Well I found online that X pays about $8.50 per 1 million impressions, which is about $0.0085 or 0.85¢ per 1000 impressions. 10 sats ≈ 1¢.

We don’t have impression data on Nostr so it’s hard to make a direct comparison, but I definitely think I am making significantly more than 10 sats per 1000 impressions (I doubt I’ve ever reached 1000 impressions on a post). I’ve had posts get 10,000 sats, if I had to guess, maybe 100 impressions.
