I heard this in the podcast. In your buyer requirements, place a question asking where people found you. Make it a must answer. So far, the insights are great. I know what keywords have been used to search for the service that lead to me. I can adjust my tags based on that. I also know my sales so far come from Fiverr searches or Google searches based on keywords that bring up my service on Fiverr. Helps me know how to advertise.
Pretty neat idea.
