Predictive grid ranking for DTC storefronts

Cartlyzer scores every visitor-product pair in your active session and reorders collection pages in real time. It does one thing, precisely.

  • Live reranking per session, not batch schedule
  • Conversion-probability score on every PDP
  • Business rules layer that runs on top of AI ranking

Capabilities

Three capabilities that work together

Real-time collection page reranking

Every time a visitor loads or scrolls a collection page, Cartlyzer fires an API call with live session signals: product views, hover events, scroll depth, and cart history. The response reorders the grid within 200ms, before the next render cycle.

  • Works on Shopify collection pages, WooCommerce shop archives, and headless storefronts via API
  • No page reload required: grid reorder uses client-side DOM injection
  • Rank changes flagged with an orange indicator you can inspect in the dashboard

Conversion-probability PDP scoring

Every product detail page gets a live conversion-probability score for the current visitor's session. If a PDP is hemorrhaging sessions, you know before the weekly analytics report. Act on signal, not hindsight.

  • Score updates in real time as the session progresses
  • Dashboard view shows score distribution across your full catalog
  • Low-scoring PDPs surface automatically in your weekly digest

Merchandising rules layered on AI ranking

Your AI ranking is the base. Your rules are the override. Pin new arrivals to the top, exclude SKUs below margin threshold, force clearance items into the first row. Rules execute after ranking, so you never lose conversion intelligence to manual overrides.

  • Rules configured in the Cartlyzer dashboard with no code required
  • Rule priority is explicit and auditable: no hidden interactions
  • A/B test rules vs AI-only to measure rule impact on revenue per session

Architecture

How signals become ranked grids

A lightweight JS tag streams behavioral events. The Cartlyzer inference layer scores per-session conversion probability. Your storefront gets back a ranked product ID array, ready to render.

FAQ

Product questions

No. Cartlyzer runs alongside your theme via a lightweight JS tag and API integration. Your theme renders the grid; Cartlyzer tells it what order to use. No theme code modification required for Shopify Plus.
The tag collects behavioral session signals: page views, hover events (element and duration), scroll depth, add-to-cart events, and collection page navigation. No personal identifiers are collected or stored at the session level. Full data handling details are in our Privacy Policy.
Median API response time is under 200ms at the 95th percentile for stores up to 500,000 monthly sessions. Our infrastructure is deployed in multiple AWS regions for low-latency responses regardless of your customers' geography.
Yes. The merchandising rules layer runs after the AI base ranking and takes explicit precedence. You can pin specific SKUs to the top, exclude low-margin items from reranking, force clearance to the first row, and set collection-level exceptions. Rules are configured in the dashboard, no code required.
Revenue per session on collection pages is the primary metric Cartlyzer tracks. We do not optimize for conversion rate in isolation because that metric can be gamed by surfacing only the easiest conversions. Revenue per session captures both conversion and order value together.
SOC 2 Type II is on our security roadmap for later in 2026. Currently we operate with production-ready infrastructure controls including least-privilege access, TLS in transit, encrypted storage at rest, and scheduled third-party penetration testing. Contact us for our security overview document.
