You don’t always know when someone is impersonating your business, but if they succeed in scamming a customer, you definitely find out! Here are some resources and steps to take if you discover your business is being impersonated or has successfully scammed a shopper.
One tip that I don’t see mentioned is to regularly and routinely search for your business, store, product, your own name, etc online. If you find suspicious results, you can hopefully take action before a scam has been successful. Document the findings of your searches so that you can easily and reliably track any changes over time (hello, spreadsheet).
