Recommendations Not Working

Recommendations Not Showing on Product Pages

Check 1: Plan requirement
Cross-sell, upsell, and bundles require Enterprise Plus or higher. Check your current plan under Pricing.

Check 2: Theme block added?
The Recommendations theme block must be added to your product page template:

Go to Shopify Theme Editor

Open the product page template

Look for the FitmentPro Recommendations block

If missing, add it from the available blocks

Check 3: Recommendations computed?
Recommendations don't generate automatically. Go to Recommendations and click Rebuild Recommendations.

Check 4: Product has fitment data?
Recommendations require fitment rules on the product. Products without vehicle compatibility data won't have recommendations.

Bundle Builder Not Generating Bundles

Ensure you have bundle templates defined (or enable Auto Bundles in TecDoc pipeline)
Products must be categorized into tiers for the bundle algorithm to group them
At least 2 products must fit the same vehicle for a bundle to be created

Cross-Sell Shows Irrelevant Products

Cross-sell uses vehicle overlap as the primary signal. If results seem irrelevant:

Check that fitment rules are accurate on both products

Rebuild recommendations after updating fitment data

Products with very broad fitment (many vehicles) may produce noisy recommendations

Garage Feed Not Personalizing

The customer must have saved at least one vehicle in My Garage
My Garage uses browser localStorage — it doesn't persist across devices
Ensure the My Garage theme block is active on your storefront
