"request count" is probably the number of times the link was accessed. Probably how many times the link was accessed by an application to put it in the feed. The term "unique views" is the number of real people who saw it. For example, I can open the link 10 times, which would be 10 requests and one unique view.

Amazing to think how the creators tools are going to develop on Nostr. Scheduling / analytics being 2x areas I can see massive improvements
