Who posted it: How popular is the person who posted it?

A Reel on Figo Pet's Instagram channel that shows someone sitting at their desk with their computer in the background and text on the screen that reads "some of the best pet names I've seen working in pet insurance, part 2"
Here are the top signals the Instagram Reels algorithm uses to determine which Reels to show users:

User engagement: What Reels has someone line data engaged with recently? (I.e.: Likes, comments, shares.)
Interaction history: Have you ever interacted with the person who posted the Reel before? Reels are meant to reach new people, but past interactions suggest interest.
The content: What audio or music does it use? How’s the quality?
What to avoid in your Reels
Just as you can win points with the algorithm, you can lose points, too. Avoid these common mistakes.

Low-resolution Reels (blurry or low-res)
Watermarked Reels (including the TikTok logo)
Reels with no audio
Too much text
Political Reels

As Instagram put it on their blog, “Feed and Stories are places where people want to see content from their friends, family and those they are closest to.”
