Funnel coverage

One grid that shows where your money is leaking.

Rows are funnel events. Columns are the platforms you actually run. Each cell is found, missing, malformed or duplicated. It's the one view a plugin will never give you - and the one agencies pay attention to.

A simplified example. Your real report is built from what we detect on your store.

The killer finding. If a column has a pixel (the ads are running) but the Purchase row is empty, you're paying for advertising while the conversion signal never arrives. That single cell is worth more than every "is the tag installed?" check combined.

What each cell actually checks

Found, but correct?

  • purchase carries value, currency, transaction_id, items[]
  • value is a number, currency is ISO 4217 (EUR/USD)
  • item rows have item_id, item_name, price, quantity

Or quietly broken?

  • the same transaction_id sent twice (refresh on thank-you = double revenue)
  • a duplicate config tag double-counting everything
  • value/currency mismatched between GA4 and Meta
