Customers are going to do their research online before hiring a local contractor. They look at your website, your past work, and your customer reviews. This is the zero moment of truth,
when a stranger decides if they're going to hire you or move on to one of your competitors. If you don't impress them at this point, you will lose that customer forever.
Company's who have a well-polished online presence are more attractive and come by new customers much easier.
