Section Design Library
Section design — the unit you actually build. Every page is a stack of these bands; each card is one band zoomed in: its job, how many crawled pages carry it, and where on the page it typically sits — all measured. The trinity: Funnel designs (the multi-step play) → Page designs (the stack) → Section designs (the band). Same blocks, three zooms.
The promise, continued. One message, one CTA — everything else waits below the fold.
Objections, answered one at a time. The section where doubt goes to get resolved.
Borrowed authority in one silent row. It argues nothing; it just stands there being recognizable.
The money ask, structured. Tiers anchor each other; the middle one is doing the selling.
The ask, repeated in isolation. No new information — just the door, held open.
The mechanism, tiled. What it does, shown as repeatable units a skimmer can count.
The open-tabs section. An honest grid with conceded rows — a table you win 10–0 reads as rigged.
The consolation ask. Not ready to buy — leave a way to resume the conversation.
Numbers as proof. Adoption counts and outcomes, big enough to be the message.
Other people already decided. Mass (a wall) or depth (one story) — never three polite quotes.
Method: every crawled page is segmented into full-width bands and each band classified into a section archetype by deterministic DOM signals — no LLM, no opinion. Prevalence counts each archetype once per page, across pages crawled all the way to the footer (partial crawls are held back, not guessed). "Typically sits" = the average of the section's position within the page body (0 = top, 1 = bottom). Scoped to the pages we've crawled, not "the web"; auto-updating as the corpus grows.
