You set your Meta targeting to decision-makers at large businesses. Meta serves it. And the leads come back as solo founders and side-hustlers. The audience just isn't accurate, and no amount of tightening fixes it. Here's why, and what Meta is genuinely great at instead.
Why the interest audience leaks
On Google, a company's size is a fact, inferred from real data. On Meta, "company size" and "job title" come from what a person typed into their profile and what a page selected about itself: small, medium, or large business. Self-declared, rarely updated, often aspirational. Meta has also steadily narrowed its detailed-targeting options. So "target large enterprise" quietly resolves to whoever claimed to be one.
So what is it for?
Self-declared data is bad at precision, but it's fine at scale. That points Meta at three B2B jobs it does genuinely well, none of which asks the targeting to name the exact buyer.
Cheap reach. When the goal is broad awareness in front of a roughly-right audience, Meta's low CPMs are a gift. Stop asking it to pinpoint the enterprise decision-maker and let broad targeting plus strong creative do the sorting.
A creative testing ground. Meta impressions cost a fraction of LinkedIn's. Test your hooks, angles, and offers here cheaply, then take the winners to the pricier channels where your precise buyers actually sit.
Retargeting the warm. The one Meta play that is both accurate and cheap: re-engaging people who already visited your site, tracked by the Meta Pixel. It runs on what people did, not what they claimed, which is exactly where self-declared targeting falls down. It's the highest-leverage thing you can run on Meta for B2B, and it earns its own piece: why Meta is a retargeting channel first.
The right split
Use Google, LinkedIn, and your own uploaded lists to target cold buyers precisely, where the data is real. Use Meta for what self-declared data still does well: cheap reach, creative testing, and above all retargeting the people who already know you. It's the same logic as the three-campaign structure: match the channel to the audience temperature. Forcing Meta to do cold, precise B2B prospecting is asking the retargeting channel to do the prospecting channel's job, then blaming Meta when it can't.
The takeaways
- Meta's B2B firmographic targeting is self-declared, so "target enterprise" leaks to small businesses.
- Google infers company size from real data; Meta relies on what users and pages claimed.
- So use Meta for what self-declared data can do: cheap reach, creative testing, and retargeting.
- Target cold buyers precisely on Google, LinkedIn, and your own lists, not Meta interest audiences.
