I wasn't planning to think about marketing formats as an interface design problem, but the parallel got hard to ignore once I looked into how Meta structures its ad products.
Meta Ads isn't one API surface, so to speak — it's five distinct formats: Image, Video, Carousel, Collection, and Lead Ads. Each one is optimized for a different job, the same way you'd choose a different data structure depending on whether you need fast lookups or ordered iteration.
Here's roughly how they map to different "jobs to be done":
Image Ads: cheapest, fastest to ship, suited to a single simple message. Good for a quick test, weak at anything requiring nuance.
Video Ads: higher production cost, but tends to outperform static images on cost per result, partly because the platform's ranking favors video placements.
Carousel Ads: a sequence of 2-10 independent units (cards), each needs to work standalone since the platform can reorder them for different viewers — a subtle but important constraint a lot of people miss.
Collection Ads: essentially an embedded storefront, only worth the setup cost once you have a real catalog (6+ items).
Lead Ads: removes an entire step (the landing page) by pre-filling a form in-app — a straightforward friction-reduction move.
What struck me is how much this mirrors decisions I've made in software: pick the wrong abstraction for the problem, and no amount of "more resources" (budget, in this case) fixes it. A well-funded campaign in the wrong format underperforms a cheap campaign in the right one, structurally.
I came across this framing while reading through material from Impact Digital Marketing Institute, which teaches format selection as a pre-budget decision rather than a creative afterthought — which tracks with how I'd think about picking a database before optimizing queries.
If you've made a career switch into or out of marketing-adjacent work, I'm curious whether you noticed similar "wrong abstraction" patterns in other non-technical domains you picked up.
