What is Google Adsense Update about subdomain blocks will be promoted to the domain level  in three days?

First all we discuss, what is a sub domain?

A subdomain is a subset of a larger domain name that is used to organize and categorize website content. Sub domain S are often used to create separate web sections for different purposes or audiences, or to distinguish between different types of content on a website.

For example, a company might have a main domain name of “example.com,” and create sub domains such as “blog.example.com” for their blog, “store.example.com” for their online store, or “support.example.com” for their customer support section. Each of these sub domains would have its own unique content and functionality, but would still be part of the larger “example.com” domain.

Sub domains are typically indicated by a prefix added to the main domain name, separated by a dot. The subdomain prefix can be anything the website owner chooses, such as “www,” “blog,” “store,” or “support,” among others. The full domain name for a subdomain would be in the format of “subdomain.example.com”
