Codes
Your category codes for edge — the unconscious athlete instinct is "I'll know what others don't." Your homepage hits this strongly through Seiler's authority, lab-grade language, the "2.4× more effective" benefit, and the Pauline Ferrand-Prévot proof. The H1 is the weakest moment — "Individualize your Training with Breathing Data" reads as HR-language in a category that codes for competitive edge. Your supporting H2s — "Don't Guess. Measure your Progress." and "Stay in the Zone." — are closer to the code.
Context
Endurance athletes don't impulse-buy $299+ wearables. They research for two to four weeks. Your homepage meets them with substance — Seiler, the pros, the press, transparent pricing tiers, threshold education. Phase alignment is high. The one moment you don't address is what their mind goes to around day 11: "how is this better than my Garmin?" Name the comparison directly and the buying window closes faster.
Clarity
Comprehension thins from surface to deep — the paradigm shift doesn't land.
Surface comprehension reads clear — most personas grasped "breathing sensor that helps me train better." Working comprehension drops to partial, and deep comprehension (the threshold-replaces-lactate paradigm shift) reads low. The H1 "Individualize your Training with Breathing Data" describes what the product does without telling the athlete why they'd care. Front-load the outcome — "Train at your true thresholds. Beat your last race." — and the working layer moves from partial toward clear.
Yieldpage scores your homepage against the 9-element Message Market Fit framework. Codes are inferred via pattern matching against a category library of competitor homepages. Comprehension is read by AI personas modeled on your buyer profile, following the surface/working/deep layered test from the MMF book. The free tier covers the unconscious layer — the three pillars of how your page lands before words form. Per-element scoring is qualitative on a 1–5 scale, banded as Filtered (0–7), Approaching (8–10), On-code (11–13), Signaling (14–15).
