Meta ads for B2B: what Facebook and Instagram actually deliver

Most B2B teams treat Meta as a consumer channel and put the budget on LinkedIn. In 2025, across 153 B2B advertisers and $57.6M of measured spend, a Facebook lead cost $145 and an Instagram lead $138, against $202 on LinkedIn. This page is what that data says about running Meta ads for B2B: whether they work, what they cost, which audience and format to run, and where the numbers stop.

Do Facebook ads work for B2B?

Yes, measurably. In 2025, 71 B2B advertisers paid $145 per lead on Facebook and 49 paid $138 on Instagram, against $202 on LinkedIn, across $57.6M of spend from 153 advertisers. What Meta does not do as well is convert a click: 2.6% of Facebook clicks became leads against 5.9% on LinkedIn.

The objection to Meta for B2B is usually about targeting: Facebook infers who is a buyer from interests and behaviour, LinkedIn knows from the profile. That is true, and it shows up exactly where you would expect, in the share of clicks that turn into a form fill. It does not show up in the price of the lead, because a Facebook click costs a fifth of a LinkedIn click. The two effects roughly cancel, and Meta comes out cheaper per lead. Whether it comes out cheaper per customer is a different question, answered further down, and the honest answer is that for most of Meta this dataset cannot say.

How much do B2B Facebook and Instagram ads cost?

In 2025 a B2B lead cost $145 on Facebook and $138 on Instagram, spend-weighted across 71 and 49 advertisers. Facebook clicks cost $1.95 at a $15.50 CPM; Instagram clicks cost $2.82 at an $18.25 CPM. The Facebook advertiser in the middle of the market paid $179 per lead.

B2B paid social benchmarks by channel, 2025, all campaign goals. n = advertisers in that cut.

Google Ads is a search channel and its CTR and CPM are not comparable with social; it is here because it is the other place the same budget goes.

Is Facebook or Instagram better for B2B ads?

Instagram bought the cheaper lead in 2025, $138 against $145, and converted more of its clicks, 4.0% against 2.6%. Facebook had the cheaper click, $1.95 against $2.82, and the lower CPM. On cold audiences alone Instagram cost $153 a lead across 37 advertisers and Facebook $166 across 59.

Read the advertiser counts before the prices. Instagram has 49 advertisers behind its headline number and 37 behind the cold cut, Facebook 71 and 59. Both clear the publication threshold, and the Instagram figure was the cheapest B2B lead in the whole dataset, but it is the thinner of the two. The practical reading is not "move to Instagram"; it is that a B2B team already buying Facebook placements has no data-based reason to exclude Instagram from them, and a reason to test it on its own.

Should B2B Meta ads prospect or retarget?

Retarget first. Facebook retargeting cost $120 per lead in 2025 against $166 for prospecting. Meta is the only channel in the dataset where that holds: on LinkedIn, retargeting cost $234 per lead against $194 for prospecting.

Cost per lead by audience type and channel, 2025 lead-generation campaigns.

This is the finding that should change how a B2B team structures Meta. The agency consensus, that Meta is a retargeting and lookalike engine rather than a cold-prospecting channel, is correct on the cost side: the warm audience is where the cheap lead is. The surprise is LinkedIn, where the retargeting pool costs more to convert than a cold prospect, most likely because LinkedIn's retargeting audiences are small, expensive to reach and already saturated with the advertiser's own creative. If you run both channels, the efficient split is the one most teams have backwards: cold on LinkedIn, warm on Meta. The paid social retargeting playbook covers the audience build.

Which Meta ad format produces the cheapest B2B leads?

Static image. Facebook image ads cost $136 per lead in 2025 against $225 for video, a 40% gap. The same pattern held on LinkedIn, where document ads cost $142, image $200 and video $265.

Several 2026 guides to Meta for B2B recommend leading with Reels and carousel on the strength of click-through rate. That may be true of clicks. On cost per lead, across the advertisers in this dataset, the plainest format won by a wide margin on both social channels, and video was the most expensive way to buy a lead on Facebook. Video earns its place when the job is to explain something a static frame cannot, not as the default lead-generation unit.

How do Meta ads compare with LinkedIn for B2B?

Per click and per lead, Meta is cheaper: $1.95 against $9.39 a click, $145 against $202 a lead. Per customer, only LinkedIn can be priced: $58,572, on 10.2x of sourced pipeline per dollar, against $31,939 and 7.97x across every channel.

So the comparison most teams want, "is a Meta customer cheaper than a LinkedIn customer", is one this dataset declines to answer, and any page that answers it for you from a smaller sample is worth reading carefully. What can be said: LinkedIn's premium per click bought it the most sourced pipeline per dollar of any channel, and Meta's discount per lead has not been shown to buy a worse customer. The older comparison of Facebook against LinkedIn for B2B brands reached the same conclusion from a different direction.

How should a B2B team run Meta ads?

Start with the retargeting pool, run image creative to cold audiences you built yourself, and measure to the customer rather than the lead. Each of those is a number in this dataset, not a preference.

1. Retargeting before prospecting. $120 against $166 a lead. Build the warm audience from site visitors and CRM lists first, and let prospecting scale only once the retargeting pool is being fully served.
2. Image first, video for the jobs only video can do. $136 against $225. Test video against image on the same audience before giving it budget.
3. Build the audience yourself. Across all channels, audiences the advertiser built from firmographic and CRM data cost $208 a lead against $176 for the platform's own targeting. Judge them on pipeline per dollar, not on cost per lead.
4. Trace revenue to the ad or stop calling it performance. Of 132 B2B advertisers running lead-generation campaigns in 2025, 42 had no CRM opportunity signal at all. Meta's cheap lead is only an argument if you can see what it became. Send opportunity and closed-won events back to the platform so it optimises toward the thing you sell.
5. Compare like with like. These are spend-weighted 2025 figures. If your Facebook cost per lead is above $145, compare against the middle of the market at $179 before deciding anything; audience, offer and format move the number more than the channel does.

How were these numbers calculated?

From 153 B2B advertisers running paid media through Metadata in calendar 2025 and $57.6M of spend. Every figure is a spend-weighted aggregate, and every cut is gated on at least five advertisers, $50,000 of spend and no single advertiser above half of it.

Pipeline figures use the subset of lead-generation campaigns with CRM opportunity attribution and a stricter bar: at least eight advertisers, three closed-won opportunities and no advertiser above 40% of wins.

Cuts that fail those thresholds are left out. The full methodology, is public, and the anonymised dataset is available under CC BY 4.0.

Benchmark context: every figure on this page is drawn from Metadata's 2026 B2B Paid Media Benchmark. The channel reference table with CTR, CPC, CPM and cost per lead is on B2B advertising benchmarks; the LinkedIn side of this comparison, with the full cost-per-lead distribution, is on LinkedIn ads cost for B2B.
