Changing the server is a "big deal" for optimizing the website, it directly affects the impression and weight of the site in the search engine, and try not to change the server unless you have to. If you really want to replace the server, you should also pay attention to the following steps:

1. Now that the server has been replaced, the premise is to ensure the quality of the replaced server. Needless to say, you know.

2. Make a complete backup of the site, from the database to all programs, picture files, page files, etc.

3. Set the TTL on the domain name server (DNS) for a short time, so that all ISP and search engines will view DNS information at any time instead of using the IP address in the cache.

4. Upload the file to the new server, change the domain name server, and re-resolve the website to the IP address of the new server. At the same time, keep the old server running properly, because there is also a weight transfer problem.

5, check the site links, remove the dead chain, etc., for individual may use 301 jump.

6. Check the log file of the server (mining the seo optimization method from the spider crawl log) to confirm whether the search engine spider crawls the page on the new server. Generally speaking, domain name resolution takes three days, but it is best to wait a few more days for security reasons. When spiders stop crawling the old server and crawl the new server, it means that the replacement of the server is complete.

It is important to note that during the whole process of changing the server, we must ensure that the website can be accessed properly. In this way, spiders will not crawl your site with a dead chain and return invalid links. Now many space merchants provide "website moving" service, webmasters can learn more about it.
