B2B influencer marketing: a 90-day pilot framework

What to take away

The most common mistake is treating the first ninety days as a campaign. It is a decision period with a fixed end point.
Pick one objective, one audience segment and two or three creators. Sprawl kills pilots.
Build the legal basis for outreach before the target list.
Weeks 1 to 4 are set-up, weeks 5 to 10 delivery, weeks 11 to 13 the scale-or-stop call.
Write stop criteria on day one, while you are still detached from the result.

Why ninety days is a decision window, not a campaign

A quarter tests whether a creator can move a B2B audience, and caps the cost of being wrong. Treat the endpoint as a governance gate.

Ninety days as a decision window

Day 0
Fix the decision date
Days 1-14
Define objective and audience
Days 15-30
Outreach and legal groundwork
Days 31-60
Run the pilot
Days 61-90
Scale or stop call

Teams that skip this framing extend a failing pilot twice, then report a vague success. Fix the decision date before any creator conversation begins.

For the wider context, the strategy and planning guide shows how objectives, budgets and measurement fit together across a year.

Days 1 to 14: define the objective and the audience

Write one sentence naming the business outcome, such as pipeline from a named sector or reach into a job title cold email cannot open.

Weak versus testable audience

Weak

Who: Decision makers in financial services
Where: No named firms
Outcome: Vague reach

Testable

Who: Heads of risk
Where: Twenty named building societies
Outcome: Pipeline from named sector

For example, a team selling compliance software into UK building societies might target heads of risk at twenty named firms. "Decision makers in financial services" is not a testable audience.

LinkedIn, a newsletter and a webinar each demand different creative and different proof. Our guide to channel strategy matches format to objective rather than copying a consumer playbook.

Days 15 to 30: build the outreach and legal groundwork

For outreach involving personal data, UK GDPR requires a lawful basis. Legitimate interests may be appropriate for direct marketing where a documented assessment supports it, but PECR separately governs electronic marketing. Its requirements differ for individual and corporate subscribers, so check the recipient type and current ICO guidance before sending. Record the basis, assessment and any consent or objection.

Keep a register of who you contacted, when, on what basis, and what they said. An hour a week saves months if a query arrives.

Shortlist six to eight creators, checking recent work for audience fit, disclosure habits and whether they publish for a business readership.

When comparing agencies or tools, check how a provider structures vetting and reporting. A review of Linqia's agency model is a useful reference for procurement questions.

What to put in the creator brief

One paragraph on the audience, one on the message, one on the call to action. Put the disclosure requirement in the contract.

What to leave out

Do not ask creators to hide the commercial relationship. In the UK, advertising must be obviously identifiable under the CAP Code, administered by the ASA; the CMA also publishes guidance on influencer marketing. Put clear ad labelling, such as “Ad”, in the brief and contract.

Days 31 to 60: run the pilot and collect evidence

Brief two or three creators, not eight. Fewer partners means cleaner attribution and a faster read.

Agree the measurement before content goes live: qualified visits, named-account engagement, replies to the creator, or meetings booked.

Run a weekly thirty-minute review. Note what the audience asked and where the creator pushed back on your messaging. That feedback often beats the impressions.

The FTC publishes studies on advertising practices, including research on influencer disclosure, useful if part of your audience sits in the United States.

Days 61 to 90: review, then scale or stop

Hold the decision meeting in week 11, not week 13, so you have time to act.

Score against the criteria written in week one. If the pilot missed them, stop. A clean stop frees budget for a better-targeted test.

If it worked, scale one variable at a time: more creators in the same segment, or a second format. Changing all three makes the next quarter unreadable.

Common questions

How many creators should a first ninety day plan include?

Two or three. More and you cannot tell which partner produced the result.

Do we need a contract before the first post?

Yes. It should cover deliverables, timing, disclosure, usage rights and what happens to the content after the pilot.

What if the pilot delivers reach but no pipeline?

Treat it as a format or audience problem, not automatically a creator problem. Check whether the call to action matched the audience's stage.

Can we run this without a dedicated budget line?

It can work, but the pilot competes with existing activity for attention. A named budget, even a small one, keeps the ninety days honest.
