Contractors often launch new product lines on a hope and a prayer. Instead, use a one page site to develop a list of prospects while they tell you exactly how they want you to sell to them!
Your website needs keywords, and each page of your website should rank for something specific inside your organization. But don’t over do it on keywords.
Email is NOT dead. In fact, it is the last place on Earth where you can have a private, one-on-one conversation with someone who has ASKED you to contact them. If you are not using this tool to market your contracting business, then you are screwing yourself!
