What is the outcome documented in this case study?

This engagement produced a 703% impression spike on a luxury Judaica brand's Shopify Performance Max campaigns following structural feed and campaign restructure. The impression gain correlated with improved conversion rate on the expanded inventory surface. The engagement was delivered under NDA.

What was the diagnostic finding?

The diagnostic identified product feed fragmentation, missing product attributes weakening PMax signal quality, and campaign structure that prevented PMax from allocating budget to high-intent queries. Fixes targeted feed enrichment, campaign segmentation, and asset completion across the Signal Stack layers.

What is a 703% impression spike and why does it matter?

A 703% impression increase means Google's Performance Max algorithm began surfacing the account's products across surfaces at more than seven times the prior volume. Impression growth of this scale only occurs when PMax signal quality improves sharply, indicating the prior campaign state was signal-starved.

No. The engagement is NDA-protected. The brand is described by category (luxury Judaica) and platform (Shopify) to provide context without entity identification. All Stan Consulting case studies follow the same NDA-safe convention for client confidentiality.

What was the engagement structure?

The engagement began with a Conversion Second Opinion that produced the diagnostic report and prioritized fix list. The Revenue Sprint followed to implement the top three structural fixes identified. Total elapsed time from first client contact to measured impression spike was approximately eight weeks.

The commercial situation

Context

The client operates a luxury Judaica brand on Shopify with an average order value above $400. Primary markets are the United States, Israel, and parts of the European Union. We were engaged to restructure Performance Max after a twelve-month period of declining ROAS despite consistent spend.

The diagnostic

What the review surfaced.

The Conversion Second Opinion identified the following structural issues in the account and surrounding commercial system:

Feed hygiene failures

30% of the active catalog was flagged as disapproved or limited due to GTIN mismatches, missing identifier_exists flags, and title-length truncation that ate product names above 150 characters.

Asset group thematic drift

A single asset group carried 4 product categories. The algorithm optimized for the average, starving the high-margin categories of budget.

Audience signal absence

No customer list seeded. No remarketing list. The algorithm began every auction cold.

Brand cannibalization

Brand search terms were being served through PMax, absorbing 18% of PMax budget without incremental revenue.

The intervention

What the fix list prescribed.

Feed rebuild. Asset group split into four margin-based segments. Customer list and cart-abandoner audiences seeded. Brand negatives applied. Bid strategy migrated from Max Conversion Value to Target ROAS once conversion volume cleared 50/week.

The outcome

Commercial result.

Within eight weeks: a single pillar article that was previously tangential to the campaign architecture began to rank as a Google SGE source. Search impressions on the target query set rose 703%. Conversion volume from the reclaimed brand budget showed a 34% lift in non-brand ROAS over 90 days.

All client identifying details NDA-protected. Metrics represent real engagement outcomes with account identity, product specifics, and geography generalized.

Proof route

Use this proof to check the Shopify revenue path.

This proof points readers toward the next check without expanding the documented outcome.

When to use it

Ad spend, clicks, CPA, or ROAS are not turning into qualified revenue. Money risk: Budget keeps moving while the account, page, offer, or tracking leak stays hidden.

What this proof is useful for

SC checks traffic quality, product page trust, offer friction, cart and checkout behavior, feed signals, and attribution before adding spend.

What it does not claim

It does not guarantee the same outcome, invent a client result, or turn proof into a generic sales claim.

Problem route Read the symptom → Use this when ad spend, clicks, CPA, or ROAS are not turning into qualified revenue.

Diagnostic route Start with the written diagnostic → Use the Conversion Second Opinion when the failing layer is still uncertain.
