Value props

72Fair

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

StarSling’s headline undersellsAgent-native CIFast GitHub Actions runners with AI agents that continuously optimize your workflows

Working

  • Subhead names the concrete product
  • "Continuously optimize" hints outcome
  • YC badge + free CTA lower risk

Could improve

  • H1 is insider jargon, no payoff
  • No numbers or proof in the fold
  • Hero orb decorates, shows nothing

Information hierarchy

78Fair

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

Information hierarchy annotations on the desktop capture1234
  1. Review Runners button — Secondary CTA sized and boxed nearly equal to the primary, splitting the click decision.
  2. Read the post banner — Boxed banner button is the first exit visitors see, pulling attention before the hero loads.
  3. Header Get Started link — Duplicate CTA in the nav competes with the hero button instead of reinforcing it.
  4. Continuously optimize link — Underlined link inside the subhead adds an exit path in the middle of the value prop.

Mobile web

78Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Decorative sphere graphic — Large ornamental sphere pushes the primary CTA below the first viewport.
  2. $3M promo bar — Sticky announcement bar eats top-of-fold space with no conversion CTA on mobile.

CTA

84Strong

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

Problems
