B2B paid social agency UK: LinkedIn vs Meta ads specialists

What to take away

LinkedIn Ads suits narrow targeting of named roles and companies, while Meta suits wider reach and creative volume.
Most UK B2B programmes need both platforms, but one should carry the primary lead-generation budget.
B2B specialists such as The B2B Marketing Lab, Digital 22 and Fifty Five and Five lead with LinkedIn Ads and account-based marketing.
Social-led shops such as The Social Shepherd and PPC Geeks often run Meta for demand capture and retargeting.
Compare fees on one identical scope, because a channel label hides most of the work.

Start with the buying group, not the platform

A B2B sale usually involves several people: an operations lead, a finance approver and a specialist user.

B2B buying group roles

Operations lead
Finance approver
Specialist user
Internal champion
Purchase blockers

Your target audience definition has to cover that group rather than one job title.

That single fact shapes the plan more than the platform choice does.

An audience built only from job titles will miss the internal champion who reads the research before anyone else.

It also misses the people who block the purchase.

LinkedIn Ads: what the fee buys

LinkedIn's self-serve advertising products target by job title, seniority, company size and uploaded company lists, which is why buyers treat the channel as the default for named-account lead generation.

LinkedIn Ads agency pricing models

Percentage of spend

How fee is set: Share of ad spend
Cost per qualified lead: Varies with spend
Best when: Spend scales

Flat retainer

How fee is set: Fixed monthly fee
Cost per qualified lead: Predictable
Best when: Scope is fixed

The B2B Marketing Lab, part of Iron Horse, is a UK B2B agency with HubSpot roots.

Digital 22 in Harrogate is a HubSpot Elite partner and runs LinkedIn Ads.

Fifty Five and Five in London focuses on Microsoft partners and LinkedIn Ads.

When the audience is narrow, argue about cost per qualified lead, not cost per click.

Agency pricing on this channel varies between percentage-of-spend and flat retainer models, and our guide to LinkedIn advertising agency pricing sets out how UK agencies present each one.

Uploaded company lists are an asset. Ask who builds them, who owns them, and what happens at contract end.

Meta ads: reach, creative volume and demand capture

Meta's self-serve ads tools cover Facebook, Instagram and Messenger placements, and they reward volume in both audience testing and creative.

For B2B, the channel works hardest when a demand signal already exists, such as a website visit, a downloaded report or a webinar sign-up.

The Social Shepherd is a UK social agency with offices in London and Bath, and it runs paid social on Meta and LinkedIn.

PPC Geeks is a UK PPC agency that offers Meta and LinkedIn ads, with management fees from around £299 per month.

Form fills arrive without a buying role attached, so lead routing needs a rule before the first campaign goes live.

Retargeting, lookalike building and event promotion usually sit here, while the named-account work sits on LinkedIn.

Comparing the two on one brief

LinkedIn Ads

Targeting input: Job title, seniority, company size, uploaded lists
Typical B2B job: Named-account lead generation and event promotion
Creative demand: Lower volume, document-led formats
Main measurement risk: Lead form quality and job-role accuracy
Agency examples: The B2B Marketing Lab, Digital 22, Fifty Five and Five
Asset the client should own: Company lists and lead exports

Meta Ads

Targeting input: Interests, behaviour, lookalikes, site activity
Typical B2B job: Reach, demand capture and retargeting
Creative demand: Higher volume, short video and static
Main measurement risk: Form spam and low buying intent
Agency examples: The Social Shepherd, PPC Geeks
Asset the client should own: Pixel, conversion events and audiences

Read the table as a set of questions, not as a verdict.

Neither column predicts your own cost per qualified lead, and no agency can promise it before a test.

A specialist who cannot say which row drives the plan is describing media, not strategy.

Account-based marketing: what to verify

Named-account work is the part of a B2B brief that buyers find hardest to verify.

Ask for the list-building method, the exclusion rules and the person who approves the final company list.

Then ask how replies reach the sales team and where that handover is logged.

An account based marketing agency that cannot show those steps is selling media space.

A short document request keeps the conversation concrete:

The account list, its source and the date it was built.
Exclusion rules, including current customers and open opportunities.
The weekly review that decides which accounts receive more spend.
The handover record from form fill to sales owner.

Consent, retargeting and lead data

Retargeting a pricing-page visitor is direct marketing, and the ICO's direct marketing and privacy guidance explains what consent and the soft opt-in require.

Lead forms create a second exposure: the personal data lands in a platform the client may not control.

The contract should say who owns the audience, the pixel and the exit route, which is the ground our comparison of a paid social retargeting agency covers.

Check the lead form wording against the privacy notice before launch, not after.

Common questions

Can one agency run both LinkedIn and Meta for a B2B brief?

Yes. The test is whether one team can answer both a named-account question and a creative-volume question.

How should a UK B2B brand split budget between the two?

Start with your last ten closed deals, then fund the platform that produced them. Keep a small test budget on the other.

What does an account-based marketing agency add to a paid social brief?

Named company lists, exclusion logic and a documented sales handover. Without those, account-based work collapses into ordinary targeting.

Which costs should be agreed before signing?

Media budget, management fee, creative production, tracking setup and the exit fee. Ask for each as a separate line.
