Businesses should promote their lead magnets in places where their target audience spends the most time online. This could include social media platforms like Instagram, Facebook, and LinkedIn, where they can create targeted ads to reach potential customers. They can also promote lead magnets on their website homepage, blog posts, and through email marketing campaigns. By using a combination of these channels, businesses can maximize visibility and increase the chances of converting leads into customers. For example, a fitness company could promote a free workout guide on Instagram to attract people interested in fitness and health.
