The Diary Of A CEO Landing page — Behind the Diary: “Join 450K subscribers”
Why it works
The ad’s line as the headline: “Have you ever felt like nobody else thinks the way you do?” Then the promise: “Once a week I write a letter. The things I’m thinking about at 2am, the decisions I’m wrestling with, the stuff I’m figuring out in real time. Straight to your inbox every Sunday.” One field, and the subscriber count on the button instead of “Subscribe”. The background cycles through behind-the-scenes photos.
The whole page on a phone: name, headline, one paragraph, email field, “Join 450K subscribers”, a consent tick and his social links.
