Description

User wants to know WHERE in the catalog shopping funnel they're losing shoppers. Keywords: "funnel", "drop-off", "people add to cart but don't buy", "abandoned carts", "why aren't products converting", "checkout drop". Reports the catalog funnel (product view → add to cart → checkout → purchase) per product and account-wide, from cached nightly metrics. For each product and the account it computes the stage-to-stage drop-off RATES and states, as a MEASURED FACT, the stage with the largest drop (e.g. "82% of carts didn't reach checkout"). It does NOT label a drop "severe" or assert a diagnosed cause — it offers COMMON REASONS to check at that stage (creative/feed at view→cart; price/shipping at cart→checkout; payment/checkout friction or pixel firing at checkout→purchase) as guidance, not a verdict. Reads cached nightly product metrics (never calls Meta live). When to use: "Where are shoppers dropping off in my catalog funnel?", "Why am I getting carts but fewer sales?"
