Like LeadPages, but specifically designed for WordPress sites. Again. Thrive hooks into WordPress and allows you to create highly customized landing pages, along with their specific Thrive Leads plugin. Thrive Leads is a two-step opt-in plugin that mimics the beneficial functionality of the LeadBox. If you’re too attached to WordPress or your existing blog to migrate to a LeadPages site, this option is perfect for you.
Unbounce also lets you create sticky bars for your site. These bright forms draw attention to the offers and help to get more conversions without paying for more traffic. The editor allows you to add pop-up windows (which are called overlays here) on exit, on arrival, after a delay, on a scroll, or on click. There are plenty of pop-up templates to choose from, and you may also customize them. This feature is not available with Instapage.
