Welcome to the Q&A Forum

Jason, Think of how many individual blog posts you're going to need to write in 2013, 2014, and beyond (one hundred, two hundred, more?) and how much social outreach you'll have to accomplish over that time in order to build the blog into a really effective marketing tool for your company. Then you  gotta wonder how you can maintain interest and focus writing all those posts on the specific subject of "atlanta plumbing company" or "choosing an atlanta plumbing company".  On top of that, gotta wonder how many of those social profiles you reach out to week after week after week who are going to want to share your content on the specific subject of "atlanta plumbing company" or "choosing an atlanta plumbing company". And then you gotta wonder about the readers and how their interest will be maintained while you're writing only on the specific subject of "atlanta plumbing company" or "choosing an atlanta plumbing company". I'd say that you're on the right path in thinking that your titles seem a bit spammy, but you've gotta get off the path and get on the highway.  On the highway, your blog can reach its greater potential--a vehicle that can reach and engage a community that is hungry for a wide variety of topics within your theme. As someone here at SEOmoz is fond of saying, content needs to be exceptional, inspirational, unique, credible, fun, and beneficial to share in order to accomplish it's goal of being an effective marketing tool. I would start with that, when contemplating your titles, and then write your posts accordingly.

My pleasure, Joe!
