Divi is already the most powerful WordPress landing page builder on the market. Now backed by the Divi Leads split testing system and in-depth statistics, it has also become the most effective. Divi Leads makes it simple to test different content and design variations to determine which versions result in the highest conversion rate to your specified goal. A simple test can result in reduced bounce rates, higher click-through rates and more sales. Divi tracks it all for you!
