A personal website review is one of the best ways to improve your online business because the advice is personalized and actionable. Because I'm in the business of advising people, it's only natural that I offer this service!
For the most part, yes! There are some aspects of running a website that are going to be relevant forever -- they just don't change.

You absolutely don't need one. However, it can only help you. With each review, I aim to provide you with information that took me years to accumulate myself. I'll take the guesswork out of some of your work and help lay out your strategy for the future. You can do this stuff yourself, but you can also skip the guesswork that could lead you in the wrong direction.
