CatalogScan FAQ foil — where AI shoppers diverge.

Is the score the same for ChatGPT, Perplexity, and Google AI Mode?

Mostly. The 15 floor and ranking-spread signals are the union of what ChatGPT Shopping, Perplexity Shopping, and Google AI Mode read — about 12 catalog and structured-data signals overlap. Three signals diverge: Brand entity matters more for Perplexity, image alt-text matters more for ChatGPT Shopping, and review recency (fresh Review.datePublished / Review schema) matters more for Google AI Mode. The score is the best single number; the per-signal breakdown lets you optimize for whichever agent you care about most.

What does CatalogScan group under Reviews & availability and catalog feed?

CatalogScan's homepage groups three buckets. Catalog feed: GTINs, Google product categories, metafields, structured data, pricing signals — the core identifiers agents use to pick products. Discoverability: sitemap, robots, canonical tags, JSON-LD, Open Graph. Reviews & availability: aggregate ratings, review recency, stock status, shipping windows — the secondary signals that break ties when agents rank. We already score GTIN · AggregateRating in the 70 and present review recency; this foil adds stock status · shipping windows · Google product category on the same ranking-spread scorecard (presentation, not folded into the 70).

How does CatalogScan foil Merchant Center identifier honesty?

Beyond stock status · shipping windows · Google product category (#61), CatalogScan presents three Merchant Center honesty checks on the same ranking-spread scorecard (presentation, not folded into the 70). identifier_exists must be no/false when a product truly has no GTIN · MPN · brand — leaving it unset while UPIs are missing is a common disapproval path. MPN is a manufacturer part number, not a place to park a GTIN-shaped barcode (MPN-as-GTIN). shipping_label is a short rate-group key for Merchant Center shipping settings — not free-shipping copy, dollar amounts, or delivery ETA prose. Distinct from Store Quality shippingDetails (#58) and from GTIN coverage already scored in the 70 (#51 fold-in).

How does CatalogScan foil Merchant Center conversational attributes for AI Mode?

Beyond #65 (product_highlight for AI Mode), CatalogScan presents Merchant Center conversational attributes on the same ranking-spread scorecard (presentation, not folded into the 70). Google says conversational attributes help AI systems and conversational agents understand product nuances across AI-driven surfaces like AI Mode in Search — optional complements to the primary product data spec. We foil question_and_answer (FAQ pairs agents can cite) and popularity_rank (% inventory popularity). product_detail remains complementary — do not duplicate description · product_highlight · product_detail into conversational attributes. Distinct from #65 and Store Quality (#58). Cite GMC answer/17085370.

Foil to CatalogScan-style free scans.

Public free scans (CatalogScan and peers) lead with a Floor-5 check: products.json, Product JSON-LD, sitemap, OG, robots — then ranking-spread (Description · SKU · JSON-LD validity + Brand · Canonical · Offers + GTIN · rating · alt) toward the 15-signal / 0–70 foil, plus Microsoft UCP readiness (return_policy_labels · consumer_message, GoDataFeed Sep14 foil), plus Store Quality adjacency (shipping · returns · site experience) — then a shareable /scorecard/{domain} viral badge, a homepage Recently scanned strip, and a public /leaderboard (top-100 foil). We ship that same floor + ranking-spread + UCP + Store Quality for free (no login), permanent scorecards, the viral loop, plus full readiness and compare-two-stores, with top signals and top fixes, no email gate.

The paid wedge here is different. Feed Intelligence scores the Google catalogue after Merchant Center OAuth: coverage gaps, disapprovals under live ads, offer-ID rewrites between snapshots. A public scanner cannot see that half. Catalog monitoring is $49/mo with a 14-day trial inside Shopify.
