How we measured this
Google Places API (New) Text Search, up to 3 pages (60 results max) per (niche, city) query — matching the product's own pagination depth (apps/api/src/routes/agent.ts's SEARCH_MAX_PER_QUERY) — plus a live homepage fetch (browser-UA retry on bot blocks, up to 400 KB) checking for a mobile viewport meta tag. Facebook/Instagram/etc. listed as 'website' counted as no real site, matching the product's own definition. Bot-blocked sites are unverifiable and excluded from the percentages.
