Influencer marketing: the brief, the payment, the disclosure, and the measurement you set up first

An influencer campaign comes down to four decisions and one piece of paper. The decisions are who you work with, what you ask them to make, how you pay, and how you will know whether it worked. The piece of paper is the brief, and a vague brief is the single most common reason a campaign produces content nobody can use. Pick creators on audience fit rather than follower count, write a brief that states the one message and leaves the execution to them, pay for usage rights separately from the post itself, and give every creator a unique code or link before anything goes live.

This page covers running influencer and creator work: selection, the brief, payment models, disclosure obligations, measurement, and the situations where another channel is a better use of the money. For talent management and creator side business advice, that is a different subject.

Choose on fit, not on follower count

A large following in the wrong country, or an audience that watches for entertainment and never buys anything, is worth less than a small following that trusts a recommendation. Before you approach anybody, check:

• Where the audience actually is. Ask for screenshots of their audience location and age breakdown from the platform's own analytics, not a figure typed into a media kit.
• The comments. Real conversation, repeat names, questions about things they recommended. Generic emoji replies in volume are a warning sign.
• How much of their output is paid. A feed that is mostly sponsored posts converts poorly, because the audience has learned to scroll past.
• Who they have worked with, including your competitors, and whether any exclusivity is still running.
• Whether they have ever sold anything. Ask what happened the last time they ran a code. Creators who sell know their numbers and will tell you.
• Growth that makes sense. A following that jumped suddenly without a clear reason deserves a question.

For most brands the answer is several smaller creators rather than one large one. You get more content, more audiences, and a better read on what resonates before spending heavily.

The brief, field by field

Give the creator this, in writing, before any money moves:

CAMPAIGN      name, and the date the content must be live
THE AUDIENCE  who you want reached, in plain words
THE ONE THING they should take away. One sentence. Not five.
THE PRODUCT   what is being sent, when, and how to use it
MUST SAY      claims you need included, exactly as worded
MUST NOT SAY  claims that are not permitted, and why
DISCLOSURE    the exact wording and placement required
DELIVERABLES  format, length, platform, quantity, and whether
              raw footage is included
LINKS         the unique link or code for this creator
USAGE RIGHTS  where you may reuse it, in what form, for how long
EXCLUSIVITY   category and period, if any
APPROVALS     one review round, with a named approver and a
              turnaround time
PAYMENT       amount, trigger, and the date it will be paid

Two rules keep briefs useful. Be strict about the message and the compliance wording, and loose about the creative, because the reason their audience watches is a style you cannot write for them. And keep approvals to one round with a deadline, since a brand that sends four rounds of comments gets bland content and a creator who declines the next campaign.

How to pay

Model	How it works	Suits
Flat fee per deliverable	A set amount for agreed posts or videos	Most campaigns. Predictable for both sides
Usage or licensing fee	A separate payment to reuse the content in your own ads, site or email	Anything you intend to run as an advert. Price it from the start
Affiliate or commission	Payment on sales through a code or link	Products with a short decision and a healthy margin
Product only, or gifting	No fee, product sent, no obligation to post	Seeding and sampling at volume, not for specific deliverables
Ambassador retainer	Monthly fee over several months	Repeated exposure, which is where trust is actually built
Amplification rights	Permission to run paid media from their handle	Content that performs well organically and deserves budget

Three things to settle before signing. Usage rights are not included in a post fee, so agree the term and the territory in writing. Exclusivity has a price, because you are asking somebody to turn down work. And pay on the agreed date, since the creator community talks and a reputation for slow payment closes doors quietly.

Disclosure is a legal matter, not a courtesy

Paid and gifted content has to be identifiable as advertising, and the brand carries responsibility alongside the creator. In the United States the Federal Trade Commission sets this out in its disclosures guidance for social media influencers and in the endorsement guides. In the United Kingdom, the advertising codes apply to creator content in the same way they apply to any other advert. What good practice looks like in both places:

• The disclosure sits where the audience sees it before engaging with the content, not after a tap on more, and not in a profile bio.
• Plain words beat jargon. Ad, advert and paid partnership are understood. Abbreviations like sp or collab are not.
• In video, say it out loud as well as showing it on screen, because many people listen rather than read.
• It applies to free products, trips, discounts and affiliate links, not only cash payments.
• Use the platform's own paid partnership tool and clear wording together, rather than relying on the tool alone.
• Claims in the post are advertising claims. If your brand cannot say it on a label, a creator cannot say it in a caption on your behalf.

Measurement that holds up afterwards

• A unique code and a unique link per creator, set up before launch. This is the only part of the plan that is impossible to retrofit.
• A landing page per campaign so traffic is attributable and the arrival matches the content.
• Post level figures from the creator, requested in the contract, taken at least a week after posting, and ideally again at thirty days, because short video keeps earning views for weeks.
• Watch saves, shares and sends ahead of likes. Those are the actions that correspond to somebody intending to buy.
• Measure cost per acquired customer, not cost per thousand impressions, and compare it with your other channels.
• For brand level work, hold a region back. Run the activity in some areas and not others, then compare direct and branded search demand between them. That comparison is the cleanest read available on content that cannot be tracked click by click.

Creator content as advertising, which is a different exercise

Separately, you can commission creators purely to make content you then run as paid advertising. The audience is yours, the creative is theirs, and the measurement is ordinary advertising measurement. It is cheaper per asset, easier to test, and it needs the same disclosure treatment once it runs as an advert.

When another channel is the better answer

• Long, committee led B2B purchases. Where procurement, security review and a business case stand between interest and signature, the money goes further into account led work and industry credibility.
• Heavily regulated claims. Where every claim needs clearance, the approval burden often outweighs the reach.
• Products that need a demonstration. If the value takes twenty minutes to show, a short video sets the wrong expectation and the returns follow.
• A retention problem. New attention makes a leaky product worse. Fix the experience first.
• No landing page and no stock. Interest arrives in a day and goes nowhere.
• A need for volume next week. Creator timelines run in weeks, and search or paid social respond faster.

What gets asked about influencer marketing

How many creators should a first campaign use?

Enough to compare, which usually means a handful rather than one. Treat the first round as a test of audiences and messages, then put the budget behind what worked.

Should we let creators keep creative control?

Control the message and the compliance wording, and hand over the execution. Content that sounds like the brand wrote it performs worst.

Is gifting enough to get posts?

It gets some posts, unpredictably, and it is a sampling tactic rather than a campaign. When you need specific deliverables on a specific date, pay for them.

Who owns the content afterwards?

Whatever the contract says. By default the creator holds the copyright, so if you want to reuse it, licence it explicitly with a term and a territory.

What is the most common mistake?

Launching without unique codes, links or a landing page, which leaves you arguing about whether it worked instead of knowing.

Where a creator's review gets read back to a buyer

A creator posts a review, the audience watches it, and the campaign report counts views. The review does not stop there. Transcripts, captions and the articles written about it become sources, and an assistant may repeat the creator's verdict when a stranger asks what to buy.

That is worth knowing when you write the brief, because the claims you allow in the video are the claims that can travel. After a campaign, ask an assistant the product question and see what it says and who it cites. AI Knows Us records that for a fixed set of questions.
