My first question is asking about your competitors. If I want a company to provide the service you offer, can I find an established one with a quick search on Google? Do you rank well on search engines?

If I'm a customer then I'm going to look for the best product to provide the service, some people will base it on cost depending on the service.

Keep in touch with your potential customers. Reach out and say that your site is new and you'd like to know what they think and maybe even be as bold as to ask why they did or didn't purchase from you and if they purchased from a competitor.
