• Unbounce Conversion Benchmark Report - landing page data across industries; used here for the shape of variation between industries, not as a target for any store.
• CXL - practitioner research and testing method writing.

• Chrome UX Report documentation - real-user performance data.
• Shopify Help Center, WooCommerce Docs and WordPress Documentation - platform mechanics for the platform benches.
