If you are scrolling through social media and there is a big bright video that takes up most of the screen, chances are, you are going to watch it because of its size and the fact that it’s appealing and it’s taking up the majority of your screen.
On the other hand, if that same video was half the size and only took up a small portion of your screen and is hard to see, you might just keep scrolling because it wasn’t optimized to the placement that it was shown on.
Facebook and Instagram have algorithms that decide if your content is worth seeing or not.
