CTA

68Fair

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

Parameter

Problems

  • 'call' feels costly and committal
  • sells the meeting, not the payoff
  • microcopy payoff not in the label

Value props

82Strong

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

Parameter’s headline sellsSecurity at the speed of development.AI agents that find vulnerabilities in your web apps, APIs, and infrastructure. Continuously, not once a year.

Working

  • Names the speed-vs-security tension
  • 'Not once a year' hits pentest pain
  • Numbers strip adds hard proof

Could improve

  • Hero art decorates, doesn't demo
  • $30B+ claim strains credibility
  • '24 hours' proof buried under CTA

Mobile web

82Strong

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Side-by-side CTA pair — "Book a call" and "Learn more" keep desktop proportions instead of stacking near-full-bleed for the thumb.
  2. Pixel-corner CTA styling — Decorative pixel blocks on "Book a call" clutter the button edges and blur its tap boundary at phone scale.

Information hierarchy

84Strong

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

Information hierarchy annotations on the desktop capture123
  1. Learn more button — White fill on dark background out-contrasts the blue primary CTA, splitting first-glance attention.
  2. Book a call CTA — Pixel-corner decorations blur the button's edges and shrink its perceived click target; also duplicated in the nav.
  3. Proof metrics strip — Low-contrast dark-on-dark panels make $30B+ and 24/7 proof easy to miss on scan.
