This document discusses how to measure the success of a website through web analytics. It recommends setting up separate accounting for the website and tracking key metrics like visits, conversion rate, and sales statistics. Conversion rate is very important but what counts as a conversion depends on the business - for a retailer it's sales numbers and values, for a lead generator it's requests for quotes. The document also discusses diagnosing issues with low conversion rates by examining the audience, website itself, business fundamentals, product selection, competition, expectations, and sales integration.
