# MK-173｜Diagnose Browsing Without Adding to Cart

For a regular chat, upload `packs/mk-173.md`; it includes the shared rules, this method, and required references

## Purpose

This Skill delivers: **Possible causes to verify, including insufficient information and demand mismatch**

Event groups do not necessarily represent the same people dropping off at each stage; verify counting and attribution across data sources

## Required Inputs


Available raw records: same-product views, cart adds and orders, page versions, variant availability, and customer questions

## Method Steps

1. Join views, cart adds, orders, and page versions for the same product and observation period. First inspect required variant availability and the cart button; aggregate events do not locate psychological causes
2. Resolve unavailable required variants or broken interactions first. If customer remarks identify missing size, compatibility, or usage information, add the supported product answer
3. Use matching genuine evidence when remarks question authenticity, performance, or support. For someone who intends to buy later, propose a reminder only when a real deadline or inventory fact supports it
4. Without distinguishing records, report browsing without cart adds with the cause unresolved. Inspect an actual page interaction or one customer question rather than simultaneously testing discounts, testimonials, and countdowns
5. Newly found cart adds or purchases remove the record from this group and trigger tracking reconciliation. No response after adding information does not establish distrust; use new remarks or a comparable single-variable result for the next choice

## Calculation and Interpretation

Same-group cart-add rate = valid visitors who added to cart / valid product viewers with a complete observation window. If events cannot be joined by person, report them separately. Deliver the concrete gap and next record that would change the action

Check example (hypothetical): a customer reads the size chart without adding to cart; the cause is unresolved. Inventory then shows the required size L is unavailable; offer a restock notification or suitable substitute rather than adding countdown copy
