Performance marketing analytics for e-commerce

Find the products burning your ad budget.

PMK Core joins ad cost, revenue and purchases per product, splits your catalog into 7 performance segments, and pushes them back into Google & Meta as feed labels — automatically, on every run.

PMK Core dashboard: revenue vs ad cost, wasted budget percent, segment KPIs

Ad platforms optimize campaigns. Your money is lost per product.

Three things go wrong in every large catalog:

Budget burns silently

In a typical catalog, 15% of products eat ad spend and never sell once. Campaign averages hide them completely.

Networks grade their own homework

Google and Meta report conversions your database never saw. We call these Grey Holes — and we find them.

Too many SKUs to manage by hand

At 10,000+ products, nobody checks cost against revenue per SKU. So nothing gets fixed.

Seven segments. One decision each.

Every run, PMK Core ranks your whole catalog on two axes — ad cost, and revenue with purchases — and lands every product in exactly one segment with a clear action.

→ Ignore, for now

A real catalog distribution: nearly half the products are Phantoms, and 15% are Black Holes quietly spending with zero return.

How it works

Step 1

Connect

Google Ads, GA4, Google Merchant — plus Meta Ads, sales & COGS data.

Step 2

Run

A scheduled run matches cost, revenue and purchases to every product — an immutable snapshot.

Step 3

Segment & act

The 7 segments, drill-downs to product level, and a prioritized action list.

Step 4

Export

Segments flow back to Google & Meta as supplemental-feed custom labels. Campaigns restructure around them.

For store owners

Stop paying for products that never sell, protect your margin, and let the feed labels do the campaign work — without hiring an analyst.
