Recently received two consecutive cases of alarm, the site ranked well, there is no big change, suddenly in Google search is not. The first page of the previous search point, now turn dozens of pages is difficult to find.

And carefully check these sites, found included, update all basic normal. Apparently fell into Google's sandbox. Through communication with the technical staff and inquiries, know that the discovery of several sites of this situation coincided with the change in the rankings soon before the server space changed.

Case 1: A Network Marketing class site. Due to the space due in China channel, in order to save the cost, the site moved to its own server, moved less than a few days, the site in Google almost disappeared, search all kinds of words are difficult to find. Baidu, Yahoo Normal.

Investigation of the reason, found that the company has built dozens of sites, mostly on their own servers, the network marketing site to obtain a large number of connections from these sites. When space is transferred, all of these connections become connected to the same IP as the site itself. As a result, Google quickly lowered its connection importance and entered the sandbox. But after the transfer, other site rankings have no effect.

Case 2 a Ticket class site. After the service period expires, the space is transferred to its own server. Upon completion. The website has entered the sandbox. Similar to Case 1, there are many sites on the server that belong to his company, and the style and content are relatively close. are connected to each other. After the transfer, all site rankings on the server were affected.

Information on the above two case responses:

1. From a large number of other same IP of different Web sites, for search engines still have some effect. The concrete function needs further proof.

2. If it is from a large number of sites with the same IP connection, it may be a certain degree of Google penalties, such as access to sandbox. But Baidu and Yahoo did not see any impact from the case.

3. The replacement of the server on the site itself or the transformation of the site server with a large number of connections to the site will have a certain impact on the rankings.

4. If the station starts, it gradually obtains a large number of connections from other sites on the same server. Google will not punish these sites, the connection is still useful, but no other IP connections so the impact is obvious.

5. Sandbox with the site's external connection structure changes have a significant relationship. As long as the external structure of the site changes significantly, the site is most likely to fall in. The rapid increase in connectivity, rapid reduction, a large number of connections quickly IP should change, suddenly other connections have become the same as their own site is the same IP. So I guess that sandbox may not have the most direct relationship with the number of external connections, the most important thing is the change of the connection and the trend of movement, is not natural and reasonable.
