There are many metrics that teach you about user behavior. Here are some popular ones.

1. Time on Page: Also called dwell time, this is the amount of time visitors are spending on a particular webpage. If they are spending very little time on a long-format piece, you know that they are not reading it. But if they spend just a few seconds on an ‘about me’ page, that’s not so bad. So, focus on content and the corresponding time. 

2. Pages per Visit: This tells you how many pages a visitor has gone through which tells you how engaging the content has been. So, you can make changes to the content accordingly. Or leave it as is. 

3. Bounce Rate: This is the rate of visitors leaving a page without browsing it. It tells you whether visitors are finding the quality of content engaging or not. But remember that it does not tell you anything about their experience. Sometimes, when websites are redesigned and madebetter, the bounce rate increases before it goes down because people are not used to the new layout. 

So, be sure to read the data but also use your own judgment to understand what the numbers are saying.
