Every professional blog should have RSS tracking for feed subscribers, an email list signup form, and an analytics package. I recommend Feedburner, Mailchimp, and Google Analytics along with a few helpful related plugins.
One of the first things I’d recommend doing after launching your site (or even right after you come up with your brand name) is to go out and register your username on the top social media sites. This is great for both reputation management and to start participating in relevant communities.
Your logo is often the first thing that people will see when they visit your website. While it’s possible to just use a text header when starting out, I’d highly recommend getting a really good logo from the beginning (bad logo design can actually cost you). Logos help establish your brand and credibility.
Now that you have your Wordpress blog installed and setup, you want to make your website look good and stand out. In Wordpress that’s done by downloading and installing themes (they’re basically skins or designs for your blog). What you will want to do is download or buy a theme, pop in a new logo, customize some parts of it to make it your own, and install some plugins. Let’s tackle themes first.
