I definitely agree with what Joe is saying about your form on mobile. Here’s the variant that I’m looking at:
With the way that this variant is laid out, I’d say that the image is probably less important than your call to action, at least for what you want to be seen immediately on load, and you could probably improve your conversion rate by adding a bit of compelling text above the form.
You might try a variant putting your form at the bottom of the page and having your CTA button at the top (reverse from the way it is now). This not only puts your CTA in the visitor’s immediate field of view, but also gives you more of that precious vertical space to sell your visitor before they even have to touch their screen.
Have you tested a desktop variant with your promo video somewhere on the page (the one that can be played on the mobile version)? I’ve taken a look at a few different different variants and I’m not seeing your video on any of them. I’m curious if that was a conscious decision you made based on previous testing?
Personally, I prefer the variant without the animation in the header area of the page. IMO, the movement is distracting. My experience with both of the landing pages that had the animated background was that I watched the animation and and then scrolled down the page without really even looking (and definitely not absorbing) the header text.
All-in-all though, I think the content and layout of your page are really quite good. It’s very appealing and conveys trust and a level of professionalism that would be expected with an LMS platform. You might consider taking a closer look at your advertising channels at this point. You can have the best landing page on the Internet, but if you’re not driving the right kind of traffic to it, it won’t do you much good!
