Everything you'd want to know before you install.
A detailed look at how Google Shopping PrestaShop Module — Merchant Center Feed, AI & Multi-Channel works, why we built it the way we did, and the thinking behind the features above.
The Google Shopping module that fixes itself
A Merchant Center disapproval for missing GTIN or title too short is costly: while the item is disapproved, your product vanishes from Shopping results. This module catches those disapprovals before Google does, thanks to 50+ validation rules, and proposes an automatic fix via AI (Claude, GPT-4o or Mistral) with a configurable confidence threshold. You stay in control of quality while automating the routine corrections.
One catalogue, six export channels
Google Shopping, Bing Merchant, Meta Catalog (Facebook and Instagram), Kelkoo Group, Idealo, LeGuide. The module automatically generates the format each channel expects: Meta namespace, titles truncated to 100 characters, availability mapped to stock_status for Idealo, deeplink added for LeGuide. Going through a European CSS instead of Google CSS lifts your effective bid by about 20% at the same cost.
Five AI assistants, with cost control
Every assistant logs its calls (input tokens, output tokens, duration, success rate). You see your daily and weekly AI cost in the dashboard. With claude-haiku-4-5 or gpt-4o-mini as default models, auto-mapping 1,000 categories costs about one euro. Rewriting 500 titles, about fifty cents.
An actionable 0-100 quality score, not a vanity metric
On a 500-product sample at every generation, the module computes 9 weighted sub-scores: GTIN coverage, image coverage, image quality, title quality, description quality, category mapping, highlight coverage, no open critical disapprovals, shipping present. The total maps to an A+ to F grade with the 5 highest-impact recommendations sorted on top.
AJAX bulk editing, not CSV pingpong
The editor displays up to 50 products per page with their current overrides. Edit a cell, hit enter, it's saved instantly. Select 200 products with the checkbox, apply one value to all, they update in a single request. For larger corrections, CSV export opens your catalogue in Excel and import picks up your changes.
AI Vision for Merchant Center compliant images
The module audits your product images in batches of 25 via Claude Vision or GPT-4o. The AI detects watermarks, overlaid promotional text (Sale, Promo, percentages), background type (white, transparent, lifestyle, cluttered), and the presence of multiple products in a single image. Each image gets a 0-10 score and a list of actionable issues. 30-day cache per image to avoid re-audits.
A/B testing, seasonal forecaster, Google Ads export
For stores ready to industrialise. The A/B system alternates two title variants per 7-day cycle and declares a winner when each variant has at least 500 impressions and a CTR delta above 5%. The forecaster analyses 24 months of order history to tag products in custom_label_4. The Google Ads Editor export generates a CSV directly importable.
Tested compatibility with PrestaShop 8 and 9
Module developed to modern PrestaShop standards: PSR-4 architecture, Symfony admin controllers, XLIFF translations, overrides only through official hooks. Compatible with PrestaShop 8.0 through PrestaShop 9.x. No core override, no modified file. Multistore and multilingual native.
