What an Influencer Campaign Performance Report Should Actually Contain
There is a version of the influencer campaign report that exists to make the agency look good, and a version that exists to help you decide what to do next. They are easy to tell apart. This is what the second one contains.
Per creator, not per campaign
A campaign-level summary tells you the campaign happened. It cannot tell you anything actionable, because the whole point of running several creators is to find out which ones work for you.
Every metric in the report should be broken out by creator. When it is, the pattern is usually obvious within a minute: a couple of clear performers, a long middle, and one or two that cost real money and returned nothing. That distribution is the finding. A blended average hides it completely.
The metrics that belong in it
Roughly in order of how much they should influence your next decision:
- Cost per result — spend on that creator divided by the outcome you actually cared about. The single most decision-useful number in the report.
- Conversions or tracked actions, where a code, link or landing page makes attribution possible.
- Clicks and click-through rate, which tell you whether the call to action worked even when purchase tracking is imperfect.
- Engagement rate benchmarked against your own campaign average rather than an industry figure — an external benchmark is chosen to flatter, your own average is not.
- Reach and impressions, which belong in the report but belong near the bottom of it.
The numbers most reports leave out
Two omissions are common enough to be worth checking for specifically.
The first is underperformance. If every creator in the report looks like a success, the report is a selection, not a measurement. You want the ones that did not work named, with a view on why — wrong audience, wrong format, wrong timing, or simply a creator whose audience does not respond to paid content.
The second is what the campaign cost in total, separated into what went to creators and what went to the agency. If those two numbers are blended into one figure, you cannot evaluate either the creators or the agency, which is usually the reason they are blended.
Attribution: be honest about what you can and cannot know
Influencer attribution is genuinely imperfect. Someone sees a video on a phone, thinks about it for three days, and later searches your brand name directly. No tracking link captures that, and a report claiming otherwise is overstating its own precision.
The reasonable approach is to state the confidence level alongside the number. Tracked conversions through a unique code are near-certain. A lift in direct traffic and branded search during the campaign window is suggestive but not proof, and should be labelled that way. A report that distinguishes between the two is more trustworthy than one that presents everything as hard data.
It should end with a recommendation
The report's last section should say plainly which creators to run again, which to drop, and what to change about the brief next time. Not a dashboard for you to interpret — a call, with the reasoning shown.
That is the difference between reporting and measurement. Reporting tells you what happened. Measurement tells you what to do about it, and is the only reason to spend time reading it.
