javascript - It is said that 301 redirect is good for seo, but what about cn or net domain names?

Question

Most websites like to 301 jump the domain name without www to the domain name with www..

But for domain names with net and cn suffixes, should they jump to com? Or jump to the corresponding domain name?
For example: xxx.net xxx.cn If you do a 301 jump, it will jump to www.xxx .net www.xxx.cn?
Or when the user enters xxx.net xxx.cn, 301 jumps to www.xxx.com?

Answer 1

xxx.net, xxx.cn and xxx.com are three different domain names. Why are they considered to jump to each other? Do you have both? If you do have both, then choose which domain name you mainly recommend

But I think your question should be that when customers visit xxx.cn, they have to 301 once to the www station, so at this time they usually 301 to www.xxx.cn

The same applies to customers accessing xxx.net, then 301 goes to www.xxx.net

The same applies to customers visiting xxx.com, then 301 goes to www.xxx.com

Answer 2

The general recommendation is .COM. Because most ordinary users are only used to entering .COM
