I have also created a free guide / PDF, to hopefully convince them to subscribe to my list. Not a long one (8K words), but I think it went out good.
My first question is: How well does a pdf report still work to get opt-ins, in comparison with audio or video?
It seems I am forced to go with pdf format for everything, but I'm still concerned about opt-in rates.
Reason: I have several difficult problems with creating audio version. My voice is by far not perfect, and also I have a permanent allergy/blocked nose problem, so recordings are never great and I need days of work to get them cleaned, then I'm still unhappy about the result.
I have also tried using professional voice but I'm not really happy about that either, it adds a different layer of problems. Like confusing users by using different voices, sometimes your regular voice-over isn't available, and it's not your voice (they expect it to be) and so on.
Second question: What do you think about adding a second, synthetic voice version together with the pdf report? That's easy to create -- but far from natural. Still robotic, although they've improved significantly though.
I'm considering adding a digital voice version, as it doesn't cost me anything and perhaps someone will use it instead of reading. I don't know how my readers will take this though, even though it's a free addition. Side note, my money product is an ebook.
Please enlighten me. Thank you very much!
