Who it reachesThe widest audience of the four, with the deepest targeting and — more usefully — the deepest exclusion tools, so prospecting and follow-up stay apart.
What the creative must doStop a scroll and make one specific promise. Static images still beat video here more often than people expect, and lead forms remove the landing page from the equation entirely.
What you judge it onCost per booked job or order, read weekly. Enough volume passes through it that a week is usually long enough to mean something.
Who it reachesThe same Meta audience, in a room where people came to look rather than read. Planned in the same account as Facebook, so the two are bought once, not twice.
What the creative must doShow the work instead of describing it. Vertical, first frame doing the job, words on the screen because most of it is watched on mute.
What you judge it onCost per result, plus how long a creative lasts before frequency starts lifting it. Creative lifespan matters more here than anywhere else.
Who it reachesPeople by job title, seniority, function, company size and named account. It is the only one of the four where that data is the product rather than an inference.
What the creative must doOpen on the problem, in the language of the person who signs the order, and land somewhere a procurement lead can forward internally without explaining it.
What you judge it onQualified conversations and pipeline, over months. Judging it on cost per lead against Facebook will always make it look expensive, because it is buying a different thing.
Who it reachesPeople who are not looking for you at all, at the lowest cost of reaching a person of the four. Demand is created here, not caught.
What the creative must doEarn the first second. Shot rather than designed. Spark Ads run a real post — yours or a creator's — as the ad, which is why it rarely looks like one.
What you judge it onCost per result, and how many genuinely new concepts a month the account can absorb. An account that cannot make new creative cannot hold this platform.
