Today habitually open AD5 website to see news, just found scroll introduced this PR has been updated, I hastened to open my station home, a look! Unexpectedly from 5 has dropped to 4. In the open website links on the site, found that most of the drop, even overseas Chinese well-known "fighting in France" also dropped. The Overseas Chinese website PR has not changed also in the majority. At the same time found that the disappearance of a lot of sites, should be with the domestic "one-cut" related.

Count several representative overseas Chinese websites:

"Fighting in France" PR6 to PR5 http://www.xineurope.com/

"Poor Tour" PR6 not changed http://www.go2eu.com/

"Polish Chinese Information Network" PR5 dropped to PR4 http://www.plchinese.com/

"Belarusian Chinese net" PR4 not changed http://www.chinabelarus.net/

I do not understand so much SEO technology, I only know that these sites are the daily original content more frequent updates, but this time the PR update is so strange. I do not want to go to understand more SEO, I just want to do a good job in the site, service to people this is the meaning of the site.

For the PR is not the most important, now see the domestic will be on the site "white list" system, the overseas site does not face the record of domestic users can not visit, most of the overseas sites are personal sites, who can afford the company 1 million registered capital AH. If the domestic shielding, so at least to the overseas Chinese website caused by not less than 50% of the flow loss.

Overseas webmaster needs to seriously consider, in the face of such a crisis, we will go?
