Oh right... didn't notice that the URL was different than the one you messaged me.
They just can't rank for position zero.
Right. In my screenshot and the ones in your article, it's the snippets where the competitors win. The affiliates who have done this well must be making a killing. I have not checked recently, but Bluehost always paid out around $100 per signup.
[update: currently $65 which is still a nice payout - someone is doing very well with that featured snippet until Bluehost gets their act together]
