A campaign generates add-to-cart events while sales stay flat. The immediate temptation is to blame low-quality traffic, but duplicated cart events or a missing purchase event can produce the same dashboard. Start with real orders and a reproducible buyer journey, then analyze the stage that actually fails.

How to run the investigation
Reconcile completed orders
Use the store’s completed orders as the operational starting point. Align the store, analytics and Meta time zones and currencies. If orders exist but purchase events do not, investigate collection and attribution before declaring the campaign incapable of selling.
Follow the checkout path
Test the promoted product, variant, stock status, delivery region, shipping charges and payment options. Use a test flow approved by the store owner. A working product page does not establish that checkout works in the country taking the spend.
Check event integrity
Review cart, checkout and purchase events for repeated firing and identifiers with the implementation owner. Do not infer a real shopping action from an event name alone. Client-side and server-side event deduplication should be inspected in the relevant diagnostics.
Make a stage-specific decision
When events are trustworthy, compare cart-to-checkout and checkout-to-purchase cohorts with matching observation time. Send checkout repairs to the commerce team; test offer or creative expectations only where the evidence points there.

Use these rows to turn the investigation into an action. Add the actual account, date range, evidence and owner before sharing it with a client.
| What you find | Interpretation | Next move |
|---|---|---|
| Orders exist, purchase tracking absent | Measurement issue likely | Repair reporting before evaluating ROAS. |
| Cart events repeat without checkout | Event integrity uncertain | Test firing and deduplication. |
| Checkout drops in one market | Delivery or payment friction possible | Reproduce that country’s buyer journey. |

Worked example: an illustration, not a customer result
Suppose 60 cart events represent only 20 distinct cart actions and the store records four orders. Reporting 60 abandoned carts exaggerates the problem. After reconciling events, compare the real 20-to-four journey and investigate the stage between them. The example illustrates counting discipline, not a normal conversion-rate benchmark.

A question worth asking
Should I switch optimization to add to cart?
Not simply because purchase reporting looks weak. First verify purchase measurement and real order volume. A more frequent proxy can steer delivery toward the proxy rather than the business outcome.
