PR is Google established PageRank, he is designed for the site to play a scoring role, usually we are the webmaster add links, also has the other side of the PR as can be added to the judgment of one of the conditions.

But if the PR can also be false, you believe it? Recently, some friends want to exchange links with me, because my personal site PR has been 6, so I will also go to see the other side of the PR, but I found that these Alexa rankings in the millions of sites, PR unexpectedly has 6 7, and even 8, I'm sure there's something fishy in this.

Read the relevant information, I am probably aware of this fake means, they will be a domain name through 301 to some PR higher web site, when the search engine updates the site PR, their site also updated, at this time, and then turn 301 to cancel. So we see a PR of 7 to 8 of the "Small Web site."

So how to identify the authenticity of PR? I have sorted out the following methods.

1, use the Web page snapshot: If the page snapshot and browser browsing page inconsistency, then this station used 301 turn.

2, the use of link instructions to see if the web search records are consistent. As shown, we can see that site a (left) to the site B (right) of the hijacked, their content consistent, PR consistent.

3, if the new people think the above method is very cumbersome, I suggest a novice friend to use some of the professional site to identify PR true and false, in the search engine input "identification PR true and false" can find a lot of the site to identify PR true and false.
