As a Feed account Manager, I was responsible for optimizing raw product data into high-quality, channel-ready catalogs for a portfolio of e-commerce clients. I handled both the strategic and technical aspects of product feed management to ensure visibility, compliance, and performance across major acquisition channels.

First point of contact for new client onboarding: audit of the existing catalog structure, identification of gaps or errors, and creation of a tailored action plan.

• Set up and maintenance of product feeds through data aggregators (Channable, Lengow, SmartFeeds), ensuring structured and enriched data ready for activation.

• Technical implementation of feed connections across multiple sales and marketing channels (Google Shopping, Meta, Instagram, affiliate platforms…).

• Daily monitoring and support: feed validation, troubleshooting, and continuous optimization to maintain data quality and compliance with platform requirements.

• Collaboration with Account Managers to create and implement seasonal rules, promotional campaigns, and channel-specific catalog adjustments based on marketing strategy.

• Strategic advisory on product data: improving content quality (titles, images, attributes, categories, GTIN…), segmentation, and prioritization of high-potential SKUs.

• Performance analysis and reporting to guide clients on catalogue improvement and feed efficiency.

This experience gave me a strong foundation in product data structuring, feed automation, cross-channel activation, and collaborative e-commerce strategy — all key to the Product Data Specialist role.
