Google provides yet another set of valuable educational resources at its Conversion University. On this site (marketed mostly to Google Analytics users), you will find loads of articles about creating a website that converts visitors into customers and helps retain your existing customers.
My favorite article found here was “Monetizing Non-Ecommerce Sites.” No, its not yet another article about how you can Get Rich with Adsense–it is an editorial on how you can measure the value of a non-Ecommerce site, such as a website that promotes a service-oriented business. Not only will the ideas presented help the average business-owner understand the important connection between their website and sales, but it also emphasizes the importance of tracking for determining your ROI (Return on Investment).
If you need a website that includes more conversion techniques, YNot Web can help. We also provide our own article section on Conversions, for those who want to investigate and test out ideas on their own.
