Online directories are websites that list information about various businesses, services, or individuals in a structured format. They often categorize listings by type, location, or industry, making it easier for users to find what they need. Examples include Yelp, Yellow Pages, and Google My Business, which provide details like contact information, reviews, and hours of operation. These directories serve as valuable resources for both consumers and businesses. For consumers, they simplify the search for local services or products, while businesses can enhance their visibility and attract new customers by being listed.
