6 more things: 1.- Preview button: The button is almost invisible, it needs to stand out a lot more, needs to contrast with the blue . 2.- the font choice Maybe people don't like the font? The font is hard to read, not friendly, gets tiring. The best font for reading printed matter: Serifs (i.e. Garamond, Gentium) The best font for online reading: Sans Serifs (Helvetica, Arial, etc) You need to make font samples: print the same page 6 times, each one using a different font, like this: http://webstyleguide.com/wsg3/figures/8-typography/8-9-common-fonts.jpg http://webstyleguide.com/wsg3/figures/8-typography/8-9-commo... . . 3.- Did you use inDesign? The margins are too wide in my opinion, too much whitespace . 4.- Show 2 or more PDFs: Maybe people need more proof to convince themselves? i.e.: Sum example PDF preview, Multiplication example PDF preview etc . 5.- File size Maybe people think the file it's too big? InDesign and also Adobe Acrobat have an optimize setting. . 6.- Testimonials: Maybe people need social proof to convince themselves? Testimonials are great social proof. . . P.S.: use a post-it! P.S.: I'm a designer btw
