I've noticed on quite of these WSO guides (reports, ebooks e.t.c.) that they are usually well written. The problem that i see is that many of them are missing page #'s or headers / footers.
With great word processor editors such as microsoft word or open office, it really makes it somewhat easy to add these elements to your how to or case study guide and give a more polished look. Not only that, but you have now made your guide even more functional and your buyers will be even more appreciative that you took the time.
I'll give you an idea, on a 100 page plus WSO, it was well written and easy to follow with nice table of contents e.t.c. with what pages you can find what topic, but they were no actual page #'s on the pages! Do you know how frustrating it is to see a topic on say page 36 in the table of contents and not actually have page #'s on the bottom of the page to refer to said topic?
This leaves the reader to thumb through and 'guess' where the topic resides by manually counting the pages e.t.c. In any case, yes it's not a huge deal but these are the small things that keep buyers coming back.
Another good point is that if you're going to make a video course, you should really take the time to get it transcribed as well for easy reference. This is huge. Many people prefer watching videos and referring to the written transcripts for tackling a specific issue. It's really hard to get into a 20 or 30 minute video and you just want to find one of the key points. Even if you have to bump the price of your video course, you'll have more of that 'thump' factor that results in overdelivering to buyers -so it's a win-win.
Taking the time to hone in on these little specifics can make a difference, so i just hope this may help someone.
