For the site, the replacement of server space because of the inevitable problems encountered, and this can be a lot of reasons, such as server attacks, server instability, domain name for the cancellation of the file is not for a reason, and so on. However, the replacement of the server if the improper operation of the search engine is very easy to punish, such as snapshots, included stop, ranking decline and so on a series of changes. To this end, leaflets to share the previous change of the server's war, as a cautionary tale.

Leaflets before the Internet pioneer opened a proxy platform, due to the domestic server access speed is not very good, telecommunications netcom problem, so later on the replacement of the Hong Kong server space, can be replaced after the sad reminders of the matter will follow. We first take a look at Baidu's proxy platform for the collection of the history of the site:

Today again site to see:

And for the agent platform site's main keywords have fallen to hundreds outside, although the site is not the main keyword originally high, but at least in hundreds.

Reason Analysis:

The replacement of the server space is bound to resolve the domain name to the new IP, but Baidu has its own DNS cache server. When the site domain name resolution to the new IP, although the domain name has been correctly pointed to the new IP address, but the Baidu cache domain name is still the old IP, causing Baidu spider crawling is still the old server. But because the leaflet has stopped the old server space running, so that when the spider crawling site errors, and then there are a series of sad reminders.

For this, the leaflet gives four-point server space replacement recommendations:

(1) To ensure the normal access to the site

After replacing the server space, the search engine will give the site a period of time for observation and review. Therefore, we must ensure that the domain name can be normal access and timely add Sites 301, 404, because the site will inevitably appear in the replacement process can not be accessed.

(2) Data backup and transfer

The data for the website must be backed up to ensure a complete Web site program and database for unforeseen surprises. At the same time, the backup good data uploaded to the new server space, to avoid missing files caused by the Web site run error, it is recommended to upload the FTP tool, so even if the upload is unsuccessful, the file will remain in the queue.

(3) High quality content and external chain release

As mentioned above, replace the server space after the search engine will observe the site, at this time we should try to take the original way, to the site for high-quality content updates. After the update after the high quality of the chain release, such as high weights or related to a strong forum, and so on, so that the spider to guide.

(4) Monitoring Spider crawling

After the replacement of the server space, the log and statistics, control the spider in the crawl every time, observe the 3rd on the content update and external chain publishing operation is effective, search engine has completed the new server space observation. And if found bad situation also good in time to adjust. However, the server space at the beginning of the change, because the spider has not yet adapted to it, so the crawl is relatively small. To this, the mentality should remain calm, adhere to do a good job content update and external chain release.

Finally, a small reminder, the search engine domain name IP address DNS has a certain amount of time, so the old server space should still maintain normal operation for a period of time, until the search engine can normally include the new server space content so far. Avoid the Q575935353 of the leaflet (if you have any questions, you can communicate well). And then do the above, leaflets believe that the replacement of server space will not be so hurt.
