## Data

- UK SEO Retainer Price Index. 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). 30 of the 36 named sources that could be read published a usable figure; 5 published none and are recorded as not published, never filled in; 6 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 GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 357 candidate sentence(s) were refused by a reviewer with the reason recorded. Derivation as chartered: the median, quartiles and full range of the monthly retainer band each UK provider publishes, per region and per business-size row it publishes for; the count and share of providers publishing a BAND versus a RATE CARD versus nothing at all; the movement of each provider's own band between reads, and the year-on-year rise the market states about itself (15-30% since 2024 on one publisher's reading, 12-18% since 2023 on another) measured against our own dated snapshots rather than repeated
