analyze and solve problems


analysis, found that keywords ranking is not immediately dropped after 301, but first almost all transferred to the new domain name, and then one or two months later began to decline, and began to become more and more serious. Looking back on the process, it was discovered that there were several problems with the site:

1, there is an absolute number of old domain names on the template, resulting in a large number of export links after the new domain name is switched.

2, a lot of dead links on older, older pages.

In the months following

3 and 301, the links were removed (because the weight of the old domain name was missing).

then did the following solutions, starting with the rescue:

1, modify the template, replace the old address to the new address, and regenerate all pages.

2, change the old column template to the new template, and regenerate all the pages.

3, arrange the chain Commissioner contact each link, modify to new domain name

4, in addition, continue to strengthen the new exchange chain.

so, what is the reason for the large number of Links 301 redirect after the decline? The reason is very simple: because after 301, many Links links on the site is our old domain name, and the weight of old domain name changed to 0 (the webmaster tools), so this time a lot of friendship chain.
