Skincare Performance Max Case Study: 8.7x ROAS With Better Creative Signals

A confidential skincare brand had strong products, but its paid search system was underfed. Performance Max was spending, but the campaigns lacked the creative assets, audience signals, and control structure needed to produce reliable ecommerce growth.

This case study shows how Powerhouse Media improved campaign quality by rebuilding the system behind the ads.

The Challenge

The brand had organic traction and product-market fit, but its Google Ads account was not translating that demand into profitable growth. Performance Max campaigns were receiving weak creative inputs, audience signals were too thin, and the brand had no clean Shopping Standard campaign to benchmark against PMax performance.

What We Did

We approached the account as an input-quality problem. Performance Max can only optimize against the assets, data, feed, and conversion events it receives.

• Added high-quality image and video assets across campaign formats.
• Built custom audience signals from customer data and product interest patterns.
• Created a Shopping Standard campaign as a control and protection layer.
• Gradually tightened CPA targets as conversion volume matured.
• Reviewed product group performance to prioritize the SKUs with better margin and conversion potential.

The Result

In three months, the account generated $3.9M in conversion value from $448K in spend, producing an 8.7x ROAS.

• 24,300 purchases
• $18.40 CPA
• $1.06 average CPC
• 10.01 ROAS from the leading all-products PMax campaign

Why It Worked

The improvement came from giving Google Ads better information. Better creative assets improved placement performance. Better audience signals helped the algorithm learn faster. The Shopping control campaign gave the team a clearer benchmark instead of relying on a black-box view of results.

Frequently Asked Questions

Why does creative quality matter in Performance Max?

Performance Max serves across multiple placements, so weak or incomplete creative assets limit where the campaign can perform well.

Should ecommerce brands still use Standard Shopping?

Often yes. Standard Shopping can act as a control layer and provide clearer visibility into product and query performance.

Can Performance Max work without strong first-party data?

It can run, but stronger audience signals and conversion history usually improve learning quality and campaign stability.

What should skincare brands measure?

Measure ROAS, CPA, repeat purchase potential, product margin, and new customer acquisition quality rather than clicks alone.
