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.
Based on 1850 businesses audited.
Mailjet has 23.1 points less BS than the average for Marketing, SEO & Advertising Agencies.
Marketing, SEO & Advertising Agencies BS: Mailjet (www.mailjet.com)
Mailjet is a rare example of a marketing-facing website that maintains high technical integrity. It effectively bridges the gap between marketing fluff and developer-level substance by grounding every benefit in a verifiable technical protocol or regulatory certification.
To achieve a minimal BS score, Mailjet should replace the subjective H1 adjective Best with a quantifiable metric, such as a verified deliverability percentage. They should also link the review_count directly to the third-party platforms (G2, Capterra) to eliminate the trust_theatre_flag. Finally, adding Person schema for key technical architects would close the minor authority gap.
The site is classified under Marketing, SEO & Advertising Agencies, but it functions as a Software as a Service (SaaS) platform. The content confirms a focus on marketing automation and email delivery, though it serves both developers and marketing professionals rather than being a service agency.
“The score of 22 is driven primarily by strong performance in Information Density and Semantic Coherence. The site avoided 20 points of potential penalties by having perfect alignment between its H1 promises and sub-page technical documentation. The remaining points are derived from subjective industry jargon (Best, Beautiful) and the inherent anonymity of the product-led schema.”
