LinkedIn ads vs Facebook ads for B2B is a real trade-off, not a slam dunk either way. LinkedIn gives you the sharpest professional targeting anywhere, job title, company, industry, seniority, at a premium price. Facebook gives you much cheaper reach with fuzzier aim. If you sell to other businesses, the right pick depends on your deal size and how precisely you need to hit a specific decision-maker.
LinkedIn's unbeatable edge: targeting
Nowhere else can you say "show this only to HR directors at companies with 200 to 1,000 employees in manufacturing." That precision is LinkedIn's whole value. For B2B, where the person who signs matters enormously, that's powerful. You're not spraying and praying; you're reaching the exact buyer.
The catch is cost. LinkedIn clicks routinely run $6 to $12+, sometimes far more. That's the price of that precision.
Facebook's edge: cheap reach, decent targeting
Facebook can't target job titles as reliably (people don't keep their profiles work-accurate), but it reaches an enormous audience cheaply, and business owners are on Facebook too, just in personal mode. For B2B aimed at small-business owners rather than corporate departments, Facebook's cheaper clicks can win, because those owners are often just people running a company, reachable by interest and behavior.
Deal size decides a lot
- Big deals ($5,000+, long sales cycles, corporate buyers): LinkedIn's expensive clicks are justified because one client covers a lot of ad spend, and precision matters.
- Smaller deals or SMB owners as buyers: Facebook's cheap reach often wins on cost per lead, because you can afford to reach more people to find the few who fit.
Intent and mindset
Neither platform has search intent; both interrupt people. But LinkedIn interrupts them in "work brain," which is a real advantage for B2B, while Facebook interrupts them mid-vacation-photos. For messages that need a professional headspace, LinkedIn's context helps even beyond the targeting.
Creative differences
LinkedIn wants professional, value-first content, guides, case studies, clear ROI language, and a price signal to pre-qualify. Facebook tolerates more casual, benefit-driven, even entertaining creative. Reusing the same ad on both usually underperforms; match the tone to the room.
The honest recommendation
If your B2B buyer is a corporate decision-maker and your deals are large, lead with LinkedIn and accept the premium; the precision pays off. If you sell to small-business owners or your deals are modest, test Facebook first for cheaper leads, then layer LinkedIn for the accounts worth the extra cost. Many B2B businesses run both: LinkedIn for precision on high-value targets, Facebook for cheap volume.
Either way, send clicks to a dedicated landing page with a short form, not your homepage, and make sure that page actually converts; a free SEO & AI score is a quick check. Judge both on cost per qualified lead and closed deals, never on clicks.
Running two B2B funnels with different creative and different targeting is a genuine time commitment, which is why plenty of owners hand it to how Arbor runs your ads instead. For more channel-by-channel breakdowns, our growth guides keep it jargon-free.
