SEO for plumbers, set around the towns you cover

Every provider below was read on its own page through our fetch box, and the row says what that page published on the day we read it. 28 of 50 publish a figure; the rest are listed too, because how many will not quote a number is the most useful thing about this market. Nothing here is a quote for your job: it is what other people advertise.

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). 11 of the 27 named sources that could be read published a usable figure; 16 published none and are recorded as not published, never filled in; 4 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; 252 candidate sentence(s) were refused by a reviewer with the reason recorded. Derivation as chartered: the median, minimum and maximum PUBLISHED monthly retainer across every GB agency that publishes one, split by tier, by whether a website is bundled in, by contract length and by trade specialism; the share of agencies publishing a rate at all against those quoting only after an audit; and the published entry floor against the published 'do not go below' figure that the same agencies write - which is a contradiction this market states openly and nobody tabulates.
