What's an easy way to give a website an SEO audit if you've never done it before?

A SEO audit is a process for evaluating the healthiness of a web site in a number of areas. The auditor will check the web site against a checklist and come up with recommendations of what needs to be fixed (because it is wrong) and what needs to change so that the performance of the web site in search engines is improved.
