My biggest problem with leadpages and instapage is they are super expensive. For someone starting to start out on a shoestring budget, lots of times those aren’t great options. I personally tried LeadSanity.com and it works great for me. They certainly aren’t as feature-rich as the other guys, but they have a free version and their paid accounts are cheap as hell. Just my two cents.
Convertri Lifetime Deal was the best thing... while it lasted. Now it is not available anymore - and no chance of it ever coming back. However this ONETIME ANNUAL DEAL is next best to help you kickstart your online business eg. Local Businesses, B2B Lead Generation, Information Products, Coaching/Consulting, Ecommerce, Network Marketing, Blogging or Affiliate Marketing, etc.
No Conversion Rate Optimization Software will manate to cover all the needs of a specific team. Though core functionalities of Unbounce and Leadpages should matter you should also carefully study the integrations offered by every service. In many cases you will already be making use of some other B2B software in your company and it’s much more beneficial to opt for services that integrate well with each other. That way you will be able to ensure a reliable transfer of information between your teams and services, which can considerably reduce time devoted to migrating between one software and the other.
