When to use it
When the homepage or about page states a customer count but the signup CTA on the page with the most paid visitors doesn't.
How to run it
Add a one-line count beside the signup CTA, like 'Join 50,000 marketers'. Test a recency frame, '5,024 companies signed up last week', against the lifetime total.
Why it works
Make it safe to believe you
A big number is social proof that does the convincing for you. Basecamp ran 'Just last week, 5,024 companies signed up' above its signup form as auto-updating proof of momentum.
