What makes a product leaderboard actually useful?

I’ve been building SaaS Rank for the past 18 days and I’m trying to figure out what makes a leaderboard genuinely useful rather than just another product directory.

So far we have:

• 37+ products listed

• 2,235 visitors

• 11.7K views

• 738 clicks sent to listed products

• $400+ in revenue

The interesting part has been seeing that people are willing to pay for a better position, but I’m still figuring out what makes the leaderboard something they want to keep checking and competing on.

For people who have launched products before: what would make a leaderboard like this genuinely valuable to you?
