If you are using the Business Listings with your website, then you can put in a description within the settings that will be used for Google My Business. A good description can make your business appear more prominently and attract more potential customers to your website or your store location.
Google provides a set of guidelines that you’ll have to adhere to when writing your description. You can have a look at the guidelines here:
Read these guidelines carefully and keep them in mind when writing the draft of your business description. Furthermore, you should try to keep your description succinct and ensure that one or two important keywords related to your business are far in front in the description.
Reminder: Keywords are the terms you want your website to be found by in web searches, e.g. in Google search.
You should also make sure that there are no links in your description and that the formatting is normal, e.g. your text does not contain capital letters only. Use your own words to describe what makes your business unique and why customers should pay you a visit.
Finally, before putting in your description, read the guidelines by Google once again and reassure that your text adheres to the standards set by Google. This is especially important because your text will be reviewed by Google prior to the approval.
