Google My Business is a free tool provided by Google that allows business owners to manage their online presence across Google's search engine and maps. By creating a Google My Business listing, you can add information about your business, such as your business name, address, phone number, website, business hours, and photos. 

Having a Google My Business listing is crucial for local businesses, as it helps them to appear on Google's search results when someone searches for products or services related to their business. By optimizing your listing, you can also increase your visibility on Google maps and attract more customers to your physical location.
