Mobile gets more attention here than on almost any comparable blog, which is the one thing separating these posts from every other run of marketing tips. Spencer Rollins covers designing for a phone, what changes when somebody arrives from one, and why a site that works on a desktop can still lose that visitor.
There is also a post on server headers, which is oddly technical for the genre and useful for exactly that reason. Most writing at this level never gets near what a server actually sends back.
The remainder covers affiliate promotion, blogging, search and social media in the standard way, with the standard advice. None of it is wrong and none of it is anybody's own experience.
Thirty seven posts. Take the mobile and technical ones, which are specific enough to act on, and treat the rest as a refresher if the subject is new to you.
