That's why getting them to agree to something like a free + shipping offer or by agreeing with something you've said in some way. This is a powerful principle in sales and if you pay attention to some of the best marketers in the world, you'll notice that they work fervently to get your commitment to something, even if it's very small in the beginning.
You might be doing all the right things to generate leads -- landing pages, gated content, contests, and more. The problem might be that the design or copy itself isn't driving the engagement you need. A/B test (also known as "split test") different aspects of your list-building campaigns with different versions of the same content. This includes the call-to-action text, the color of the gated offer, the time of day you're posting to social media, and even where on your website these signup forms are placed. Sometimes a small change can drive hundreds more conversions.
