I think the idea of the searcher getting a portion of the ad revenue is great, but I don't think this can translate to 100 sat per search. It should get built into some percentage algorithm IMO.
They are selling specific search terms, or words, for the right to get the revenue from that search. Maybe this will work out to a nice system in the free market but for now it seems IPOish and I will assume it is a scam until proven otherwise.
If they weren't taking peoples money then I would think "wow this is a great idea", which it is. But from my experience you can't trust anything like this in the crypto space so guilty until proven innocent.
Best of luck though, I hope it's not a scam, very cool idea..
Edit: combine posts....
Yes, only the first 40 searches are paid, then it's free... 100 satoshis per search or 0.00000100 bitcoins/search.
40 per day? week? month? or ever?
If ever then it's basically pointless as you can only make a laughable 4,000 satoshis..
Mine says I'm paid for 13 searches and have like 36 pending paid searches BTW... Not 40.
