Install a tool like Nudge. Nudge enables you to get customer insights with ease, diving straight into how customers are engaging, what they’re paying attention to, where they’re coming from, on what devices. And then it makes analysts jobs easier by synthesizing the data into insights, so you can get from insight to action faster.
That’s the best place to start, capturing data on what you are doing, with analytics. Most will provide you some analysis out of the box, which can give you more insight. And then over time you develop your own reports and analysis that make the most sense for your objectives.
