Full Sales Funnel Tracking

Spending a lot of time looking at lots of businesses marketing strategies I am always amazed at businesses that do not track the full sales funnel. It is not only good for complete data it also allows you to make complete full decisions on marketing budgets and spend. For instance, on an AdWords’ campaign with 1,000’s of keywords how will you know what CPC’s you should bid unless you have tracked and calculated you keywords EPC (Earnings Per Click).
