Auto Parts e-commerce

We partnered with an online auto parts store whose Meta account was delivering sales but disappointing returns. After rebuilding the structure, activating catalog campaigns, and tightening creative testing, the brand increased summer ROAS from 33.5x to 40x and unlocked more than €124K in additional revenue over two years.

Brand and challenge

The client is an e‑commerce store selling auto parts online, with summer being a key revenue season. Before the collaboration, the Meta account suffered from chaotic ad structures, too many creatives stuffed into single ad sets, and almost no ability to scale what worked.

There were no automated catalog campaigns to bring in new buyers or retarget existing visitors. Despite seeing some sales, the owner was unhappy with the overall return on ad spend and felt the account was leaving substantial money on the table.

Strategy

The primary objective was clear, maximize profitable revenue during summer while building a structure that could scale safely year over year. Key metrics included ROAS, additional revenue and sales volume, CPA, AOV, and budget efficiency.

The strategy focused on full structural overhaul plus automation. Catalog campaigns, segmented by product categories and brands, would handle both prospecting and retargeting. Creative testing would run under controlled conditions so winners could be identified and scaled quickly. Budget rules were designed to protect spend in weaker periods and push hard during peaks.

Execution

First, the team activated automated catalog campaigns for both new customer acquisition and warm audience retargeting, which allowed the system to dynamically show the most relevant products.

Next, the campaigns were restructured around product categories and specific brands, so each ad set spoke to a tightly defined context and audience. The number of creatives per ad group was cut down, and ads were tested under equal conditions, making it easy for Meta to find and favor true winners.

Finally, dynamic budget control was introduced. Spend stayed conservative when performance signaled lower intent, then scaled up aggressively when demand and ROAS spiked, capturing maximum traffic without wasting budget.

Results

Comparing summer 2023 to summer 2025, ROAS increased from 33.5x to 40x an uplift of 19.4 percent in already strong returns. The new structure generated an extra €124,672.06 in revenue and 333 additional sales, while keeping cost per acquisition at a highly efficient €7.42. Average order value rose from €262.37 to €297.00, adding €34.63 per order on average.

All of this was achieved with only €2,169.62 more budget invested, showing that intelligent restructuring and scaling, not just higher spend, drove the performance gains.
