What does the extension ".com" typically indicate about a website?

The extension ".com" typically indicates that a website is intended for commercial purposes. This designation originates from the word "commercial," and it was one of the original top-level domains established in the Domain Name System (DNS) in the 1980s. While ".com" domains can be used by various types of websites, including those not associated with businesses, they are predominantly linked to companies or organizations seeking to sell products or services online.

This is why ".com" has become the most recognized and widely used domain extension, representing businesses, e-commerce websites, and various online commercial entities. When users see a website with a ".com" extension, they often expect it to be a business rather than a personal or non-profit site, which are more commonly associated with other domain extensions like ".org" or ".net."
