Before I heard the word black, but only to hear, think about just some people with hacking technology in doing SEO, those people always have some way, do we these white hats do not. A few days ago I found a single page station in one of my stations, although it is not a hot keyword, but at the same time do Baidu, Google's home page, ranking only in my station below, the fog is very curious about this single page of the station in the end why can row to Baidu, Google's home page.

So I studied, first I used Baidu to see the link to the station, found that he has about tens of thousands of of the link bar, almost all from a few stations of the whole station link, so I opened a link to that site several stand up to see, and did not find links, so I opened his source code, in the inside check his link

As a result, a string of code was found

<marquee onmouseover=this.stop () Onmouseout=this.start () scrollamount=1 direction=up width=1 height=1 "1" >
<a href= "..." title= "..."......... >.................</a>

</MARQUEE>

.................

The function of this code is that you can not see the link on the page, but the search engine is able to search, that is to say, search engines to determine that these stations have his outside links.

The fog didn't intend to publish the code, but the fog didn't like the hacker friends, because of the fog shadow of the company's website, please a network company to do, that the company's procedures security is too bad, and more loopholes, fog shadow themselves are lazy to fill the loopholes, helpless, those hackers you come in also came in, but also like to change the home page, Every time they mend, I'm going to change back.
