Primary KPI: Average order value
Secondary KPIs: Items per order, Add-to-cart from the cart cross-sell, Cart-to-checkout rate
I-003 · Product cards on collection pages show no review stars

Secondary KPIs: view_item events, Add-to-cart rate from PLP-originated sessions, Collection-page bounce rate
I-004 · No sticky Add-to-cart on the long mobile product page
If: If a sticky Add-to-cart bar is present on mobile product pages, more shoppers will add to cart without scrolling back to the buy box.

Secondary KPIs: Scroll depth before add-to-cart, Time-to-add-to-cart, Mobile PDP exit rate
I-005 · Homepage lacks an above-the-fold value proposition and trust bar
If: If the homepage states a clear value proposition and trust signals above the fold, more first-time visitors will continue into a collection.
Primary KPI: Homepage-to-collection click-through for new users
Secondary KPIs: Homepage bounce rate, Scroll depth, New-user PDP view rate
I-013 · Product reviews are shown on the page but not marked up as AggregateRating schema
If: If product pages emit AggregateRating structured data, star ratings will appear in Google results and lift organic click-through to product pages.

Secondary KPIs: Rich-result impressions, Organic product-page entrances, Add-to-cart rate from organic PDP sessions
