The challenge

A hearing aid company wanted more people to see free hearing tests, in Mexico, Brazil, Peru, without a big media budget or a marketing team running it every day.

What they did

Ran 16 campaigns on ChatGPT and Push, split by offer and country.
Used Smart pricing: PPCmate set the price per impression automatically to win the right traffic.
Capped frequency on all campaigns so the same person didn't see the ad too often.
Blocked weak placements with a block list on 10 of 16 campaigns.
Kept spend on proven placements with an allow list on 8 of 16 campaigns.
Used day-parting on 11 of 16 campaigns to run only in the best hours.
Adjusted bids per traffic source with Source Bids on 9 of 16 campaigns.
