What does the Google Shopping Feed & Tracking Audit check?

This is the technical side of feeds and tracking – scoped deliberately apart from campaign management. The audit checks whether the data flowing into Google Merchant Center, GA4 and Google Ads is complete, accurate and trustworthy, because everything downstream (free listings, Shopping ads, performance reporting) depends on that foundation being sound. We examine:

• Merchant feed quality – required attributes, titles, GTINs, disapprovals and policy issues. We check that products carry the attributes Google expects, that titles are structured to match how people search, and that disapprovals or policy flags aren't quietly suppressing part of your catalogue.
• GA4 / Ads tracking – conversion firing, deduplication, and whether your numbers can be trusted. We verify that conversions actually fire, that they aren't double-counted, and that the figures you base decisions on reflect reality.
• Product / Offer schema – structured data that backs free listings and rich results. Correct Product and Offer markup helps your catalogue qualify for free Shopping listings and rich results in search.
• Product-data quality – the catalogue data feeding both your feed and your on-site SEO. The same PrestaShop product data drives the feed and the storefront, so cleaning it up improves both at once.

Why it matters

Feed and tracking problems are insidious because they're invisible day-to-day: a missing GTIN, a malformed title, or a conversion tag that fires twice doesn't throw an error – it just quietly distorts your data and suppresses reach. In PrestaShop, feeds are typically generated by a module mapping catalogue fields to Google's attributes, and small mapping gaps multiply across thousands of products. This audit finds those gaps before they cost you visibility or mislead your campaign decisions. It's for owners who run (or plan to run) Shopping and want confidence that the underlying data is right.
