Cross-Brand Product Comparison Feature for Amazon Shoppers
A browser-aware compare feature for Amazon shoppers who juggle tabs when buying electronics, footwear, or appliances
✳The problem they went after
Buying a high-consideration item on Amazon means opening a tab per product and holding price, ratings, delivery speed and specs in your head. Amazon's existing comparison tables work inconsistently and only line up products from the same brand, so anyone cross-shopping brands ends up doing the comparison manually across browser tabs.
✳What they actually did
The proposal is Compare Open Tabs: detect the Amazon product pages already open in the browser, then build a side-by-side table on demand. One consistent format covering price, delivery speed, customer ratings, seller ratings, key features, specifications and return policy, with add-to-cart straight from the comparison view. No setup, nothing to learn. Measurement is spelled out too: search-to-purchase conversion among users who compare is primary, click-through on the compare button and time from search to cart are secondary, cart abandonment and page load act as guardrails.
✳What you can take from it
Worth stealing
- Compare Open Tabs reads product pages already open in the browser
- One table: price, delivery, ratings, specs, return policy
- Add to cart directly from the comparison view
- Guardrails on cart abandonment and page load performance

Designing a feature that rides on a workaround users already have
The transferable bitBuilding on a behaviour users already have beats asking for a new one. Tab-juggling is the existing workaround, so the feature carries no onboarding cost. The metric stack is also worth studying: one conversion metric that proves value, two behavioural metrics that explain it, and guardrails that catch overload and slow pages.
