What is a high-authority domain? What does "high-authority domain" mean?

Many people have these questions, so let's explain them in detail below.

What is a high-authority domain?

A PageRank (PR) domain is one that has been used by someone before, has been indexed by search engines, and thus possesses a certain level of authority. Such domains are more valuable than domains without authority. Using an authoritative domain for a website makes optimization easier, and the website ranks higher.

Authority refers to Baidu, while PageRank refers to Google. Not all old domains have high authority, and those with negative records have even less so… Generally, authority is determined by factors such as the domain's indexing, snapshots, backlinks, and traffic.

An old domain doesn't necessarily have high authority. If an old domain has never been used, it cannot have authority.

A domain's authority determines its value, and it is closely related to the quality and traffic of the website that owns the domain. High-authority domains have higher responsiveness.
