seo-vertical-detect

Given the PageSnapshot, classify the site so the orchestrator can route conditional modules. Read references/routing.md for the signal table.

Method

Score each vertical from observable signals (not guesses):

ecommerce — Product/Offer JSON-LD, cart/checkout/add-to-cart routes or buttons, price + currency elements, og:type=product.
local-business — LocalBusiness JSON-LD, NAP block (name/address/phone), maps embed, opening hours, store-locator.
blog-publisher — Article/BlogPosting JSON-LD, author bylines/author pages, RSS/Atom <link>, dated post archives.
saas — pricing/signup/login routes, SoftwareApplication schema, feature/integration/docs pages.
docs — docs/reference routes, sidebar/version nav, dense code blocks, present llms.txt.
generic — none dominates.

A site can match several; return all that clear the threshold, ranked, plus a primary.

Locales: detect hreflang tags, <html lang>, and locale-prefixed routes (/es/, /fr/). If >1 locale, flag multilingual so M20 (hreflang) activates.
