YouTube is changing how they're counting views starting August 24. How this affects you:
Previously a view was counted as soon as it hit ~30 seconds on long form
So now it might look like your views are increasing but likely your amount of engaged views will be the same. (which will still be a metric you can check)
What to do? Nothing. I mean it's coming, to get ready for it you should, keep uploading consistent quality content, it's literally not going to change how well a video performs, just the measurement of it.
If your videos sucked before this, your videos will still suck after this, the view count will just be inflated
and your drop off rates and average view durations are likely going to look a lot worse. though it's unclear if YT plans to use engaged views or total views to determine AVD as of yet
Hope this was helpful
