Choose relevance over novelty
The strongest lead magnet solves a problem that naturally precedes the product or service you ultimately want to discuss.
Formats
Checklists, templates, calculators, mini-courses, reports and practical guides can all work when the format matches the task.
Landing page fit
Keep the page focused on the specific resource, show what it contains and make the exchange clear.
Measure quality too
Track whether leads engage with follow-up and become useful opportunities, not only the raw opt-in rate.
