To me, this is the #1. I would go so far as to place that 'first_time_ab.php' box directly at the top of the page. Kind of an 'enter your webpage and get started NOW' type call to action.
After seeing this link, it's totally clear to me and i will definitely sign up when we're ready.
Thanks for your feedback. We will definitely A/B test your suggestion. In fact, had been meaning to test the demo with the input box for a while now.
I'm trying to do a test, where one variation has this text box and nothing else (kind of like Google homepage). My only worry is that it may spook some less technically savvy people into thinking we have hacked their website!
I agree strongly. If I can paste my url into a demo site, and and get a taste for how easy this would be for me to a/b test my next question is what do I have to do to make this happen? A blurb telling me all it takes is copying and pasting one line of code takes care of that. Maybe show a video showing how easy it is - how long would it take? under a minute?
