Understand your data, better and faster

How do you remember all the campaigns and improvements you made that affected ROI?


When something is occurring, the chronology is clear: it's happening now. But "Now" fades with the passing days, weeks, and months. How can you begin to measure the impact of any event on a website or mobile behavior if you can't remember when it happened? 🧐 

It's time to add the missing pieces to the puzzle! If there is one piece of data you want to see at a glance every time you log in to your analytics, are essential annotations.
