If you have no visibility in how your users are using your website or mobile app, you will have no idea of how to make smart decisions in your business. With proper planning and clear objectives and strategies, you can gain powerful insight into what users demand. Having an clear understanding of the user allows you to position your marketing messages, design, etc. to drive the outcome you want. If it's to drive collection of emails and data, the fewest clicks to make a decision and buy or simply to drive more traffic and consistent recurring visits or app usage, Google Analytics can help you figure out what you need to do.
