Eben Pagen talks about moving the free line, and giving good quality content away free upfront before to build a relationship. This is sound advice which I subscribe to.
I did a little unscientific test last week, just to get a feel for how far I can move the free line and still get results. This is what I did (btw, it didn't work too well for me. I should also say I'm not really driving a lot of traffic to this site at the moment, but I have a feel for the number of people signing up to download my free book).
Normally, when visitors arrive at Download the Best Sellling Book Millionaire Upgrade for FREE (Inspired by a flight with Sir Richard Branson) they have to enter their contact details to download this book for free.
The bounce rate seemed high to me on this site, so I though asking visitors to give their name and email may be off putting, so for all of last week I changed it so that visitors could download 2 chapters of the book without giving their details, and then if they wanted the rest of the book, they could subscribe and get it all for free.
During that week, I noticed a dramatic drop off in signups.
On Sunday evening, I switched back to my old signup page and required visitors to give their details to download the book, and the signup rate stepped up again.
Perhaps I moved the 'free line' too far, perhaps I was getting better quality signups last week (even though there were fewer), or perhaps visitors just didn't like the first 2 chapters!
Marketing is a funny old science and I'm still very much working it out! But I don't think I'll move the free line that far forward again!
