1,js Cheat Form
The so-called JS form link, is in the link place, not in the page put on the link, but put a JS file. We should know that the search engine is still unable to index JS files. This method may be rarely used now.
Solution: As long as you are linked to the site of the page, view its source files, if not found your links, such as "< a href=http://www.xxx.com > your links </a >" such as the text, But in the link place has a xx.js such file, then is the JS form.
2, Frame cheat form
This method and JS form has a similar place, but, the JS file replaced by a frame.
Solution: With JS cheat form of the solution is similar, but, you see no longer try JS file, but a frame in the form of a page.
3,rel= "nofollow" cheating form
This form is to tell the search engine do not give the link weight, if the link is changed, equal to the same.
Solution: If you look at the source file of the page of the site you are linking to, see the words "< a href=http://www.xxx.com> your link </a >". However, in your link also added rel= "nofollow". Become "< a rel=" nofollow "href=http://www.xxx.com > Your link </a >". So the link is in exchange for worthless.
4, through intelligent DNS resolution
The most basic function of DNS resolution is the ability to intelligently judge the users who visit your site, and then resolve your domain name to different IP addresses according to different visitors.
If the visitor is a netcom user, DNS resolution server will be your domain name corresponding to the Netcom IP address resolution to this visitor.
If the user is a telecommunications user, the DNS Policy resolution server resolves the IP address of your domain name to this visitor.
In other words, when the user visits, see, there is always a normal link. For example: "< a rel=" nofollow "href=http://www.xxx.com> your link </a >".
If the visitors are spiders, such as Baidu's unique IP, give it a link without your home page, so, that is to tell spiders, my site did not put links. The weight of its site can not be divided.
Solution: As long as in Baidu input with you linked to the site URL, and then, point that URL behind the Baidu snapshot, to see if there is a snapshot of your link. If not, it means cheating. In other words, Baidu to that site photos, there is no link to you. But when you visit his site, you can see that this is the way to cheat.
5, Code cheat form
Code cheating, and smart DNS cheating has a similar place, but also by judging the caller's main nose to determine whether the visitor is a spider, if it is a spider, do not show the link. The code that the ASP language implements is this:
<%
function Getbot ()
' Query spider
Dim s_agent
Getbot= ""
S_agent=request.servervariables ("Http_user_agent") ' critical judgment statement
If InStr (1,s_agent, "Googlebot", 1) >0 Then
getbot= "Google"
End If
If InStr (1,s_agent, "Baiduspider", 1) >0 Then
Getbot= "Baidu"
End If
End Function
If getbot= "Baidu" or getbot= "Google" then
Response.Write "will not show you ″ ' spider visit Remove friendship link, hehe
Else
Response.Write "< a target=_blank href=http://www.****.com >seo tutorials </a >" ' Common people see, links normal display
End If
% >
Solution: This method of cheating with the fourth kind of DNS intelligent judgment is the same, is to see the site of the snapshot whether there is your link.
