CTA

Copy, size, verb, cost-feel — does the primary CTA earn the click?

Mobile web

62Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. About us CTA — Primary action is a small outlined button labeled "About us →" — an informational link, not a conversion action, and it sits at the very bottom edge of the fold.
  2. Body paragraph — Six lines of dense KV-cache copy push the CTA to the fold's bottom edge; the value statement should compress to two or three lines on a phone.

Information hierarchy

68Fair

Does the design help or inhibit what the page is trying to say?

Information hierarchy annotations on the desktop capture123
  1. About us hero CTA — The only in-content action points to a bio page, not the conversion; 'Book a demo' lives isolated in the top-right corner.
  2. Diverging arrows diagram — Arrows fan out toward OpenAI/Anthropic logos with no labels, so the visual explains routing worse than one caption would.
  3. Nav link row — Five same-weight links, including 'Privacy & Terms', sit ahead of the demo CTA and add exits before the pitch lands.

Value props

78Fair

Title, subtitle, hero — do they sell the product's true value?

OneTriangle’s headline sellsCheaper & Faster InferenceBy using frontier research on KV cache transfer between models, cut your inference costs and time by 20%. Prefill runs on a small model, and decode on a large one.

Working

  • Names the two outcomes buyers want
  • Subhead gives a concrete 20% number
  • Hero diagram shows the mechanism

Could improve

  • Headline is generic comparative copy
  • 20% claim buried in subhead
  • No quality/accuracy reassurance
