Don't use CTAs to drive people to your homepage, for instance. Even if your CTA is about your brand or product (and perhaps not an offer like a download), you should still be sending them to a targeted landing page that's relevant to what they are looking for and includes an opt-in form. If you have the opportunity to use a CTA, send them to a page that will convert them into a lead.
One surefire method of finding leads through content is to create something that you think will be really valuable to your industry or potential customers – like a whitepaper, research study, guide, or book – and placing it behind a form on a landing page. Those who want to access this content will need to enter their email address to access it. From there, you can begin a lead nurturing email program (which you’ll read about below), or even send a quick "thank you" message. If they enjoy your content, your lead might return your email, and could eventually convert.
