How to Run an Influencer Campaign: Selection, Briefs, Disclosure and Measurement

In this article10 sections

Quick answer

A good influencer campaign starts with one clear goal, then selects creators whose audience matches your customers rather than those with the biggest following. Write a brief that fixes the essentials but leaves room for the creator's voice, put terms and disclosure rules in writing, and measure with tracked links, codes and agreed metrics. Every paid or gifted post must be clearly disclosed as advertising.

This guide is for brands and service businesses planning their first influencer campaign, or trying to make the next one more structured. It covers goals, finding and vetting creators, briefs and contracts, disclosure rules from regulators, and how to measure whether the campaign was worth it.

What should an influencer campaign achieve?

Pick one primary goal before you contact anyone, because it determines which creators, formats and metrics make sense. A campaign that tries to do everything is hard to brief and impossible to judge.

How do you choose the right influencers?

Choose for audience fit, content quality and trustworthiness, in that order. Follower count is the least useful number on a profile.

A vetting checklist

• Audience match: ask for audience insights showing location, age range and gender split, shared as screenshots from the platform's own analytics.
• Engagement quality: read the comments. Real questions and conversations matter more than emoji strings or generic praise.
• Consistency: steady views and engagement across recent posts, not one viral outlier.
• Content fit: does their style suit your brand, and would your product look natural in their feed?
• Brand safety: review past content and other brand partnerships for conflicts or concerns.
• Disclosure history: creators who already label sponsored posts properly are easier and safer to work with.
• Professionalism: clear communication, rate cards and willingness to sign an agreement.

Warning signs of inflated audiences

Watch for sudden jumps in followers, engagement that does not match follower count, large numbers of comments that could fit any post, and audiences concentrated in places your business does not serve. The US Federal Trade Commission's rule on consumer reviews and testimonials prohibits buying or selling fake indicators of social media influence, such as fake followers or views, so this is a legal issue as well as a waste of budget.

What should an influencer brief include?

A brief should make the goal, the must-haves and the rules unmistakable, while leaving the creative execution to the creator. Their audience follows them for their voice, not yours.

1. Background: who you are, the product or service, and who it is for.
2. Goal: the single outcome you want and how it will be measured.
3. Key messages: two or three points to communicate, in plain language.
4. Must-haves: product shown in use, the tracked link or code, the call to action.
5. Don'ts: claims they must not make, competitor mentions, sensitive topics.
6. Disclosure requirements: exactly how the post must be labeled.
7. Deliverables and timeline: formats, number of posts, draft and live dates.
8. Approval process: what you review, how quickly you respond and what counts as a reasonable change.

Be careful with product claims. Creators should only describe their honest experience, and any claim about results, health or performance must be something your business can substantiate.

What should the agreement with an influencer cover?

Put every important term in writing before content is created. A short, clear agreement prevents most disputes.

• Deliverables, formats, platforms and posting dates.
• Fees, payment schedule, and what happens if dates slip.
• Content approval rights and number of revision rounds.
• Usage rights: whether you can reuse the content in ads or on your website, for how long, and on which channels.
• Exclusivity, if any, and its time period.
• Disclosure obligations and the creator's agreement to follow them.
• Performance data the creator will share after posting.
• What happens if a post is removed or the partnership ends early.

How must sponsored influencer posts be disclosed?

Any post where the creator was paid, gifted products or has another material connection to your brand must clearly say so. Both the brand and the creator can be held responsible.

• United States: the FTC's Endorsement Guides and its "Disclosures 101 for Social Media Influencers" guide ask for clear, unambiguous disclosures placed in the post itself, such as "ad" or "sponsored", and say a disclosure only in a profile bio is not enough.
• United Kingdom: the ASA and CAP guidance for influencers expects ads to be obviously identifiable, typically with a clear label such as "Ad" at the start.
• India: ASCI's guidelines for influencer advertising in digital media require an upfront, prominent disclosure label.

Use the platform's own branded content tools as well, such as the paid partnership label on Instagram and Facebook, the content disclosure setting on TikTok, and the paid promotion setting on YouTube. Regulators generally treat these as helpful additions rather than a replacement for a clear disclosure in the content. Check the current guidance in each country your campaign targets.

How do you measure an influencer campaign?

Agree the metrics in advance, use tracking that does not depend on screenshots alone, and compare cost against the outcome you set as your goal.

• Unique links with UTM parameters per creator, so analytics shows visits, enquiries and sales by source.
• Unique discount codes per creator, to capture buyers who do not click links.
• Platform insights shared by the creator: reach, views, watch time, saves and link clicks.
• Branded search and direct traffic during and after the campaign, as a softer signal.
• Cost per result: total spend, including product and fees, divided by the outcome you care about.
• Content value: how reused creator content performs in your own ads and pages.

Our influencer marketing service sets up this tracking before the first post goes live, because results that are not tracked from day one cannot be recovered later. For UTM setup, see our UTM tracking guide.

Frequently asked questions

Are micro-influencers better than big influencers?

Not automatically. Smaller creators often have close, engaged communities in a specific niche, which can suit consideration and sales goals. Larger creators can deliver broad reach for awareness. Choose based on audience match and the goal, then test with a few creators before scaling.

Do gifted products need to be disclosed?

Yes. Regulators such as the FTC in the US, the ASA in the UK and ASCI in India treat free products as a material connection that should be disclosed, even when there is no payment. Make disclosure part of any gifting agreement.

How much should I pay an influencer?

Rates vary widely by platform, niche, audience size, deliverables, usage rights and exclusivity. Ask several suitable creators for rate cards, compare them against the specific deliverables, and budget separately for product, production and usage rights. Avoid paying purely on follower count.

Can I reuse influencer content in my ads?

Only if your agreement grants usage rights for that purpose, channel and period. Many creators charge extra for paid usage or whitelisting. Agree this before the content is made, including how long you may use it, and keep disclosures in place whenever you reuse it.

How many influencers should I start with?

Start with a small test group that lets you compare creators and formats without spreading the budget too thin. Track each creator separately with their own link and code, then use the results to decide whom to work with again and what to change before scaling.
