Hi.
Your sales letter is actually an e-letter, but never mind.
After reading it all I have a feeling I do want to know what you are going to reveal in your e-book, but I wouldnt be pursuaded to pay the $10 to find out.
In other words....your letter works well in parts but isnt convincing enough.
This format is fairly common on the web these days and by all accounts some people make plenty of cash by utilising this form of selling.
How to improve yours?
1, there is too much blank space around the upper third of the letter....I had to scrooll down a good way before I seemed to come across interesting stuff.
think about reducing the size of the header [and maybe get a more professional image.....try SXC for good quality free images http://www.sxc.hu/]
2, tighten up the text + images in this area into a more compact area.
3. get a more professional version of the e-book cover done. [with a relevant image. Is that the surface of the moon on there.....
]
4. add more content to the body copy, perhaps give more 'teasers' about whats in your e-book.....make me so curious I am will be convinced to cough up the $10 to read it all
5. make your book $9.95 [old trick but still worthy]
Hope this has helped in some way.
Regards
C.S.
