When you’re trying to sell your service to clients, one of the key factors they will look for is what results you have produced in the past.
Case studies, statistics and testimonials are what are going to convince your potential clients that you have the experience to be trusted.
However, it’s not the client’s job to understand all of this for themselves.
It is your responsibility to make evidence of your results easy to find. You also need to iterate about previous successes when a client reaches out to you. You can also include these when you send through a proposal.
Remember that your potential client will also be talking to other providers and just because you showed them your previous successes once, doesn’t mean they will remember you.
