Opt-In Rate
Quick answer
What is opt-in rate?
The percentage of visitors to a page who give their email or register, out of everyone who saw the page.
In plain English
Opt-in rate measures how well a lead magnet, landing page or webinar registration page converts curiosity into a contact. It's one of the first numbers to check when a funnel isn't producing enough leads.
Example
1,000 visitors, 350 register for the webinar = a 35% opt-in rate.
