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.

Social Networks, Communities & Forums BS: StumbleUpon (stumbleupon.com)
StumbleUpon currently exists as a skeletal landing page suffering from a critical identity crisis and a direct contradiction in its monetization claims. The total lack of technical hierarchy and structured data suggests a neglected property rather than a functioning social network. It scores high on the BS scale because it asks for user and advertiser trust while providing zero substance, zero proof, and conflicting signals.
Immediately resolve the contradiction between the ‘No ads’ claim and the ‘advertising services’ description. Implement a proper HTML heading hierarchy (H1, H2, H3) to define the service’s core features and benefits. Add Organization schema and Person schema for leadership to establish technical authority. Provide links to actual case studies or a transparency report to substantiate the ‘millions of sources’ claim.
The site fits the Social Networks and Communities category as it explicitly mentions online communities, social networking services, and content sharing. However, the content is extremely sparse and lacks the active engagement signals expected in this industry.
“The score of 76 is driven primarily by Information Density and Semantic Coherence. The total lack of headings and the direct conflict between claiming to be 'ad-free' while selling 'advertising services' are massive red flags. The technical void (no schema or metadata) further reinforces the gap between the brand's legacy and its current substance.”
