I run a small workshop in Barcelona making handmade leather wallets and bags. I've been trying to promote my products on Instagram for about a month using boosted posts and the ad manager. I've spent a total of 450 euros over the course of the month, but I still can't figure out what I'm actually paying for or how this system works behind the scenes.
Sometimes a single click costs 0.20 euros, and other times it spikes to 1.10 euros for the exact same audience. The dashboard shows terms like CPM, reach, and amount spent, but I just can't wrap my head around the logic. Am I not just directly renting ad space, why does the price keep jumping around?
What exactly determines the outcome of the bidding and auction system? How can I stop burning through money with a small budget when I'm targeting the same audience as big brands?
