Like LeadPages, but focused equally between a stand-alone site and a Facebook tab. You can use both, or you can focus on one or the other. They have all of the email integration, analytics, and mobile functionality you’ve come to expect out of a landing page builder. As a special note, it accepts Paypal payment processing, which a surprising number of these apps don’t.
A word about ‘average results’: your conversions are dependent on a lot of different factors: your copy, your design, your offer, the market you’re making the offer to, so we’re not guaranteeing you any minimum level of conversions when you use a Convertri page.  Our test which yielded 25% better performance was done across 100 clicks to each page in the Paleo niche.  Will you get equivalent results?  We don’t know.  What we do know, and what we guarantee 100%, is that your pages when built in Convertri will load faster than almost any other equivalent page on the internet, giving you a better customer experience, and this often leads to better conversions (see: Quicksprout, eConsultancy, Forbes, Hobo-Web) – and that can only be a good thing.
Hey Martin, Yes Instapage is really good alternative to Leadpages. A/B test of landing pages are required, when a marketer need to test and optimize the performance of their existing lading page. Using A/B split test; they can change and optimize different elements of landing pages and see how the changes can impact their conversion to get high return.
