CTA

76Fair

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

Problems

  • generic label, no payoff named
  • no headline echo
  • no offer signal (free/trial unclear)

Value props

76Fair

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

Stamp’s headline sellsThe AI Secretary That Drafts Your Replies.Stamp learns your preferences to draft, prioritize, summarize, and schedule in your voice, with your context.

Working

  • Names the concrete job: drafting replies
  • "In Stamp's voice, with Stamp's context" kills objection
  • Screenshot shows a real drafted email

Could improve

  • No numbers or proof points anywhere
  • Mobile "Email, handled." is too vague
  • No emotional payoff like hours saved

Information hierarchy

82Strong

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

Information hierarchy annotations on the desktop capture123
  1. Seven-item nav row — Features, Pricing, Downloads, Blog, Contact, Sign In offer six exits before the hero CTA gets a look.
  2. Header Get Started button — Same weight and label as the hero CTA below, splitting the primary action into two equal targets.
  3. Play button — High-contrast pill pulls attention toward the demo before the hero conversion is made.

Mobile web

84Strong

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Hero Get Started button — Desktop-proportioned at half the column width instead of a full-bleed thumb target.
  2. Header Get Started button — Duplicates the hero CTA in the same viewport, splitting the tap decision.
