Measuring your marketing department's efficiency is one of the main challenges facing all companies today.  Marketing reports require gathering data from website performance suites like Google Analytics, your sales software, and your accounting systems to understand the impact of marketing spend.

By understanding the source of your leads and opportunities, and the resulting wins, you can understand how much each lead and opportunity costs, and the ultimate cost of acquiring new customers through marketing channels.  Use this to make decisions about where to focus new ad spend, and what your most efficient blog postings are.
