Both are "paid social," so they get lumped together. But for B2B they sit at opposite ends of a single tradeoff: how precisely you can pick the person, versus how little you pay to reach them.
LinkedIn: precision, at a premium
LinkedIn knows where people work, their job title, seniority, function, company size and industry, because users maintain it themselves. No other platform lets you say "heads of finance at 200–1,000-person SaaS companies" and actually hit them. For account-based and role-specific B2B, that's unmatched.
You pay for it. LinkedIn carries the highest cost per click of the major channels (commonly several times Meta's) and high CPMs, because inventory is limited and the targeting data is premium. The math only works when the deal is valuable enough that an expensive click can still return, high-ACV B2B, considered purchases, long sales cycles.
Meta: reach, for cents
Meta has enormous scale and the lowest cost per click anywhere. Your B2B buyers are on Instagram and Facebook too, as people. The limitation is that Meta's "B2B" targeting is inferred from behavior and self-declared interests, not verified employment, so it's noisier and leaks: you aim at enterprise and reach small business, you target "marketing managers" and catch marketing students. It's a vibe, not a fact.
That makes Meta excellent for cheap top-of-funnel reach, brand, and especially retargeting the people your other channels warmed up, and weaker for cold, precise role targeting where leakage wastes budget.
We see the cost of that guess constantly. B2B founders default to Meta because the clicks are cheap, then the leads come in noisy, students, the wrong company size, people who will never buy, because Meta is inferring who's B2B, not verifying it. The cheap click stops looking cheap once you count how many of those leads were the wrong person. That's usually the moment LinkedIn's premium starts to make sense: you pay more per click, but far more of the clicks are the person you meant.
Side by side
| Meta Ads | LinkedIn Ads | |
|---|---|---|
| Strength | Cheap reach at scale | Precise B2B targeting |
| Targeted by | Interests & behaviors (inferred) | Job title, company, seniority (declared) |
| B2B accuracy | Noisy, leaks | Exact |
| Cost per click | Lowest anywhere | Highest of the major channels |
| Cost per 1,000 views | Low | High |
| Audience size | Billions | Hundreds of millions, professional |
| Best for | D2C, top-of-funnel, retargeting | High-ACV B2B, specific roles, ABM |
Which to choose
Choose LinkedIn if your buyer is a specific role at a specific kind of company, the deal is worth thousands, and reaching the wrong person is pure waste. The premium click buys you zero leakage.
Choose Meta if you're D2C or your B2B offer is low-ticket, you need volume cheaply, or you're retargeting a warm audience. You'll get far more reach per dollar, and accept some targeting noise.
A common B2B combination: use LinkedIn to define and reach the precise accounts, and Meta to retarget those same people cheaply across their personal feeds once they've engaged, precision to find them, reach to stay in front of them. And know that even on Meta, B2B targeting is self-declared and leaky (more on that here).
The takeaways
- LinkedIn targets verified job title, company and seniority; Meta infers B2B from behavior and leaks.
- Meta is the cheapest reach anywhere; LinkedIn is the most expensive click of the major channels.
- LinkedIn's premium is worth it only when deal size justifies the click, high-ACV, considered B2B.
- A strong B2B combo: LinkedIn to reach the precise account, Meta to retarget those people for less.
