CTA

42Poor

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

Problems

  • no button or in-product action
  • nav pills are labels, not actions
  • paid offers only linked in body text
  • video chip is player UI, not a CTA

Mobile web

48Poor

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Five-link nav row — Full desktop link row is kept instead of a hamburger, eating a slice of the first viewport.
  2. YouTube video embed — Video stands in for a CTA — no tappable conversion button exists anywhere in the mobile fold.
