The challenge

Scale revenue without chasing cheap clicks.

Growing Google Ads spend is easy. Growing it while keeping purchase quality and return on ad spend intact is the hard part. We ran two Performance Max approaches side by side, then fed Google better data so it could find higher-value buyers.

What we did
  1. 01

    Performance Max, feed only

    A shopping-focused campaign driven by an optimized product feed, putting frames in front of people already searching for eyewear.

  2. 02

    Full Performance Max

    Text, image and video assets reaching shoppers across Search, Shopping, YouTube, Display, Discover and Gmail.

  3. 03

    Clean purchase data

    Cleaned up conversion tracking so Google learned which customers made quality purchases and scaled toward them.

  4. 04

    Protected the best sellers

    Top-selling frames got their own campaign and dedicated budget, while the rest of the catalog was tested separately.

  5. 05

    Tuned target ROAS every month

    Loosened it to open up volume when demand was there, tightened it to protect efficiency when it wasn't.

The results

Sales up, efficiency up, month after month.

Outside a product-driven dip in July, ROAS held at 2.5 or higher from May onward while gross sales grew.

Sales and spend indexed to April = 100. ROAS is gross Google sales before returns.

Setback and rebound

In July, limited product availability on the website cut gross sales 39% and ROAS slipped to 1.60. The dip came from the site, not the ads. Because the data foundation and product segmentation were solid, nothing needed rebuilding. We adjusted target ROAS, and once the product issue was fixed, August sales rose 58% while spend dropped 16%, pushing ROAS to 3.03, the best of the period.

Key takeaways

Performance Max is only as smart as the signals it gets.

  • Data quality drives scaleAccurate purchase data let it scale toward better buyers.
  • Protect your winnersSegmenting best sellers kept them funded and performing.
  • tROAS is a dial, not a settingRegular adjustments kept spend and volume in balance.
  • A strong foundation survives a bad monthThe July dip didn't break the account, and August proved it.
