## Methodology

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2). 15 of the 27 named sources that could be read published a usable figure; 12 published none and are recorded as not published, never filled in; 1 could not be read (blocked, dead or unreachable) and count nowhere. The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 125 candidate sentence(s) were refused by a reviewer with the reason recorded. The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): price per keyword lookup, computed across every tool that publishes a plan (plan price divided by the lookups, credits or reports the plan allows) beside the free tier's real allowance in searches per day - the two numbers a buyer compares and no vendor states together. Per tool: the billing unit (lookups, credits, seats, flat), the free tier's daily cap, whether clustering and a difficulty score are included or an add-on, the platforms covered (Google, YouTube, Amazon, Etsy, Bing), and the databases and countries the vendor claims. Estate-wide: median price per lookup, the share of tools with a real $0 tier versus a trial, and which tools removed their free tier since the previous read.
