While I don't think DoorDash cares too much about the advertising revenue, per se, I think what's going on here is roughly this: - You search for a specific BBQ restaurant on Google. - You see an advertisement for that restaurant! But it's actually DoorDash. - You click on that ad, and DoorDash initiates a location-based search for BBQ restaurants, putting their preferred partners at the top of the result list. DoorDash is happy if you order from any restaurant through them, but they're even happier if you order from a restaurant that they get more money from.
