Who are you selling to?
Learning about your customers is a vital stage in the marketing process. The more better your information and knowledge, the more effective you can be at selling. Use all the information available to understand customer's behavior, their demographics, and requirements. This information should guide your major business decisions and help you to write a marketing plan.
There are many online tools available for website analysis but of course it goes much deeper than how they browse. For instance if your customer base has a strong family bias, remember child care and schools have a massive impact on family life. Your customers will be experiencing this and its just one factor that may effect their purchasing descision. You can even install forms and customer surveys on your website to gather data directly from those interested in your company.
