Thanks for sharing.
Here is some honest critique for you: It's about more than marketing. Where they are blowing you guys away is usability -- partly in the product itself, but more on the website.
In less than 100 words I know: a) exactly what showoff does, and b) exactly how to get it up and running.
Compare that to your Quick Start guide: https://pagekite.net/support/quickstart/
I mean, my eyes just glaze over when I see that. Get me running and get out of my way. As someone else in the thread said, don't waste my time selling me "benefits" -- that's what enterprise salespeople do to enterprise buyers.
Also, I like that you have a free trial, but when are you going to tell me how much it costs? And do I really need to complete an optional survey and check a terms of service box?
Sorry if I sound like I'm being hard on you guys, but even though I don't know you at all I'm confident you're capable of more. :) Don't fall back on the "we're not good at marketing" excuse. Spend a lot of time thinking about how you can simplify, simplify, simplify, simplify every single aspect of the interaction on your website and your product itself.
I'll keep my eye on your product though. Thanks.
