Several others have discussed technical aspects of the site. My review is from a different perspective. I hope it helps.
I like some aspects of the site, but it looks like your client is trying to be all things to all people. Trying to SEO a site for Real Estate, Tax Services and IT Project Management will be difficult. When I first look at the home page I am a little confused about what it is your client is really offering. So I started to read the text, which most users probably won't do. I did notice quite a few grammatical and spelling errors throughout multiple pages of the site. Here is one on the home page.
LOOKING FOR A QUAITY VENDOR? (quality is spelled incorrectly)
This is not meant as a hit on your implementation, but as constructive criticism. I know you are working with a client who probably has ideas of their own. And you have to work within that environment.
Here are a few questions that come to mind.
Is your customer trying to build a community for real estate that stretches beyond the ATL? I think it is one thing to offer properties for sell and yet another thing to build a community. What will draw people to get engaged on the site?
When I first look at the home page, I like the second layer of graphics with the roll over effect. But I don't make an immediate connection between Buying Real Estate, Community, Newsletters, etc. And when I click the Newsletter page, I get redirected to a DNN registration page. I kind of understand that you might want me to register on the site to get a newsletter. But I do this for a living. Most visitors might not understand. So you need to tell the visitor why they are on a registration page. And you might consider setting up an AutoResponder account so that you can just collect a name and email and run the newsletters through the autoresponder.
Are the Articles, Blogs and Newsletters mainly intended to create a larger site for SEO purposes or to entice people to come back on a regular basis?
On the Free Quote and Contact Us page you are using a particular container that is either not rendering properly or is just not good for your content. The title
Finding a Quality Company is Quick, Simple and Free!
is fading out as the container has a gradient and the text is white.
Well, gotta run for now. Hope this gives you some ideas on making the site the very best it can be.
BTW, I am just south of you down in Macon, GA. I come up to the ATL quite a bit. Maybe we could get together sometime. Is there a DNN user group in Atlanta?
