Our Shopify audit compares your metrics against these benchmarks across 6 key areas:
Shopping Feed Quality
We check if your Shopify Google Channel is properly syncing product data, including sale prices, custom labels, and optimized titles
Performance Max Structure
We analyze your asset group segmentation—are you running one group for 1000 products or properly segmented by margin tier?
Brand vs Non-Brand Split
We calculate what percentage of your 'conversions' are actually branded searches vs true new customer acquisition
Product Performance Distribution
We identify which products are getting 80% of spend but only 20% of conversions (and vice versa)
Conversion Tracking Accuracy
We verify your Shopify purchase tracking is using native Google Ads tags, not GA4 import which underreports by 15-20%
Competitive Positioning
We compare your CPCs and impression share against Shopify stores in your vertical using industry benchmarks
