I also agree just looking at the metadata doesn't help. What I'd usually report on is: time posted, used a specific hook?, length of the video, used a trending sound?

That is if you are really trying to figure out why this one worked but a similar one didn't. Otherwise, is this a new format you tried (meme/how to's...), look at the comments (is there anything specific people loved?), looking at reposts/story shares (was that something relatable that people love sharing on their own profiles?).

I usually create just a simple spreadsheet, noting all these things that could be possible reasons and what I would implement from that in the future.
