I'm encouraging every Provo Labs portfolio company to set up a shareable Google spreadsheet to keep track of daily web statistics. One of the keys to success in an online company is to look at very simple web stats every day to find opportunities and problems. For example, someone needs to look every day at the top referrers to your web site and the top search terms that are bringing you visitors. Every domain that sends you traffic becomes an important part of your company's ecosystem. These partners need to be watched, tended, encouraged, and rewarded.
