Analyze the raw signals below. How would a machine score this business’s credibility?

Here are the exact signals captured from up to six pages of the site — the same raw inputs the evaluation engine analyzed. They are grouped by signal type so you can weigh each the way the machine does.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

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.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

https://feltham-plumber-london.business.site 📍 Industry: Home Services (Plumbing, Roofing, HVAC, Electrical)
48 BS / 100

The site is a digital ghost; it signals a localized professional service through its URL but provides a 404 vacuum in place of substance. It is not ‘BS’ in the sense of inflated marketing, but rather in the sense of a complete failure to exist. The distance between its signal as a local tradesman and its reality as a broken server link is absolute.

First, resolve the server configuration issues to eliminate the 404 error and restore the homepage. Second, populate the site with high-density information including specific plumbing services and a Gas Safe registration number. Third, implement LocalBusiness schema and Person schema for the lead plumber to bridge the authority gap. Finally, add verifiable proof points such as links to a Checkatrade profile or photos of completed work in Feltham.

The domain name and URL suggest a classification within the Home Services (Plumbing) sector in the London area. However, the actual content of the page is a 404 error, which provides zero confirmation of trade expertise, services, or regional coverage.

“The score of 48 is primarily driven by the extreme Semantic Drift (13 points) and Information Density failure (15 points). While the site avoids typical 'marketing fluff' penalties because there is no text to inflate, it is heavily penalized for Technical Credibility Gaps (10 points) and the total absence of specificity (5 points) and proof paths (5 points). This score reflects a business that is signaling an identity it does not technically support.”
