It looks very good!
I have a few concerns about the copy, though:
Beautiful Stripe Checkout Forms for WordPress
This isn’t a fashion accessory. Is the most important thing about the forms that they are beautiful? Why not focus on a bigger problem? What is the main reason why your potential customers need your plugin? It’s better to talk about the problem that the plugin solves, not about the plugin itself. Do your customers want to increase their conversion rate? Or is it something else? Figure this out and make it your tagline. Just ask “Why?” for each of your main statements:
Example. Let’s pretend I’m your potential customer:
"Beautiful Stripe Checkout Forms for WordPress"
Why do I need Beautiful Stripe Checkout Forms for WordPress?
"In just minutes you can start accepting payments with Stripe’s highly optimized forms."
Why do I want to receive payments through Stripe?
Why do I need to setup payment through Stripe for Wordpress in just minutes? What other slow and painful solutions are there? Do I need to touch code to implement them? If I know nothing about code and I need to modify code, I will shiver at the thought.
I agree with what @bradt said. I just want to expand on one of his points:
You may also consider a section that makes it clear why you need this plugin in addition to Stripe. Why can’t I just copy Stripe’s embed code and that’s it?
I would ask the same question or “Why do I want to use your plugin over other Stripe Wordpress plugins?” The answer to all these questions is benefits.
You’re only listing features on the entire page. Features come after benefits.
So, again, I ask the “Why” questions:
Forms that Convert
Why do I need forms that convert? Maybe my conversion rate is low.
Optimized for Mobile
Why do I need it to be optimized for mobile? Maybe my mobile customers leave at checkout. If you remind me that, say 70%, of my mobile visitors don’t complete the checkout form, whereas on desktop I don’t have such a problem, I will feel the pain. I’m losing customers. I want to do something about it. Then, if you tell me that there is a solution to this problem and that solution is to optimize my Stripe checkout form for mobile, I will be interested. I will ask “How do I optimize it?” Then, you can tell me that you’ve got a ready solution for my problem. I just have to install it on my website in 5 minutes. You prepared me for the sale. You reminded me that I have a problem. You told me that this problem can be solved. And then you offered me the solution.
I hope this makes sense.
Best of luck with your business!
