What is the difference between a domain name with www and without it

It doesn't make a difference, the .com suffix is the top-level domain. Lots of ** will resolve their own domain names these two, with www and without www, so that users can access any of them by entering them at will.

When doing domain name resolution, you should set a domain name without www. In this way, when users use a domain name without www, they can access your ** normally.

We talked about the concept of URL standardization, in the eyes of search engines, URLs with www and without www are two different URLs, when they point to the same **, it will make the search engine not understand which URL should be selected as the main one. Therefore, we recommend that some eligible hosts use 301 redirects for URL standardization.

Domain names with and without www are the same for search engines, choose one of them as the main domain name arbitrarily, and use the main domain name when linking internally and friendship, so that the PR value will not be scattered.
