Backlinko Signup form

Backlinko’s signup section is a masterclass in clarity. One headline, one testimonial, one action. No fluff, no distractions.

The smart design behind it

The headline instantly positions Backlinko as the missing link between learning SEO and doing SEO. Then, a recognizable testimonial from HubSpot’s VP of Marketing adds instant trust and authority. The simple “Try It” CTA makes the offer feel low-commitment and inviting.

Why it works

• Puts social proof front and center
• Uses authority bias with a well-known brand name
• Keeps the copy laser-focused on one message
• Makes the form frictionless—just one box
• CTA feels like an experiment, not a contract

Examples

• Morning Brew uses big logos of readers’ companies to boost credibility.
• ConvertKit’s form highlights real creator income case studies.
• Basecamp’s signup page features testimonials from recognized founders.
