Information Density — The Lens
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

The site exhibits a moderate fluff ratio with headings like [H1] Reliable plumbers and [H2] Quality heating services providing little differentiation. However, body text contains high-value substance including Gas Safe registration number 539111, Vaillant preferred installer status, and specific 12-month workmanship guarantees. There is significant concept repetition regarding ‘bespoke bathrooms’ and ‘St Helens coverage’ across all six pages, which artificially inflates character counts without adding new technical data.
Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

🧭 Industry Context — common generic-claim patterns in Home Services (Plumbing, Roofing, HVAC, Electrical) to weigh the text against
Generic Claims:
no job too small, fast and reliable, honest and affordable, your local trusted tradesman, available 24/7, fully qualified and insured…
Red Flags:
gas work offered without visible Gas Safe registration, electrical work without Part P certification, no insurance information, pricing guarantees without site survey, stock photos instead of real work examples, claims all trades with individual practitioner…
Semantic Drift Patterns:
claims specialist but offers every trade under one brand, homepage says Gas Safe but registration not verifiable, claims commercial capability but portfolio is residential only, emergency service claims but no out-of-hours contact mechanism…
Proof Expectations:
Gas Safe registration number (for gas work), NICEIC or NAPIT registration (for electrical work), public liability insurance details, verifiable Checkatrade or TrustMark profile, named completed jobs with customer permission, specific manufacturer accreditations (Worcester, Vaillant)…
