How to measure product seeding ROI: EMV vs in-market reach

Get the cost side right first

Most seeding ROI numbers are wrong on the bottom of the fraction, not the top. Gift cost should be:

• Product at your cost, not retail.
• Packaging and inserts.
• Shipping, including reships.
• Any fees, if it was a paid deal or had an affiliate commission.
• Optionally, team time. Leave it out if you like, but be consistent.

Counting product at retail inflates cost and makes seeding look worse than it is. Leaving shipping out does the opposite. Pick a definition and keep it for every drop.

Count before you value

Before any dollar estimate, track the counts. They are hard to argue with and they tell you whether the list is working.

• Delivered: boxes that actually arrived.
• Posted: people who posted at least once about the gift.
• Post rate: posted divided by delivered. The best single measure of list quality.
• Posts: total pieces of content, by format.
• Views and engagement on each post, where you can get them.

What EMV measures, and what it does not

Earned Media Value estimates what the reach and engagement from a post would have cost if you had bought them as advertising. A typical calculation multiplies impressions by a cost per thousand (CPM) for that placement, and sometimes adds a value per like, comment or share.

Why teams use it

• It produces a dollar figure from data you already have.
• It is widely reported, so it is familiar to clients and leadership.
• It lets you compare posts and drops against each other quickly.

Where it falls short

• It values attention, not buyers. A million views from people who will never buy your category still scores high.
• Every vendor uses different CPMs and engagement weights, so EMV from two tools cannot be compared.
• It assumes an organic post is worth what an ad would cost, which is a pricing assumption, not an outcome.
• It tends to favor large accounts, even when smaller, specific talent drove more real interest.

EMV is a reasonable comparison metric. It is a weak answer to "did this gift sell anything?"

A buyer-based method: In-Market Reach and Value

The Comms method starts from the same post data but asks a narrower question: how many people who saw this are realistically shopping for this kind of product? We call that In-Market Reach (IMR).

• In-Market Reach (IMR) = views × engagement rate × category intent. Views are the people who saw it. Engagement filters to people who paid attention. Category intent is the share of those people who are in the market for that kind of product.
• In-Market Value (IMV) = IMR × close rate × price. The sales those in-market people are likely to drive.
• ROI = IMV ÷ gift cost. Whether the gift paid for itself, and how many times.

Why we think it is more honest

• It produces a smaller number than EMV, on purpose. It is easier to defend in front of a finance team.
• It rewards fit: a specific audience with high category intent beats a large general one.
• Every input is visible, so you can argue with the assumptions instead of trusting a black box.

Where it falls short too

Category intent and close rate are estimates. They start from category benchmarks and should be replaced with your own numbers as real sales data comes in from codes, links or post-purchase surveys. Treat IMV as a planning estimate, not attributed revenue. Comms reports EMV alongside IMR and IMV for teams that need both.

Adding hard attribution where you can

Estimates are more convincing next to some direct evidence. Cheap ways to get it:

• Unique discount codes per talent. Undercounts, because many buyers never use the code, but it is real.
• Tracked links in bios or Stories, with UTM parameters.
• Post-purchase surveys asking "where did you hear about us?", with talent names as options.
• Lift during the drop window in the regions or categories you seeded, compared with a baseline.

Use these to calibrate your close rate and intent assumptions over time. That is how a buyer-based estimate gets sharper.

How to report seeding results

A good seeding report fits on one page and answers four questions: what did we send, who posted, what did it reach, and was it worth it?

• Boxes sent and delivered, and all-in cost.
• People who posted, post rate, and number of posts by format.
• Views and engagement totals.
• IMR, IMV and ROI, with the assumptions stated.
• EMV, if your client or leadership expects it, labeled as an ad-equivalent value.
• Any hard attribution: code uses, link clicks, survey mentions.
• The top five posts, with links.
• Who to re-gift, who to pay, and who to drop next month.

Agencies can send this as a branded recap link instead of a deck. See Comms for agencies.

Common measurement mistakes

• Using retail price as gift cost.
• Comparing EMV across tools with different formulas.
• Counting only posts that tagged you, and missing the ones that did not.
• Measuring too early. Gifted posts can go up weeks after delivery, so leave a window before closing the report.
• Changing the method every month, so nothing is comparable.
