- Product-level conversion tracking — Criteo receives detailed product and transaction data for every purchase, enabling precise ROAS calculation
- Dynamic retargeting — Criteo automatically generates personalized ads featuring products each visitor viewed on your store
- Full customer journey tracking — homepage, category, product, cart, and conversion events all captured automatically
- Criteo's AI engine — your conversion data feeds Criteo's machine learning for continuous bid and creative optimization
- Partner ID configuration — single Account ID setup connects your store to your Criteo account
- Massive ad network reach — Criteo accesses 35,000+ premium publisher sites and app environments
- Compatible with PrestaShop 1.7 through 9.x
Criteo is the global leader in commerce media, reaching 2.5 billion monthly shoppers. Their AI-driven retargeting delivers an average of 13x ROAS for e-commerce advertisers. Give Criteo the data it needs to deliver results.
Criteo: The Gold Standard in E-commerce Retargeting
Criteo is not just another advertising platform — it is the world's largest commerce media company, specifically designed for e-commerce. With access to shopper data from over 2.5 billion monthly active users and relationships with 22,000+ advertisers, Criteo's AI engine understands online shopping behavior at a scale no other platform can match.
Criteo's dynamic retargeting is legendary in the e-commerce world. When a visitor browses products on your PrestaShop store and leaves without purchasing, Criteo's engine kicks in: it identifies that user across 35,000+ publisher websites and apps, generates a personalized ad featuring the exact products they viewed (plus AI-recommended alternatives), and places that ad at the optimal time and location for maximum conversion probability.
The average Criteo advertiser sees 13x return on ad spend. But achieving these results requires one thing: getting high-quality data from your store to Criteo's engine. That is the purpose of the Criteo OneTag, and this module handles the complete integration.
The Criteo OneTag: Purpose-Built for Commerce
The Criteo OneTag is a sophisticated tracking technology that goes far beyond simple page view counting. It captures detailed, page-type-specific data that Criteo's AI engine uses to build a complete understanding of each visitor's intent and preferences:
- Homepage event — identifies that a visitor has arrived at your store, beginning the tracking session
- Category/Listing event — captures which product categories the visitor is browsing, indicating interest areas
- Product event — sends the specific product ID being viewed, along with price data, to Criteo — this is the primary data point for dynamic ad generation
- Cart event — transmits the contents of the shopping cart with product IDs and quantities
- Conversion event — fires on order confirmation with:
- Complete list of purchased product IDs
- Price per item
- Quantity per item
- Total order value
- Unique transaction ID for deduplication
This granular, product-level data is what makes Criteo's retargeting so effective. The engine doesn't just know someone visited your store — it knows exactly which products they looked at, what they added to cart, and what they ultimately bought. This enables hyper-personalized ad creative that consistently outperforms generic retargeting.
Criteo's AI Engine at Work
What happens after the OneTag sends data to Criteo is where the magic happens:
- User identification — Criteo's identity graph matches your store visitors across devices and browsers using deterministic and probabilistic methods
- Intent prediction — machine learning models analyze browsing patterns to predict purchase probability for each user
- Dynamic creative optimization (DCO) — Criteo's engine generates thousands of ad variations, testing layouts, product combinations, and messaging in real time
- Bid optimization — each ad impression is evaluated individually, with bids calculated based on predicted conversion value
- Product recommendations — beyond showing viewed products, Criteo's engine adds AI-recommended complementary items to increase average order value
All of this runs automatically. Once the OneTag is installed and sending data, Criteo's engine handles everything: ad creation, placement, bidding, and optimization. Your job is simply to ensure the data pipeline works — which is exactly what this module guarantees.
Proven E-commerce Performance
Criteo publishes transparent performance benchmarks that consistently demonstrate its effectiveness:
- Average 13x ROAS across all advertisers
- Up to 60% of retargeted users return to complete a purchase
- Dynamic ads generate 2x the click-through rate of static retargeting
- Cross-device identification captures conversions that cookie-only tracking misses
These results come from Criteo's unique position in the market: no other platform processes as much e-commerce transaction data, which means no other platform's AI has as much learning data to optimize from. Your store's conversion data joins this massive dataset, improving both your campaigns and the broader network.
Setup and Configuration
- Contact Criteo to create an advertiser account and receive your Partner/Account ID
- Install this module on your PrestaShop store
- Enter your Criteo Account ID in the module configuration
- Save — the OneTag deploys immediately across all pages with proper event tracking
- Criteo's team will verify the integration and activate your campaigns
The module handles all technical implementation. Product IDs, prices, cart contents, and transaction details are automatically extracted from your PrestaShop store and formatted for Criteo's API. No manual mapping or data feed configuration is required.
Technical Implementation
- Criteo OneTag (
criteo_q) loaded asynchronously with zero render-blocking impact - Page-type detection automatically maps PrestaShop pages to Criteo event types (homepage, listing, product, cart, transaction)
- Product IDs passed as arrays matching your product feed format for dynamic creative generation
- Cart and transaction events include full item-level detail: product ID, price, and quantity
- Email hashing support for enhanced user matching (SHA-256, MD5)
- Compatible with all PrestaShop themes, checkout modules, and payment gateways
- Multistore support with per-shop Account ID configuration
Why is this module unique?
- Full Criteo OneTag event schema — all five page-type events implemented (homepage, listing, product, cart, transaction), not just basic page views
- Product-level data on cart and conversion events — Criteo receives individual product IDs, prices, and quantities for granular attribution and dynamic ad generation
- Automatic page-type detection — the module identifies whether the visitor is on a homepage, category page, product page, cart, or confirmation page without manual configuration
- Transaction-level deduplication prevents double-counted conversions
- Verified across PrestaShop 1.7, 8.x, and 9.x — Criteo integration works consistently across all supported versions
Use Cases
- Large product catalogs — Criteo excels with catalogs of 100+ products, where dynamic ads can show each visitor a personalized product selection
- High-traffic stores — the more visitor data you send, the smarter Criteo's AI becomes — stores with 10,000+ monthly visitors see the best results
- Multi-category retailers — Criteo's product recommendations cross-sell across categories, increasing average order value
- International e-commerce — Criteo's global network covers 100+ countries, with localized publisher inventory in each market
- Maximizing retargeting ROI — if you're currently running basic retargeting with limited results, Criteo's AI-driven approach typically delivers significant improvement
