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.
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.
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.
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.
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.
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.
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.

Architecture, Interior Design & Home Improvement BS: DIY Extra (www.diy-extra.co.uk)
DIY Extra is a high-substance, low-ego technical manual that suffers from a lack of formal identity. It provides genuine value through granular detail but fails to prove why a user should trust these specific ‘experts’ over any other anonymous DIY source.
Implement Person schema for all guide authors to link technical claims to verifiable human expertise. Replace native reviews with verified third-party widgets from platforms like Trustpilot or Google to eliminate the trust theatre penalty. Add outbound links to professional building regulations or material manufacturers to provide external validation for technical specs. Include ‘About Us’ content that identifies the brand’s history and professional qualifications.
The site is a perfect match for the Home Improvement sector, specifically functioning as a content-heavy resource for DIY projects. It avoids the service-based jargon of Architecture and Interior Design, focusing strictly on technical instruction and material specifications.
“The score of 31 is driven primarily by the Trust and Proof (15) and Identity and Authority (8) pillars. While the Information Density and Semantic Coherence are nearly perfect (minimal BS), the lack of verified authorship and external proof paths prevents the site from achieving a minimal BS rating.”
This training module utilizes a snapshot of public data from DIY Extra, captured on May 21, 2026, to demonstrate how machine logic evaluates different types of business narratives.
Purpose: This data is presented under “Fair Use” / “Educational Exception” for the purpose of forensic semantic analysis, allowing users to compare human intuition against machine-generated evaluations.
