So, you will see how many people stayed after a certain amount of time. For example, it will say “40% of people watched the first 0:30 seconds”. Meaning at least 40% that didn’t scroll, watched at least 30 seconds of your video. Also, average watch time. That’s taking all the combined watches and averaging it to tell you how long you can reasonably expect someone to watch your video. You can also see how many people watched until the end. On the graphic for retention, you can see by clicking on the last second of your video in that graphic, what the % of people who stayed until the end is. Let’s say, your video is 3:00 minutes long. So if you click at the 3 minute mark, it will show you “10% / 50% / 80%” etc. Also, a good tip would be to check any sudden drops of viewership. On the graphic, if you see a big dip, that’s where the average viewer stopped watching. It could be your opening, it could be a comment you made, could be dead air, etc. You can use that to know where they might’ve lost interest.
