How to Run an Influencer Campaign That Actually Sells

An influencer campaign works when it is run as a media buy with a creative brief attached, and it fails when it is run as a series of favours. The difference is whether you decided, before contacting anyone, what commercial job the campaign is doing.

This post sets out the sequence: goal, creator selection, brief, rights, launch and measurement. It is written for founder led DTC brands at $5M to $30M who are running this in house rather than through a specialist agency.

What should the campaign be for?

Pick one of three jobs and say it out loud: reaching people who have never heard of you, giving people who already know you a reason to trust you, or producing content you will then run as paid ads.

Those three need different creators, different briefs and different measures. Reach wants audience size and relevance. Trust wants credibility and a real relationship with the product. Content production wants someone who is good on camera, and audience size barely matters at all, which is why the third job is usually the cheapest and the most reliably profitable.

Most disappointing campaigns are a trust brief judged on reach numbers, or a content brief paid at reach prices.

How many creators should a campaign use?

Fewer, working harder. One creator posting three times over six weeks builds more than three creators posting once each, because repetition is what converts recognition into trust.

The exception is the content production job, where breadth matters more: if you are buying assets to run as ads, a wider set of faces and formats gives the delivery system more genuinely distinct creative to work with. Distinct is the operative word. Ten creators reading the same script in the same format reads as one concept.

What goes in the brief?

The job, the audience, the one thing the viewer should understand, the hard rules, and the freedom. In that order.

The single most common mistake is briefing a script. A creator's audience follows them for their voice, so a brand voice script strips out the thing you paid for. Brief the point rather than the wording, specify the non negotiables such as claims, competitor mentions, disclosure and safety language, and let the rest go.

Include what the ad has to do rather than only what it has to say. If the content will run as paid media, say so in the brief, because a hook that works organically for an audience that already knows the creator is not the same hook that works cold.

What rights do you need to agree up front?

Paid usage rights, the duration, the territories and the platforms. Agree them before the shoot, never after.

Retrofitting usage is expensive and sometimes impossible, and the cases where an influencer campaign produces a genuinely outstanding asset are exactly the cases where you will want to run it as an ad for six months. Buying that right at the point of booking costs a fraction of buying it once both sides know the asset works.

Whitelisting, where you run ads from the creator's own handle, is a separate permission again and needs its own agreement. That is covered in influencer whitelisting and creator licensing.

How should creators be paid?

A flat fee for the content and the rights, with performance elements as an addition rather than a replacement.

Gifting alone works only for creators who genuinely want the product and have small audiences. Affiliate only deals attract creators who are optimising for their own conversion rate rather than for your brand, which usually means discount led content. A flat fee buys the brief being followed; a performance element buys enthusiasm on top.

When should a peak campaign go live?

Content should be shot and approved well before it is needed, which for Black Friday on 27 November means briefing in October. Creator content carries a longer lead time than a static, and the failure mode is a creative bank that arrives the week it was meant to start running.

The timing detail sits in the creative bank production deadline, and the wider question of what gets briefed when is in the creative chapter of the Q4 Profit Playbook, free and written for founder led DTC brands on Shopify at $5M to $30M.

How do you measure it?

On contribution, with reach as a diagnostic rather than a result.

Three numbers are worth having. Total cost of the campaign including fees, product and rights. New customer volume during and shortly after the activity, against your baseline. And the cost per new customer that implies, compared with what the same money would have bought in paid social.

Discount codes and affiliate links are useful for attribution and structurally understate influencer work, because a large share of the effect is people who saw the content, searched your brand later and bought without the code. Watch branded search volume and direct traffic across the campaign window as a supporting signal.

If the content is running as paid ads, that part is measurable normally, and it is usually where the clearest return sits. Webtopia briefs, licenses and runs creator led work for founder led brands as a performance creative agency.

Frequently asked questions

How do you run an influencer campaign for an ecommerce brand?

Decide the commercial job first, select creators against that job, brief the point rather than the script, agree paid usage rights before the shoot, and measure on new customer cost rather than reach.

How many influencers should a campaign use?

Fewer creators posting repeatedly beats many posting once, except when the goal is producing ad assets, where a wider set of genuinely different formats is worth more.

Should influencers be paid a flat fee or commission?

A flat fee for content and usage rights, with performance elements added on top. Affiliate only deals tend to produce discount led content.

When should influencer content be briefed for Black Friday?

October. Creator content has a longer lead time than a static, so anything intended for peak needs briefing, producing and approving before November.

How do you measure influencer marketing without a discount code?

Compare new customer volume and cost against your baseline across the campaign window, and watch branded search and direct traffic. Codes capture only part of the effect.
