Too Long; Didn't Read
A well-promoted lead magnet, such as a guide, a whitepaper, or a calculator, can be of interest even to people who may not know they have a need for your product. Free demos/Trials are one of the most effective lead magnets. White papers, ebooks, original data from surveys or other sources can be particularly effective as magnet leads. Interactive quizzes and calculators are short-form, quick, and dynamic, providing information without being overbearing.
