Well, what a beautifully fantastic book.
Completely up to date, realistic for anybody whether your a SME or anything but, with precise information that is straight to the point.
I have only ever used 3 resources for SEO, SEO for dummies, which was ok but a bit out dated from when i bought it due to Google's ever changing algorithms, an online ebook which was fantastic for starting out from Freeleadswebinar, and this book.
An Hour a Day is undoubtedly the best resource i have come across and i'm looking forward to using it and dominating my niche on Google. I wouldn't bother with SEO for dummies, but freeleadswebinar is good if your from the UK. This book is more universal and for everybody.
