Every agency that runs influencer campaigns has seen the slide: a campaign that cost a modest amount, and beneath it an earned media value several times larger, presented as if the difference were profit. The client nods, the agency moves on, and some months later a finance director asks how a campaign worth that much did not show up anywhere in sales.
EMV is not a dishonest number. It becomes one when it is asked to answer a question it was never designed to answer. The way to report influencer work honestly is to know what each number measures, and to put the right one at the top.
What EMV actually measures
Earned media value estimates what the attention a campaign earned would have cost to buy as advertising. The formula is simple: impressions divided by 1,000, multiplied by the CPM, which is what paid media would cost to reach the same audience a thousand times.
As a worked example, if a campaign's posts earned 400,000 impressions and comparable paid social costs AED 30 per thousand, the EMV is AED 12,000. That is a comparison with paid media. It is not revenue, it is not return on investment, and it says nothing about whether anyone bought anything.
The CPM is where the honesty lives
The whole of EMV rests on one assumption, the CPM, and it is the assumption nobody checks. Double the CPM and the EMV doubles. A figure borrowed from a different market, or a premium placement, or simply picked because it produced a pleasing number, can make any campaign look like a success.
Three rules keep it defensible:
- Use a CPM you could defend to the client, ideally one drawn from what their own paid social actually costs in that market.
- State it in the report, beside the EMV, every time.
- Keep it the same from month to month, so a rising EMV means the campaign improved, not that the assumption did.
The ROI calculator on this site starts from AED 30 per thousand impressions, a common starting point for Gulf agencies, and lets you change it. Treat it as a placeholder. Replace it with the rate your client agrees to, and write that rate down.
Be wary of anything that multiplies the result for credibility or influence. That is the same move that made advertising value equivalency, the old PR measure, so hard to defend, and the measurement industry has spent years moving away from it.
The numbers that are just division
Several of the most useful campaign figures involve no assumption at all. They are one number the platform or the creator reported, divided by another you already know. That makes them harder to argue with than EMV.
- Effective CPM: spend divided by impressions, multiplied by 1,000. What the campaign actually paid for each thousand impressions.
- Cost per engagement: spend divided by total engagements, counting likes, comments, shares and saves.
- Engagement rate: engagements divided by impressions.
- Frequency: impressions divided by reach, which shows how often the same people saw the content.
- Cost per click, and cost per acquisition when conversions are tracked.
Effective CPM is the honest version of the question EMV is trying to answer. Instead of pricing the impressions at a notional rate and admiring the total, it asks whether the creators delivered attention more cheaply than paid media would have. If the campaign's effective CPM is below what the client pays for comparable ads, that is a real finding. If it is above, the campaign needs another justification.
ROI needs revenue, and revenue needs tracking
Return on investment is revenue minus spend, divided by spend. Return on ad spend is revenue divided by spend. Neither can be calculated without revenue that can be traced to the campaign, which in practice means a discount code, a tracked link or a dedicated landing page agreed before anyone is booked.
As a worked example, suppose a client spends AED 24,000 on creators, the posts earn 600,000 impressions, and a code brings in AED 36,000 of sales:
- EMV at AED 30 per thousand: AED 18,000, which is less than the spend.
- Effective CPM: AED 40.
- ROAS: 1.5, meaning every AED 1 brought back AED 1.50 in sales.
- ROI: 50%.
Two cautions apply. Tracked sales undercount, because people see a post and buy later without the code, so treat them as a floor. And ROAS counts revenue, not profit. On a product with a thin margin, a ROAS of 1.5 may still lose money once the cost of the goods is taken off, so agree a break-even figure with the client before the campaign runs.
A campaign can have a strong EMV and sell nothing, or a modest EMV and pay for itself. The report should make it obvious which one happened.
Where the inputs come from
Every one of these figures depends on impressions, reach and engagement, and for influencer posts those come from the creator's own insights. Write the reporting obligation into the agreement: which metrics, in what form, and by when. A common arrangement is within seven days for feed posts and within 24 hours for stories, because stories drop out of insights quickly.
Figures gathered weeks later, as cropped screenshots with no date, are not something an agency should put its name to. If a number could not be verified, say so in the report rather than estimating it.
What to put at the top
Match the headline to the objective agreed at the start. An awareness campaign is reported on reach, frequency and effective CPM. A campaign meant to sell is reported on cost per acquisition, ROAS and ROI. EMV can support either story, stated with its CPM, but it should not be the headline of a campaign that was meant to sell.
Wiro's monthly client reports list influencer posts with their reach, likes, comments and value beside the rest of the month's work, so the numbers sit in one place. The discipline of choosing which one leads is still the agency's, and it is the part clients remember.
