Case study: Pearle Opticiens achieves 29% increase in orders with Products AI feed optimisation
Challenge: Boost e-commerce sales
Pearle Opticiens’s performance marketing team faced the challenge of increasing E-commerce sales. Their goal was to improve Google Shopping visibility and revenues while automating and optimising feed-based ads in multiple languages (Dutch and French), keeping control over the information communicated to consumers and without adding internal workload.
Approach and Implementation: Testing AI to optimise a high-impact product cluster
To enhance their Google Shopping product feed and drive both visibility and sales, Pearle Opticiens’ team (already using Producthero CSS to benefit from an additional 20% margin on CPC) implemented Products AI to refine product titles and descriptions.
The team conducted a focused pilot on a cluster of 30 products (primarily contact lenses) to minimise the impact of seasonality and accurately measure the effect of AI-driven content improvements. Performance was tracked through a before-and-after comparison of key metrics.
To maintain brand consistency and ensure high-quality output, Pearle Opticians customised the AI with strict prompt guidelines:
- Titles: Retain product name and code; add compelling details; max 70 characters.
- Descriptions: Include key product specifications; max 180 characters.
Results: Substantial growth in orders and revenue
Within just three weeks (May 12 – June 1, 2025), compared to the previous three-week period (April 21, 2025 – May 11, 2025), Pearle Opticiens achieved outstanding results:
- +53% revenue from the optimised product cluster
- +29% increase in total orders
- +7% higher click-through rate (CTR) for enriched titles
These results demonstrate the significant impact AI-driven feed optimisation can have on e-commerce performance, while simplifying the challenges of managing multilingual campaigns.
“By using Products AI to automatically optimise product titles, we achieved a 29% lift in orders and a 7% increase in CTR compared to the previous period. This test clearly shows the power of AI-driven optimisation in improving product visibility and engagement.” Andrea Amadeo, Performance Marketing Supervisor, EssilorLuxottica
Next steps: Expanding AI-driven optimisations
Building on the outstanding results achieved, Pearle Opticiens’s natural next move is to scale AI-powered product feed optimisation across a broader range of product categories.
