As we all know, Google PR is a important thing which webmasters in pursuit of, though not necessarily with the rankings, but the little light green on the toolbar,let peoples exciting.
Today,Mr.Cubo is to talk about the PR hijacking, which is used deception to obtain the toolbar relatively high PR value. Method is to use Jump pages.
In general search engine to deal with the 301 and 302, are the real target should be included as a URL’s URL. Of course there are exceptions, but in most cases this is dealt with.
So if you do A domain name from the 301 or 302 Jump to domain B, B domain PR value is relatively high, in the domain A PR update, the domain B will also show the value of PR. Some people take advantage of this, their PR value of domain names deliberately raising.
At first Jump to 301 or 302 high PR domain B, such as after the PR update, to cancel immediately, put their own content, and then start selling links. This bogus value of PR at least until the next PR update, generally have two or three months time.
Other webmaster came to this site, see a high PR value, but do not know the value of PR is to get abnormality way,the PR value don’t of this site, but another site.
A other way is to use the programme avoid Google’s spiders, to return to 301 or 302, for ordinary visitors and other spiders are content to return to normal. So that we see is a common site, only to see Google.
For example, below this PHP code to achieve this effect:
if (strstr($_SERVER['HTTP_USER_AGENT'], “Googlebot”)) {
header(”HTTP/1.1 301 Moved Permanently”);
header(”Location: http://www.apple.com/”);
exit;
}
else {
header(’Content-Type: text/html; charset=ISO-8859-1′);
};
?>
Here start ordinary HTML code
I do not know programming, just above probably mean, not necessarily accurate.
Both are means of PR value, not their own domain name is the real value of PR. The purpose get the PR value is very obvious,for link sales or RP sale. If the sale is the link to the aspirations of the ad click traffic, the situation may be, if the aspirations of the main or the only demand is high PR value, which undoubtedly is deceiving. This site links to the PR value of no contribution.
So how to identify the PR value of deception?
The most accurate of course, is to see Google’s snapshot, if you see that the page is a kind, Google is the snapshot to see another site, the general site title and logo will show, and I am afraid this is very suspicious of.
Another noteworthy is that the links to find and buy time, if the other side of the show is a high PR value, must be very careful. Links should be to establish the relevance of the content of the main considerations for, PR ranking of the actual level of impact not many people thought so important.
