I wrote a number of giveaway guides which I then found I had to keep on updating as the WordPress technology developed and changed. And feedback from my readers prompted more and more words, until the free handbook became almost a full-sized book.
Fast forward to Kindle Publishing after one of my friends in the US urged me to make it available on Amazon. I compiled all the material I had generated into a twenty lesson guidebook, designed what I hoped would be an eye-catching cover and submitted it to be published. Amazon accepted it and put it on their website.
And it people started to buy it. And it became a best-seller. And the rest is history… 🙂
