of the black chain is still very necessary. Then the black chain is generally through which several forms to insert, usually by adding a CSS style to the site source code to achieve. Its means are mainly divided into four categories:

1 Set the Display property to none, so that the site link information is not visible externally.

2 or set the link character to infinity to achieve the goal of deceiving the past.

3 link characters and Web page background color consistent or similar to reach the link is not visible.

4 through the link position positioning, so that links appear to the visible screen, to achieve the black chain effect.

Recognize the black chain operation of the basic methods, then we should use those ways to accurately determine whether the site is someone else hanging on the black chain?

A regular view of the home page source code is a more effective measure, very simple in fact, just click on the page to select the source file on the line, for this detection method can remove the black chain appears most of the home page, will be unfamiliar link removal hurriedly.

B about Webmaster Tools, we must not only consider it as a test site included functions, in fact, the dead link detection inside is also very useful, at least to find all the links on the page, and identify which links can be accessed, which links inexplicable existence, and for those unfamiliar links, pretty is black chain.

C Clever use FTP upload tool, under normal circumstances, space in the site space to modify the time is the most of our operation, and if you find that the files in the folder have a lot of changes to the same or short distance that day, then the site may be linked to the black chain, this time we have to transfer the corresponding files to the local computer , and then see if there are unfamiliar links in the source code, but the asp+access site, except for the site, because this program is relatively strong immediacy, such as your website article has a statistical article clicks, visitors to browse a website article, that will be written to the database, The database modification time is naturally modified.

D often modify the FTP upload tool or website backend users and passwords, after all, too simple password will let some shifty caught the chance of committing a crime.

E sometimes sites are linked, not all of us are not careful to fight themselves, use webmaster tools in the same IP site query, will be under the server to detect all sites, see whether there are other sites have their own this situation, if there is, then you can be sure that the site space service provider security testing there are certain problems, Should be reflected in a timely manner.

In fact, to ask the black chain in the end has no effect, I think a lot of webmaster friends is ambiguous attitude, because some people in the industry want to make smart money is always shouting high risk, high returns, in fact, black chain from a certain sense, for our site help is not very small, very simple truth, if your site never updated original content, is hanging 1000 high weight high PR black chain, your ranking will become the first? If a friend of the black chain or the existence of luck, then the author said a little more.

Baidu many times the update, has made it clear that the black chain is a means of cheating, Baidu once found will be a crackdown on the site, or even pull Mao K station.

Black chain is a dirty business after all, once the black chain of friends found, will definitely delete the link and report, even if you spend money to let some so-called have the strength of the company to give you a guarantee of the number of black chain, then he supplies your black chain is likely to be a link to other sites, for our own website building without any benefit.

A site with a high PR value since you can sell it, also absolutely can sell to others, if not believe, you can query this site source code in addition to your links and what, there will certainly be many, according to the cake principle, even if this link is useful, then the weight can be divided into your 0.

Black chain is a consumption of resources and energy consumption is not necessarily the benefit of the money, if the destruction of important sites, then there may be the possibility of illegal, or do not do well.
