How is this ranking calculated?
Position is computed from verified data, not opinion: each tool scores one point for every feature on the category's comparison axis that its vendor publicly documents. Features marked partial or not verified score nothing. Ties are broken by the lowest entry price, and only when both amounts are published in the same currency and billing period; when they are not comparable, the tie is broken alphabetically. Sponsorship is labelled explicitly and never alters the order.
Which crawler should you use to audit a large site?
A technical crawler walks the site the way a search engine would and exposes what badly served HTML hides: redirect chains, contradictory canonicals, content that only exists after JavaScript runs. Here the variable that drives price is URL volume.
