Wix's native tracking often misses enhanced conversions, cart data, and cross-device attribution. You're flying blind on what's actually working.
Example: Campaign showing 2x ROAS but actual tracked revenue 40% lower
Wix's Google Shopping app works but lacks advanced features like custom labels, supplemental feeds, and automatic inventory sync for all variants.
Example: Products disapproved due to variant sync issues
Wix checkout has fewer payment options and less conversion optimization compared to Shopify. High-intent traffic drops off at payment.
Example: 32% checkout abandonment vs 24% industry average
With a single asset group, Google optimizes for aggregate ROAS by heavily favoring your top 5-10 products. The rest of your catalog gets almost no impressions. Worse, low-margin products drag down profitability while appearing successful in aggregate.
Fix: Segment products by performance tier: Winners (scale), Potentials (test), Underperformers (cut or fix). Create separate asset groups for each.
PMax claims credit for brand searches that would've cost $0.30 through a dedicated brand campaign. Without exclusions, you're paying 3-5x more for customers already looking for you.
Fix: Add brand exclusions to PMax and run a separate Brand Search campaign with exact match keywords.
Missing GTINs, generic titles, no custom labels, and missing sale prices hurt your Shopping ad performance. Variant sync failures
Fix: Use Wix's Google Shopping integration but verify sync regularly
Your 5x ROAS might look great until you realize 70% of sales are repeat customers who would've bought anyway. You're paying to acquire customers you already have.
Fix: Segment reporting by new vs returning customers. Set up customer match lists and analyze true CAC.
