A PrestaShop tracking and feed audit covering Merchant feeds, GA4, Ads and schema
PrestaShop Product Feed & Tracking Audit is an expert audit for PrestaShop stores that establishes, with evidence, whether your product feed and your conversion measurement tell the truth. Starting it takes read access to Merchant Center, GA4 and Google Ads and an agreed test checkout; the examination itself is done for you.
It settles the situation every advertising merchant recognises: Merchant Center disapproves products without a clear reason, GA4 reports purchases that never match an order, the agency blames the feed, the developer blames the tags, and the budget keeps bidding on numbers nobody vouches for.
The feed side of the audit compares your actual feed field by field with the product data your live store serves. Missing GTIN identifiers and mismatches in price, tax, stock and availability are named together with the specific products they affect, every Merchant Center disapproval arrives with its exact cause instead of a category of guesses, and the product-level findings come as a filterable spreadsheet your team works through row by row.
The tracking side is tested on the storefront through a real recorded checkout, agreed in advance as a low-value test order that is cancelled or refunded afterwards: view, add-to-cart, begin-checkout and purchase are exercised, and what every tag actually fired is recorded under different consent states. That surfaces duplicate Ads or social pixel injections, purchases counted twice, missing or wrong values and currencies, and how the visitor's consent changes what is measured at all. The verdict arrives within 5 to 7 working days of access being granted.
You receive an evidenced verdict on whether your GA4 and Google Ads conversions deserve trust, with the issues ordered by the money and the measurement at stake, so the first fix on the list is the one worth the most.
What does the PrestaShop Product Feed & Tracking Audit cover?
PrestaShop Product Feed & Tracking Audit is purchased expert work with one outcome: numbers you defend with evidence. The map below covers the six sections.
- The feed compared field by field with what the live store actually serves
- Every Merchant Center disapproval traced to its exact cause
- A real checkout performed and recorded, tag by tag
- Consent states examined for what they change in the measurement
- The deliverables: the verdict, the spreadsheet, the recording, the timeline
- The boundary: what the audit diagnoses and what happens with the findings
What does the feed part of the audit find?
The audit compares your actual feed, field by field, with the product data your live store serves. Missing GTIN identifiers, price mismatches, tax mismatches, stock and availability contradictions: each finding is attached to the specific products it affects, not to a percentage.
Every disapproval in Merchant Center is traced to its exact cause. A rejected product stops being a mystery and becomes a row with a reason.
What does the tracking part of the audit test?
A real path through the store: a product view, an add-to-cart, a begun checkout and a completed purchase. The checkout is agreed with you in advance, a low-value test order placed and then cancelled or refunded, so the books stay clean while the measurement is exercised for real. At every step, the audit records what each tag actually fires, not what its settings page claims.
That is where the expensive defects live: an Ads or social pixel injected twice, a purchase counted two times, a value that is missing or in the wrong currency. Each one is documented as recorded behaviour.
What role does consent play in the findings?
The measurement is examined under different consent states, because a tag that fires for consenting visitors and silently vanishes for the rest produces numbers that mislead in proportion to your refusal rate.
The audit records how the consent state changes what is measured at all, so you know which part of your reporting reflects which part of your customers.
What exactly do I receive, and when?
Three things, each usable on its own. A written, evidenced verdict on whether your GA4 and Google Ads conversions deserve trust, with every issue carrying its evidence, the products or events it affects, and its cause. A field-by-field reconciliation of feed against live store, with the product-level findings supplied as a filterable spreadsheet. And the recorded checkout itself: what every tag fired at product view, add-to-cart, begin-checkout and purchase, under different consent states.
The list is ordered by the money and the measurement at stake: the first item is the one costing the most, so the fixing effort starts where it pays. The whole package arrives within 5 to 7 working days of read access being granted to Merchant Center, GA4 and Google Ads and the test checkout being agreed.
Where does the audit end, and what happens next?
The audit is the diagnosis and the ordered list of causes. Correcting the tags, the feed or the consent configuration is separate work, campaign strategy, bidding and ad account management stay with whoever runs your campaigns, and there is no platform to subscribe to or operate: the outcome is a verdict on your store as it stands, not a tool.
The verdict and the ordered cause list go to your developer or agency to act on, and a 14-day email window covers clarification questions about the findings. When you want the faults corrected and then watched month to month, the PrestaShop Marketing Data & Growth Plan continues from exactly the findings this audit produces.

A technical check of Shopping feeds, GA4, Ads tags, pixels, schema and consent before ad spend relies on bad data.
We compare your product feed to the live store and walk the real funnel with tags and pixels firing. The report names the exact disapproved products, price/stock mismatches, missing identifiers, duplicated conversions and mis-valued events that distort spend decisions.

Exact values, tags and products in the finding
A typical Critical finding is: Feed price 19% below storefront because tax rule is ignored - price-mismatch suspension risk - fix feed tax mapping. Other sample rows include 1,240 items disapproved because GTIN maps from an empty attribute, Ads purchase tag double-counting on thank-you reload, GA4 purchase events without value, or Product schema missing price/availability.
FAQ
Why are products disapproved in Merchant Center?
Usually missing identifiers or price/stock mismatches. We pinpoint the exact products and the exact cause.
Can you tell if conversions are accurate?
Yes. We check missing, duplicated and mis-valued conversions across GA4 and Google Ads, including value and currency.
Do you manage campaigns or budgets?
No. This is the technical layer only: feeds, tags, pixels, schema and measurement integrity.
What access do you need?
Store URL, feed source and viewer-level read access to Merchant Center, Google Ads and GA4. We do not change accounts during the audit.
Will the audit disrupt live tags?
No. We observe and capture what fires; implementation is separate.
