Read the denominators
Citation share counts answer-linked annotations, including repeated links. Answers citing a domain deduplicate it within each answer. The full denominator is 2,400 completed answers per provider; stratum denominators are 1,000, 600, 400 and 400. Ties are ordered alphabetically. A domain absent from the collected citations has no observed rank.
Curtis reviewed the selected top 100 of 4,631 collection domains; the other 4,531 remain provisional. Category comparisons use the reviewed subset and pool all other domains as unreviewed. This purposive sample favors frequently cited domains and cannot establish category preferences across the web. Labels describe source type, not accuracy, peer review or authorship of every hosted page. Company blogs are company sources; shared hosting follows the frozen domain aggregation rule. Public metadata is cached for all 239 unique cited YouTube video IDs; views are later snapshots. Consumer apps can behave differently. No traffic, quality, source support or video-watching claim follows from a citation.
