Doubling Online Sales (+125%): How Olivia Garden Scaled to 748% ROAS.
4 out of 5 orders were invisible to Google Analytics due to Safari cookie blocks.
Lines-Up connected server-to-server tracking to the payment gateway, scaling net sales on the exact same budget.
High ad expenses eating 30% of sales because Google was blind to card payments.
Olivia Garden makes world-famous salon hairbrushes. Their official online store ran Google Shopping and Performance Max campaigns, but ad costs ate an unsustainable 30.7% of gross sales:
80% of Card Payments Were Invisible
When customers paid via online banking or Apple Pay, they confirmed payment in their bank app and closed the browser. Because old tracking only counted "Thank You" page loads, 80% of paid orders never reached Google Analytics.
Google Optimized for Useless Phone Taps
Because Google didn't see real card payments, it optimized campaigns for simple clicks on phone numbers. It burned budget finding window-shoppers instead of buyers ready to spend €35+ on premium brushes.
Campaigns Bidding Against Themselves
Search campaigns and Google Shopping were bidding on the exact same brand keywords at the same time, driving up internal click costs unnecessarily.
Losing High-Margin Wholesale Salons
Salons looking to buy 50+ brushes landed on an empty contact page, causing profitable wholesale orders to abandon without purchasing.
Feeding real cash register data to Google Ads instead of useless clicks.
We didn't need to increase the monthly advertising budget. We simply reconnected real bank payment data and grouped campaigns around high-margin products:
Direct Server-to-Server Bank Tracking
We built a direct server connection to the payment gateway. Even if the buyer closes their browser immediately after paying, the server instantly sends the verified order value to Google Ads (99.7% match with cash register).
Training Smart Bidding Only on Real Buyers
We removed phone clicks from ad goals. Once Google was fed real order values, its algorithms automatically prioritized buyers looking for premium thermal brush sets, doubling the average order value (+96.5%).
Restructuring Shopping & Margin Filters
We eliminated keyword overlap and set up Google Shopping feeds to bid higher on high-profit items and lower on low-margin accessories, lifting Shopping orders by +57%.
Wholesale B2B Ordering Funnel
Built a simple wholesale page with instant price lists and wholesale checkout, capturing salon orders directly without manual back-and-forth emails.

"When your ads eat 30% of sales, the problem is rarely the creative or the bid. Almost always, the algorithm is simply flying blind because 30% to 50% of real card checkouts fail to register in standard analytics. The moment you feed Google true bank payment data, the algorithm automatically finds higher-value buyers."
