The document discusses how a company's website can be their best sales tool by focusing on three key things: having a clear message, web presence, and ability to track results. It emphasizes that a website needs to understand the customer's buying process and priorities in order to provide the right information at the right time. Specific tactics discussed include defining the customer persona, value proposition, mapping the buying journey to the website structure and content, and using analytics to continually improve. An example case study of a commercial cleaning company is provided to demonstrate how to apply these concepts.
