When it comes to hanging black chain may be a lot of people will be linked with the horse, in fact, both are the same thing, through the invasion of the site to tamper with the code, but the contents of the changes are different. Hanging a horse As the name suggests is a Trojan horse, we all know is actually a virus, nature is to the computer or the site has different degrees of disadvantage, I used to be a business station Zooey was hanging Trojan, each time one opened automatically run a script program, the computer running speed to the slowest, so the computer instantly jammed, the browser crashed, Computer at least more than five minutes before beginning a little reaction, in exchange for someone else to encounter this kind of Web site for the first time to kill will not come the second time.

Following the combination of several sites I have been hanging black chain and hanging horse experience (because of hanging black chain and hanging horse is one thing in nature, here on the black chain as an example), analysis how we can detect their own site is hung black chain it?

1, the site in the search engine performance anomaly. This specific performance for the site included, Baidu snapshot update and keyword ranking above, you may feel that these performance Baidu update can also lead to, but if your site content outside the chain is not a problem, general update will not be so, if your site content quality and quality of the chain has declined, So after the update of your website performance is also understandable.

2, to see if the site source program has exception code. Hanging black chain is generally in the home page to add a large series of hidden links, these links in the foreground is not visible, the surface may not see the site has been hung black chain of signs, but that does not mean that your site has not been passive hands and feet, as long as you see the source code will have a surprise waiting for you.

3, check whether there is an abnormal link link exists. For SEO friends to check the links should be a potluck, because often check friendship whether there is a site is down the right or by K, if you check out the abnormal links, or you check out the number of links suddenly increased a lot, then these suddenly out of the link is very likely the black chain.

4, view the Site page modification time. We all know that in the computer to create a new file or any edit a file, will display the last time of editing, the site is the same, the general situation of the final page file editing time is the last time you upload, if not modified after uploading, then all pages of the last modification date should be the same day, Can through the FTP tool or into the virtual host management background into the webftp to view the change time of the page, if there is an exception to indicate that your site files have been modified.

Since you know how the site is linked to the black chain, then the solution can only be the right remedy:

1, more observation of the site in search engine performance;

2. View the source code of the website more;

3, the habit of regular check links or dead links;

4, modify the Web site permissions or the occasional change of FTP password;

5, if your site does not specify description, then we should pay more attention to the contents of the snapshot page crawl, perhaps crawling content inside there is black chain content, I met this is the case;

6, if the site is a shared IP, the need to regularly check the same IP site is normal, preferably with an independent IP, to minimize unnecessary interference.

Black chain is a big blow to the people who do SEO, finally put the station all aspects to do a sudden to you hang black chain, let you suffer from it, light point may be temporarily down right, serious point of direct by K, do station is not easy, need to take a good grasp.
