CTA

30Poor

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

Serna Bio

Problems

  • no CTA anywhere on the fold
  • nav links only path forward
  • headline promise has no next step

Value props

48Poor

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

Exonic’s headline vagueImagine if medicine could sense and adapt to disease

Working

  • Evocative, emotionally resonant vision line
  • Blue highlight on "sense and adapt" focuses the claim
  • YC badge lends early credibility

Could improve

  • No subhead saying what Exonic actually builds
  • "Imagine if" is hypothetical, not a claim
  • Hero visual decorates, doesn't demonstrate

Trust

48Poor

Proof that the product is real, competent, and safe to try.
