What B2B paid social actually is
Most B2B paid social is run as direct response: a cold audience, a demo ask, a cost per lead in a spreadsheet. It is the most reliable way to conclude that paid social does not work for B2B.
Paid social in B2B is a demand creation channel. Its job is to reach the right accounts before they are looking, build a retargeting pool worth capturing against, and make the branded search happen later. Judged on last-click cost per lead it will always lose to search, because search is harvesting demand that paid social created.
LinkedIn: the targeting no other social channel has
LinkedIn is the only social platform where you can target a named account list by job title, seniority, function and company size, and run content against those people repeatedly. That is the whole reason it anchors a B2B paid social programme despite the CPM.
What we run on it: thought leader ads as the demand engine, document and video ads for the account list, retargeting segmented by engagement depth, and conversation ads at the bottom where the ask lives. The benchmark set behind those choices is published in Kiin Labs, built on 1,000+ connected advertiser accounts and $58.1M of spend.
Meta: warm frequency at a tenth of the CPM
Meta has no reliable B2B targeting, so cold Meta for B2B wastes money. What it does have is the cheapest impression available against an audience someone else has already qualified.
So Meta is a middle-of-funnel channel here: custom audiences built from LinkedIn engagement exports, website visitors and CRM lists, plus lookalikes off those lists. The person who liked a thought leader ad on Tuesday sees the case study on Instagram on Thursday, at a fraction of what the same impression costs on LinkedIn. Video built for LinkedIn gets a second life.
How the two connect
- One account list runs through both. LinkedIn identifies and engages; Meta reminds.
- Audience passing from LinkedIn engagement and site traffic into Meta custom audiences and lookalikes, refreshed continuously rather than exported once a quarter.
- Shared creative, cut for each placement.
- One report. Split into two cost-per-lead columns, Meta always looks cheaper and the LinkedIn budget gets cut — which removes the qualification that made Meta work.
Reddit, where the buyer is technical
If the ICP is developers, security engineers, data teams or infrastructure buyers, they are in specific subreddits and are not on LinkedIn every day. Reddit’s community and interest targeting reaches them at low cost with the relevance those audiences demand. It is a secondary channel for a general B2B SaaS audience, and we include it only where the ICP is genuinely there.
How it is measured
- Landing page clicks, not clicks. LinkedIn’s click field counts likes, comments and profile views; on a thought leader ad it overstates traffic several times over.
- Form submissions, not form opens. Only a submission is a lead.
- Cost per landing page click and cost per lead by channel, side by side, so each channel’s role is visible in its own economics.
- Penetration and frequency on the target list across channels combined.
- Influenced pipeline and revenue by account where a CRM is connected, plus a self-reported attribution field on the booking form.
Pricing
$2,500 to $9,500 a month, published, no media mark-up and no long lock-in. Below roughly $5,000 a month in media, run one layer and make it capture. Between $5,000 and $15,000, LinkedIn plus Meta works properly. Above that, Reddit or LinkedIn CTV earn a place. Full detail on the paid media page.
Frequently asked questions
What is a B2B paid social agency?
An agency that runs the social side of a B2B paid programme — LinkedIn first, with Meta and Reddit as supporting channels — as demand creation and warm frequency rather than as a direct-response lead source. The distinction matters because paid social in B2B is mostly not where the conversion happens; it is where the demand that converts later gets created.
Should B2B companies run Meta ads?
Yes, but almost never cold. Meta has no reliable job title or company targeting for B2B, so cold Meta wastes money. Against an audience LinkedIn has already qualified — engagement exports, site visitors, CRM lists and lookalikes built off them — Meta is the cheapest frequency available, at a fraction of LinkedIn’s CPM.
How do LinkedIn and Meta work together for B2B?
LinkedIn does the targeting Meta cannot, then the people who engage become Meta custom audiences and lookalikes. LinkedIn creates and qualifies; Meta reminds, cheaply. Creative crosses over, and both are reported as one pipeline number so the budget does not drift to whichever column shows the lower cost per lead.
What does B2B paid social cost?
Kiin publishes its fees: $2,500 to $9,500 a month, no media mark-up. On media, below about $5,000 a month run one layer and make it capture. Between $5,000 and $15,000 LinkedIn plus Meta works properly. Above that, add Reddit or CTV.
How is paid social measured for pipeline?
Landing page clicks rather than LinkedIn’s default click field, which counts likes and profile views. Form submissions rather than form opens. Influenced pipeline by account in the CRM, plus a self-reported “how did you hear about us?” field, because last-click will credit the final branded search and erase the paid social that caused it.
Is LinkedIn or Meta better for B2B lead generation?
Neither alone. LinkedIn is dearest per click and cheapest per qualified lead; Meta is the reverse. Judged separately Meta wins on cost per lead and LinkedIn wins on quality, which is why they should be judged together on pipeline.
