Footage: Fifty Keywords Hierarchy

[Amanasleep]

Hi everybody,

My question is about this note on official Adobe Stock metadata recommendation post:

Note:

*The first 10 keywords you list are given extra priority in search. If however you maximize your keyword quantity at 50, the weight of each keywords is distributed evenly in search.

I'm talking about footage now. I usually write all 50 keywords, does this mean that there is no point for me to choose and prioritize top 10 or hierarchy still matters?

Thanks!
