Hello there, and thank you kindly for your interest. Instead of dithering on about my credentials like every other writer (though they are extensive - see my portfolio), I will demonstrate to you what I can actually contribute to this project, as I have worked with digital marketing content for more than a decade now.
Here are some of the steps I would include in the eBook, per your tentative outline:
-Identifying and researching your target demographics (who are they? where do they hang out?)
-Developing PPC, social, native, and other ad campaigns to best target these demographics.
-How to target mobile vs PC vs tablet.
-The finer points of email marketing: segmentation, auto-responders, most appropriate frequency, etc.
-Landing page design and psychology
-Everything you need to know about affiliate marketing (I have a TON of experience in this)
-Per above ^^ Putting the price in PPC ad headings to increase conversions, natural language with LSI anchor links to avoid penalty, free advertising methods (twitter search, FB groups, forums, etc), and so on.
I don't want to give away too much for free, of course :)
Now onto the dry stuff:
I've been writing for ten years. EBooks, blogs, articles, white papers, and so forth. Many of these have covered digital marketing topics. I have run my own affiliate, PPC, and social advertising campaigns. I've designed and launched landing pages, affiliate blogs, microniche sites, and more.
Cheers, hope to speak soon!
