Well, this may be slightly off-topic, and not remotely musical in nature...but somehow I've found the time to write a book. About SEO.
It's called "Super Simple SEO: How to make Google love your website", and it aims to demystify the whole topic.
Written in a friendly, jargon-free way, the book is written for website owners who need to get to grips with SEO without spending a fortune on consultants or online courses.
