Cons: The customer support has gotten worse recently. They used to have live chat on their site, now they use some weird ticketing software that I do not like. I will say this, there support is very good but a lot slower than I'd like. When they do get back to me, it typically solved my problem immediately. But sometimes it takes a full day or more for them to respond. This can be valuable lost time for a business, especially if you're running ads to a page that stops working.
Now all of this landing page theory is nice, but reading about landing page design and actually designing an effective landing page are two very different things. If you want to create landing pages for your marketing campaigns, you have two basic options: 1) build the pages directly on your site or 2) create the landing pages using a landing page tool.
A/B testing, or A/B split testing, is a method for testing two versions of a webpage: version "A" and version "B". The goal is to test multiple versions of webpages (e.g., home page vs. product page) or one specific element that changes between variation A and variation B (such as having a lead form on the left hand side or having it placed on the right hand side), FAQ to determine which version is most appealing/effective. This testing method may also be known as A/B/n split testing; the n denoting more than 2 tests being measured and compared. The data for A/B testing is usually measured via click-through rate or an alternative conversion tracking method.[11]

Inception Secrets: Do you suck at creating sales copy? The majority of people do. But that’s going to change with the Inception Secrets training. Make your way through the training curriculum, and you'll emerge a sales copy master. Make use of these skills to produce amazing copy for your own funnels, or charge for your recently acquired talent and assist other marketers with their copy.
Let’s be clear—leads won’t automatically move down the funnel. Sales reps have to continue to do their part of selling and allow the CRM to update the lead’s stage in the funnel by completing certain actions. You can setup workflow automations in the CRM to change lead stages. For example, after you’ve contacted a lead, the CRM will automatically update the lead’s stage based on the last activity.
As a software engineer myself, I can tell you that building funnels from an application standpoint takes massive amounts of work. There's a great deal of coding and integration that's required here. From email systems to landing page implementations to credit card processing APIs, and everything in between, so many platforms need to "talk," that it takes the bar too high for the average marketer. 

There’s a better solution: Build out an automated email follow-up campaign that speaks directly to this objection. Any time you encounter this problem, you can send that prospect information that seems designed just for them. A multi-month educational campaign may reduce their content anxiety and nurture them toward a sale. Yes, it’s work up front, but once finished, this campaign will work for you always.
