What kind of website uses keywords to locate content?

A search engine is designed specifically to locate content using keywords entered by users. When a user types in a query, the search engine scans its indexed database for relevant pages that contain those keywords. It employs complex algorithms to rank these pages based on several factors, ensuring that the most pertinent results appear at the top of the search results.

In contrast, the other types of websites serve different purposes. Blogs typically focus on providing articles or content written by individuals or groups, which may be organized by topics but do not primarily function as tools for searching content across the internet. E-commerce sites are structured to facilitate online sales and often feature products or services, but they do not search for content using keywords in the same way that search engines do. Portfolios showcase an individual's work, such as artwork or professional projects, and are more about displaying content rather than searching for it. This highlights why a search engine uniquely fits the description of using keywords to locate content effectively.
