Baidu 301 redirect test grassroots webmaster 4 months of research results

Baidu 301 in the end there is no use, how long will it be useful? Most of the webmaster will encounter this problem, because sometimes inevitably encountered change the domain name problem. I do a more than 4 months of the Baidu 301 test, basically recorded every time ranking changes, now the end of the experiment, the test results will be announced, and do a simple analysis of the data, I hope to help the webmaster have the same problem:

1. Test the basic situation

1, test the original domain name: www.yang999.cn (the following content is replaced by website A)

test target domain name: www.jianzhiwangzhan.com (the following content is replaced by website B)

site A did 301 to website B.

2, A domain name opening time: April 19, 2008

B domain name opening time: December 28, 2010

3, opening 301 hours: December 28, 2010

4, test Keywords: online part-time (that is, each time the so-called rankings are based on Baidu search online part-time ranking data prevail), 301 ago, A in Baidu’s ranking has been in between 15-35.

5, test end time: April 23, 2011

6, test time span: 4 months, and many webmaster said more than 3 months, 301 stable, not far.

7, the end of the test: the B website "online part-time" ranking has long-term stability in between 15-35, reached before the A website, A DNS and lifted in April 12, 2011 301 after a few times to update the site ranked no change. Currently, B site Baidu included 433, has reached the level of the previous A site.

two and several reference conclusions

I’m doing 301 period, basically adhere to update an original article every day, the chain to do less, and now only 240 YAHOO chain.

(a) 301 useful for Baidu, can transfer weight, for the following reasons:

1, 301 after only a week, B site in Baidu will have a ranking, do not do 301 of the new station is almost impossible.

2, B website did not go through the Baidu inspection period, did not enter the sandbox, generally speaking, completely new sites have a Baidu sandbox period, but the B site does not, can certainly be 301 played a role.

3, B website snapshot has been in 1-3 days, and to maintain the content of the continuous, completely new sites, usually included in the home page, there will be a long time, not included in the page.

(two) for a fairly long period of time, new and old domain names will be in Baidu rankings
