Entrepreneurs

I own a business that sells directly to customers we find through local Facebook and Google advertising. Our profit model is just ok - the business pays its own bills but I don't feel that it's been worth my energy yet. About 2 years ago I opened a retail shop in the city, decorated it nicely, but in a poorly located building that doesn't have much walk-in traffic and very little parking. I'm considering relocating to an area that would be much better located for parking and walk-by traffic. Of course the price is higher, about twice as much. I'm looking for advice about how to decide if this is a wise move. I don't understand which metrics are important for retail as I try to spreadsheet this idea, and my background is in e-commerce and services businesses. I'd like to be able to make some educated assumptions about whether our sales will increase and by how much.
