> The cost of pushing ads to people who already have mattresses is insignificant to capturing those that are about to buy them, statistically speaking.

This is called conversion rate and for some businesses it can be surprisingly tiny while still making that business completely viable.

I would hazard that rates in the mattress industry are almost preposterously low (<5%) but margins are so high that it doesn't matter in the slightest
