First, is it working?
Complete your own funnel: does the contact appear, does the thank-you page load, does the first email arrive? If not, the problem is setup, not persuasion.
Then read the numbers
Insights → Analytics → Funnel Conversions, and the funnel's Overview. Many views and few leads point at the headline or the form. Leads and no sales point at the offer or the emails.
Quick fixes
A headline about them, email plus first name only, one testimonial, an image of what they get, and urgency only when it is real.
Benchmarks
Lead magnets: twenty to forty percent opt in. Webinar registration: twenty to thirty. Sales pages: one to five.
