Thanls a lot for taking your time to write this awesome comment!
The thing is we have very little control over the checkout area, since it is hosted by our payment provider and we cannot run tests there. We are not happy about it and we will move to Stripe as soon as it will be available outside of the US.
Really, thnaks a lot for this. I will look into this right now, maybe we could fix some of those.
EDIT: We've removed the quantity field from the SaaS products, never thought of that before, thanks.
I think wording in the subject line is important, because it is the only thing a user sees. There are no other factors that affect whether he will open it or not.
Macro Recorder is really popular and most of the visitors are already "pre-sold". They don't care about the landing page.
We used to run tests on that page, because it has 1k daily visitors, we thought that we could test ideas more quickly. That was before we realised, that we can't rely on the results.
We even used false conclusions, based on those results, to make changes to landing pages for other products. Perhaps the biggest mistake we've made.
I'm sure, everyone here would love to hear what's wrong with it. No, really, if you do that for a living, you most certanly have something to add to the discussion.
Yes, but those things are impossible to track. If metrics changed weeks later, there is no way of knowing that it was caused by a test you run earlier.
Those things happened (and still happen) a lot to us. At first we were all excited when there was a significant difference between alternatives, but now I just assume that something is wrong by default.
Yes, maybe we didn't have enough motivation because of lack of feedback. In fact we did have the live demo planed, but it seemed like an unimportant feature.
We really should put a little more effort into this project.
Thanks for the feedback. We really thought of at as an MVP from the beginning and put up a website in one day and spent the rest of the time on the backend. Maybe you're right and that's the reason why we're not seeing any demand.
We've launched http://heattest.com/ two months ago. It's an app for heatmap analytics, which was a pretty hardcore to develop. We've spent a lot of time to make the algorithm really good and reliable, but so far we have like 3 sign ups in total, all of them for free trials. The market looked really promising at first.
