LinkedIn ads vs Facebook ads for B2B: what the numbers say

LinkedIn ads vs Facebook ads for B2B: the short answer

For most B2B companies selling into thousands of businesses, Facebook and Instagram produce cheaper leads, while LinkedIn wins when you sell to a small, named list of accounts and the deal is big enough to carry its higher costs.

That's the honest answer. Not the one either platform's sales team gives you.

Here's what the 2025 data says:

• Cost per click: LinkedIn $9.39 vs Facebook $1.95, per Metadata's 2026 B2B benchmark of 153 advertisers (2025 data).
• Cost per lead: LinkedIn $202 vs Facebook $145 in the same report.
• Return on ad spend: LinkedIn 121% vs Meta 51%, per Dreamdata's 2026 LinkedIn Ads Benchmarks Report.

Wait. Facebook is cheaper per lead, but LinkedIn returns more revenue?

Both can be true. And that gap is the whole story of this page.

What you do AFTER the click decides more than which logo is on the ad.

LinkedIn ads cost vs Facebook ads cost: CPC, CPM and CPL benchmarks

LinkedIn costs roughly four to five times more per click and per thousand impressions than Facebook for B2B advertisers, but its clicks turn into leads at more than twice the rate.

These figures come from Metadata's 2026 B2B advertising benchmarks: 153 B2B advertisers, $57.6M of spend and 211,000 leads across calendar year 2025.

Three things jump out.

First, Facebook and Instagram are close cousins. Same Meta system. Instagram actually posted the lowest cost per lead.

Second, the LinkedIn sample is nearly double the Facebook one. B2B marketers still default to LinkedIn. That hints at fewer B2B competitors bidding for the same buyers on Meta.

Third, the CPL gap is smaller than the CPC gap. LinkedIn clicks are expensive, but they convert better. A good chunk of that is LinkedIn's pre-filled Lead Gen Forms: Metadata puts LinkedIn lead forms at $193 per lead against $346 for landing pages.

One more catch. Metadata's $202 is spend-weighted. It says three out of four LinkedIn advertisers paid more, and the middle of the market paid $376. Budget for the middle, not the headline.

Cost per lead is the wrong scoreboard for both

Cost per lead hides the only thing that matters, which is how many of those leads become held sales calls and closed deals.

Dreamdata's 2026 report covers more than 3.5 million B2B customer journeys from its own customer base. LinkedIn came out at 121%. Google Search at 67%. Meta at 51%. Per PPC Land's summary of the report, Meta was up from 29% a year earlier, and ROAS is measured on closed-won deals over 12 months with Dreamdata's data-driven attribution model.

Metadata's CRM-connected data points the same way: LinkedIn sourced about $10.20 of pipeline per $1, against $7.97 across all channels.

Before you move your whole budget, two caveats:

• Attribution is a model. Per PPC Land's summary, Dreamdata puts the average B2B journey at 272 days, up from 211. Over that long, credit gets spread across many touches. Different models give different winners.
• The average hides the funnel. Most Meta B2B campaigns send traffic to lead forms or homepages. Average Meta ROAS reflects that.

Watch what happens when you change the funnel instead of the platform. Same $10,000 of spend. The CPLs are Metadata's. The other inputs are illustrative, not benchmarks.

The platform swap saved about 30%. The funnel swap saved about 70%.

That's why we judge every channel on cost per held call. Work yours out with the cost per held call guide.

LinkedIn ads targeting vs Facebook ads targeting for B2B

LinkedIn targets B2B buyers by the job title, seniority, company and company size on their professional profile, while Facebook reaches the same people through broad targeting and lets the ad itself filter for the buyer.

LinkedIn's edge is real. You can say "VP of Finance, 200 to 1,000 employees, software companies, US" and get exactly that.

LinkedIn's Matched Audiences also let you target key companies and upload your own contact lists. For account-based marketing into a few hundred named accounts, nothing else comes close.

Meta can't do that reliably. Its work data depends on what people type into their profiles, and plenty never fill it in.

So on Meta, the creative IS the targeting:

• Call out the role in the first line. "Agency owners stuck at the same revenue..."
• Name a pain only your buyer feels.
• Let the algorithm find who responds, then qualify them in the quiz.

Sounds loose. It works because Meta's reach is enormous and its clicks are cheap. You can afford to test ten angles on Meta for the cost of two on LinkedIn.

The full Meta playbook is on our Facebook ads for B2B page.

LinkedIn ads vs Facebook ads: audience, formats, pros and cons

Facebook has far more people and cheaper, more flexible formats, while LinkedIn has fewer people but a professional profile on every one of them.

Per HawkSEM's comparison, Facebook has over 3 billion active users (citing Statista) and LinkedIn has under one billion (citing LinkedIn). Smaller pond. Better labels.

Metadata's comparison makes a point worth stealing: Facebook's delivery self-optimizes, pushing more of your budget to whichever people convert. That's exactly why the conversion event you feed it matters so much.

LinkedIn's edge is labels. Meta's edge is learning. Use each for what it does best.

Is LinkedIn or Facebook better for B2B? The decision matrix

Choose by market size, deal size and how you sell, because those three things decide whether LinkedIn's precision is worth its premium. The thresholds below are our rules of thumb, not platform rules.

Notice that "both" shows up a lot. The question isn't really LinkedIn OR Facebook.

It's which one carries the weight, and which one plays support.

LinkedIn Lead Gen Forms vs Facebook lead ads: the same trap

Native lead forms on both LinkedIn and Facebook lower your cost per lead and raise your no-show rate, because one tap with pre-filled details takes almost no intent.

That's partly why LinkedIn's click-to-lead rate looks so strong at 5.9% in Metadata's data. The form fills itself in.

Now look at what happens downstream. Focus Digital's 2026 review of published no-show data estimates calls booked from a paid search or paid social lead form at a 33% no-show rate. Calls booked through one-click instant booking at form fill: 8%.

Same buyer. Same ad budget. Four times the no-shows.

The fix works on either platform:

1. Send the click to a short qualifying quiz, not a native form.
2. Put the calendar inside the quiz, so the booking happens while they're interested.
3. Confirm by email and SMS instantly, then send a short VSL before the call.

Our quiz is 7 questions and takes about 30 seconds. It reads like a diagnosis, not a form. The build is in the quiz funnel blueprint, and the show-rate side is covered in sales call show rate.

LinkedIn ads minimum budget and how to test both fairly

Test LinkedIn and Facebook fairly by sending both to the same offer and the same funnel, then comparing cost per held, qualified call over at least a month.

Most "tests" are rigged by accident. LinkedIn gets the lead form. Facebook gets the homepage. Then someone declares a winner.

Do it properly:

1. Same offer. One cold traffic offer on both. See the irresistible offer.
2. Same landing path. Both go to the quiz with the calendar inside. Tag the source.
3. Enough budget to learn. LinkedIn's floor is $10 a day per campaign, with a $100 minimum lifetime budget for new campaigns, per its own budget guide. That floor buys almost nothing. At the $376 middle-market CPL, 20 leads is about $7,500. Size both platforms for real bookings, not five clicks.
4. Same scoreboard. Booked, held, qualified, closed. Track each by source in the CRM.
5. Same patience. Give both the same weeks. Judge on held calls, then revisit on closed deals.

Then compare one number: cost per held, qualified call. Clicks, CTR and CPL are inputs. Calls with real buyers are the output.

That's the scoreboard we run for every client. We've scaled 85+ SaaS and B2B brands. Our SaaS clients get 100+ booked sales calls a month.

How we use Meta, Google and LinkedIn together

We run Meta and Google as the engine for booked B2B calls and treat LinkedIn as a specialist tool for small, named account lists.

Here's why that split works for most B2B owners:

• Meta creates demand. It reaches buyers before they start searching, at a cost that allows real creative testing.
• Google captures demand. It catches the buyers searching right now. See Google Ads for B2B.
• LinkedIn targets accounts. When the list is small and the deal is big, its precision earns the premium.

All three feed one funnel: a 7-question quiz, the calendar inside it, CRM, email and SMS follow-up, and a VSL. Built and live in 14 days.

The offer: a B2B booking machine built to land 5-7 qualified sales calls on your calendar every single day, with held and qualified calls reported separately.
