## Citation surfaces (which UK e-commerce pages get cited)

- **Product detail pages with rich Product schema** — high citation when schema is populated; low without.
- **Category / collection pages with editorial layer** — medium-high; thin grids cite poorly.
- **Review and comparison pages** ("best X UK", "X vs Y") — highest citation across ChatGPT Search, Perplexity, Gemini AI Overviews.
- **Buyer-guide pages** (long-form editorial) — medium-high; strongest for "how to choose" queries.
- **Bare product pages** (no schema, no reviews) — low.
- **Marketing landing pages** — low; engines prefer factual structure.

## UK e-commerce structural signals

- **Product schema with sterling Offer** — Offer.price in GBP, Offer.priceCurrency=GBP, Offer.availability populated, AggregateRating where genuine, Brand populated.
- **Sterling pricing rendered in HTML** — not client-side currency-switched after page load.
- **UK shipping + returns disclosure** — UK delivery times, UK returns policy, sterling shipping costs visible; structured shipping/return policy data where supported.
- **TLD + entity clarity** — .co.uk / .uk reads as UK-anchored; .com sites need hreflang + country-explicit Organization schema.
- **Reachability for AI crawlers** — GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Googlebot allowed in robots.txt; sub-300ms TTFB.

## Methodology operators can run

Pick 10 to 30 shopping-intent queries (mix product-research, comparison, buyer-guide intents). Run weekly across ChatGPT, Claude, Perplexity, Gemini. Per-query, per-engine, record whether your domain appears in cited sources. Output: per-engine citation rate time series. The discipline is the cadence; absolute citation count matters less than per-query trend.

## What is honestly unknown

No vendor publishes a per-vertical citation contract. Specific claims like "Perplexity prefers UK e-commerce with X" or "ChatGPT cites UK e-commerce at rate Y" are inference from observable output, not vendor-stated fact.
