Hi there- I've noticed that Adobe Stock requires the top keywords to be ranked or at least put at the top of the list. I guess this helps them assign weights to each keywords to improve the search relevancy. 

Do you know if Shutterstock assigns weights to keywords ? It does not seem to be a requirement to upload. But maybe they generate that ranking in order to determine which weights to give to keywords.

Is it in my interest to rank the keywords when submitting to Shutterstock ?

Thanks a lot
