It's important to write a description about your business/location. This gives more substance to a local search result, it makes sure the location will be found better and adds to the overall online search experience.
First describe your business in max 10 keywords. These keywords help to increase your findability when related queries are being entered.
Platforms either accept a short or long description. The short description is limited to a maximum of 200 characters. The long description is limited to 1000 characters. Please take the time to write a compelling description.
TIP: Try doing this backwards, start with your long description, then create the short description out of the long description, and ultimately bring the short description back in 10 words.
IMPORTANT: With Google there's an exception. Google will take a long description that has less than 750 characters into consideration first. If the long description has more than 750 characters, then Google will display the short description. As an example if the long description has 743 characters, then the long description will be displayed on the public GMB page.
