Frequently Asked Questions
What is a CTA Analyzer?
A CTA Analyzer evaluates call-to-action copy — button labels, link text, and sign-up prompts — for clarity, action-oriented language, urgency, and ideal length. It helps improve conversion rates on landing pages, emails, and ads.
What makes a strong call-to-action?
Strong CTAs start with a verb (Get, Start, Download, Join), are 2–5 words long, create urgency or value (Free, Now, Today), and tell the user exactly what happens when they click.
How is the CTA score calculated?
The score weighs word count, presence of action verbs, urgency words, value words (free, save), second-person address, and penalties for vague phrases like "Click here" or "Submit."
Is my text stored or sent anywhere?
No. All analysis runs entirely in your browser. Your CTA text never leaves your device.
Is this tool free and does it work on mobile?
Yes on both counts. The CTA Analyzer on draft21 is completely free with no sign-up required and works on all devices.
