Mobile is where this one puts its weight. Daniel McGilvary returns to it repeatedly, on what mobile marketing actually means, why a small business should bother with it, how the messaging software works, and what to send when the screen is tiny and the person is walking somewhere.
The remainder covers the familiar set. He asks for consistent colours and a readable font so recipients know an email is yours before they read a word of it. He wants new articles announced on the social accounts you already run, so one piece of work counts twice. He recommends guest posting as a way of borrowing an audience you have not built yourself, then takes search optimisation and hosting choices in turn.
The advice stays general rather than personal and does not pretend otherwise. A review of an online role playing game sits in the middle of it, and that is the one place his own voice comes through clearly.
Take the mobile posts if that is the gap in what you are currently doing. The rest works as a quick refresher.
