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.

Real Estate, Property & Lettings BS: Century 21 (www.century21.com)
This is a digital ghost ship; a high-authority brand name sitting atop a hollow digital structure that provides no substance. The forensic evidence proves a total failure to deliver information, leaving the brand name to do all the heavy lifting without supporting proof.
Immediate resolution of the technical crawl or ‘loading’ state is required to present actual service content. Implement comprehensive Organization and LocalBusiness schema to anchor the brand’s identity in structured data with sameAs links to official social profiles. Populate the site with specific, verifiable evidence such as recent sale prices, named team members with professional bios, and industry-standard certifications. Replace empty placeholders with a transparent fee structure and clear links to relevant property redress schemes to reduce the BS score.
The forensic data identifies the entity as Century 21 within the real estate and property industry, although the provided crawl data is critically insufficient. The disconnect between the global brand’s expected professional presence and the actual ‘loading’ state suggest a total failure of digital signaling.
“The BS score of 70 is driven by the absolute failure in Information Density and Semantic Coherence pillars due to the 'insufficient' data status. While the site avoids 'Trust Theatre' penalties for fake reviews, the complete absence of identity and authority markers results in a high score for hot air and lack of proof.”
