You can add a wealth of information to your Google business listing to make it more comprehensive and helpful for potential customers. This includes your business name, location, contact details (phone number and email), business hours, and website link. You can also add photos to give people a visual idea of your business, products, or services. Additionally, you can share updates and posts, respond to customer reviews, and even add special attributes like if your business is women-led or offers outdoor seating. Remember, the more complete and up-to-date your information, the better it is for your online presence.
