Measure real Instagram Ads profitability for a jewelry store

Typical average order
30 to 120 euros depending on positioning

The context

Jewelry stores often have Instagram as their primary acquisition channel, mixing image campaigns with more transactional ones. Visuals drive sales, but margins vary a lot by category (silver, plated, gold-plated, etc.).

The ad platform's ROAS gives a first indication, but it doesn't integrate COGS, Stripe fees or returns. To know if Instagram Ads is truly profitable, you need to switch to POAS.

Typical pain points

Misleading Instagram ROAS

The Meta Ads ROAS on Instagram may look fine while net margin, after COGS and returns, is far more fragile.

Heterogeneous margins per line

Depending on material or collection, gross margin varies a lot. Campaigns scaling low-margin lines can erode overall profitability.

Underestimated returns

In jewelry, returns exist (sizing, perceived quality) and must be included in advertising profitability calculations.

Creative-only piloting

Creative teams often optimize on feel or CTR, without reading real profitability by creative or ad set.

What Fullmetrix can bring

Automatic POAS computation

Fullmetrix computes POAS per campaign, ad set and creative, integrating COGS, fees and returns, giving the economic read the ad platform doesn't provide.

Reading by collection or line

It becomes possible to see which collections or lines truly perform once margin is taken into account, beyond raw volume sold.

Product margin tracking

Per-product net margin reports help identify truly profitable best-sellers vs. those that just generate top-line revenue.

Alerts on critical POAS

Alerts can flag a campaign dropping below a POAS threshold, before significant budget is spent on a weakly profitable mechanic.

What you can expect to measure

The items below are metrics typically observable on this profile, not numerical guarantees. Impact depends on product mix and ad account maturity.

Honest view of Instagram profitability

Know which Instagram Ads campaigns truly contribute to profit and which deserve to be cut.

Collection-level arbitration

Steer ad investment toward genuinely profitable collections rather than those that only display a good CTR.

Better-identified best-sellers

Distinguish volume best-sellers from those actually pulling margin, to structure the catalog.

Savings on loss-making creatives

Spot sooner creatives whose POAS drifts and reallocate to mechanics that work.
