How can I evaluate the result of work if I do not understand the design?

We always do the same initial actions. And one of them is the inspection of competitors. More often than not, we understand that the design was done by graduates of art schools, because the result is ridiculous.

Look at them, track changes, and you will understand that our work is what they pay for.

You also have the opportunity to track sales growth after you install a new design on your website. Or start giving away your business cards, and they will call you. Or send a presentation to 10 potential customers, and get 5/10 responses.
