Google and Baidu: 301 redirection index record observation

27th day of last month to set the redirection,/about/www-clin003-com-390.shtml now to see the index of the search engine:

Google:

About97Item conformityWz.mygogou.comThe query result.1-10Item (when searching0.37Seconds)

Clin003.comAbout449Item conformityLin's SpaceThe query result.1-10Item (when searching0.36Seconds)

About2,650Item conformityClin003.comThe query result.1-10Item (when searching0.07Seconds)

Because the domain name "clin003.com" already has content, it seems that there will be more indexes. I useLin's space isThe results of the Restricted Search are the content indexes of this blog.

Baidu:

Site: clin003.com Lin's space-Baidu: 25 related webpages in 0.052 seconds

Site: wz.mygou.com -- Baidu: Click here. Find the relevant web page, which takes 684 seconds.

Compared with Baidu, 301 redirection is not very popular, because after 301 redirection (the time is not accurate to the specific length) no result page is displayed on the home page of wz.mygogou.com (generally, the home page is at the first record position ). The Baidu can now see that wz.mygou.com is in the first position, and the keyword exclusive to this site also finds that Baidu is dominated by wz.mygou.com, while the clin003.com is omitted. See:

For comparison, take another picture:

Obviously, Baidu has a problem with 301 redirection: clin003.com (the targeted destination domain name is used as copy), which may lead to Baidu penalty (only conjecture, even though this blog has little content, I still don't feel it !!), Maybe Baidu's delayed indexing of the new content of clin003.com is a sign.

Relatively speaking, Google soon made a better deal on 301 redirection content: At least searching site: wz.mygou.com has fewer index records (that is to say, most of them are converted into index records of clin003.com ), however, this may also be related to the sitemap file I submitted in the administrator tool (hopefully Baidu can also provide such a tool to supplement the Baidu index policy ). It should be said that Google did not continue to update wz.mygou.com after finding wz.mygou.com 301 switched to clin003.com. (I'm not sure whether wz.mygou.com will be updated if the ingress is not fully redirected to clin003.com, it's just possible to hit the token)

Check the header information of wz.mygou.com (Detection Method ):

The following is a supplement:

Site: clin003.com

It seems that Baidu prefers to put the "directory page" on the top !! (..)

This figure shows the time difference between the crawlers of Baidu? I remember what I captured very quickly in the past. It was captured almost every day !! Of course we can see from this time. This interval is a bit large !!
