E-book writing is definitely an art and requires a lot of creativity.
However, when you get in to the idea of marketing your products with your e-book, then you have to take in to consideration quite a number of things.
By profitability of the creation of an e-book, we mean whether it served the specific needs that it was created for and whether the investment in the e-book was recovered by sales that the e-book promoted.
If it did, definitely e-book writing and distributing is a good option for you to improve your sales.
How can you effectively write a good and saleable e-book lies in how effectively you understand your readers' psychology and what they expect to find in your e-book.
Try to know who the target readers are and get to know what they want.
Once you have got to know who your target readers are, cater to their interest.
Do not be too rigorous with the language but do not be too free flowing either.
Maintain a desired level of rigor and try improving on the graphics.
Readers like to read anything that pleases the eye, especially when it comes to reading on screen.
Also, provide sections, sub-sections, chapter headings and a table of contents.
Once you have undertaken the task of writing an e-book, plan your chapters and sub-chapters and set a time limit for yourself and stick to it.
Writing an e-book is a rigorous task and you will not finish unless you have you time limits under control.
