To add tracking to your landing page, you need to first choose an analytics tool that's right for you. One of the best tools for this is Google Analytics as it's absolutely free, but there are other tools that you can use which can give you additional insight. Once you've chosen a tool and set up your account, you will need to insert a tracking code into the HTML of your landing page. That way, the tools can provide you with insightful landing page performance metrics.
