I've had Tim Ash's book on Landing Page Optimization for over a month - and it was always on my mind to write a review (that's why I got an advance copy) but till tonight - I really didn't have a chance; my full review is at Landing Page Optimization by Tim Ash.
Last week, while talking with Tim Ash for an hour at Search Engine Strategies, I got a chance to get to know him better. True, I've seen Tim at Social Networking Conference in Miami, early last month - but I didn't get a chance to sit down and talk there.
I would definitely recommend the book to anyone wanting to learn MVT and Landing Page Optimization. Tim told me about a new service focusing on the availability of Conversion Audit consulting services for companies utilizing the web for business (it costs 5K-10K depending on how many services "convert" and you can read more the about the Conversion Audit here.
