Partauto is a French e-commerce retailer specialising in affordable OEM and aftermarket car parts. When the company partnered with WeAdU in 2019, its Google Ads activity was limited to a handful of brand-keyword campaigns—efficient at capturing existing demand but ineffective for growth. The brief to WeAdU was clear: unlock scale in non-brand search while maintaining at least a 10× return on ad spend.

Key Challenges

‍

80 %+ of sales came from branded queries, limiting reach.
Increasing spend on brand terms drove diminishing returns.
Non-brand clicks were expensive and conversion-shy without a data-driven structure.

Notre approche

‍

Phase	What We Changed	Why It Mattered
Foundations (2019-20)	Re-architected campaigns, deep negative-keyword cleanse, first non-brand test.	Built a clean base and proved non-brand could be profitable.
Performance Lift (2020-21)	Smart Bidding, granular Shopping segmentation, feed hygiene.	ROAS rose to 1.5 × the target while acquisition costs fell.
Scaling Era (2022-25)	Product-feed overhaul, Performance Max launch, stepwise budget increases.	Conversions tripled and CPA nearly halved without sacrificing ROAS.
