Yelp is an online platform that allows users to find and review local businesses, such as restaurants, shops, and services. It provides a space for customers to share their experiences, rate businesses on a scale of one to five stars, and post written reviews. This helps other users make informed decisions about where to eat, shop, or seek services. Founded in 2004, Yelp has grown to include millions of reviews and listings across various categories. The platform also features photos, business hours, and contact information, making it a valuable resource for both consumers and business owners looking to improve their visibility.
