Start at your planned 'revenue event' and work your way backwards to your expected traffic volumes. For example, if you have a plan to build a site with users and content, and your revenue plan is to sell T-shirts; - What percentage of checkout pages will be completed? - What percentage of tshirt page visitors will click the 'buy now' button? - What percentage of site visitors will click your promo to view the tshirt page? - How often will your users visit your site? - How many users will you have? Selling Tshirts isn't the best revenue model, but you can follow these steps to build a model for anything.
