SEO? ROI? LOL?

Alright, lately I've been feeling the need to get into some serious SEO. Lately, over at Dream In Code, it seems as though there is a spark of interest with optimising sites for search engines. I'm trying to keep up, but man alive, these kids know how to do it. So here's what I have done... an experiment, have you. I have basically started fresh with my site structure (which goes unnoticed by the average viewer) in an attempt to climb in the Google search queries. But before I can climb with such drastic changes, I must fall at the foot of Google. Here's a few steps I have taken so far:

• I moved my entire blogs from Blogger.com and Myspace to a home-brew blogging system I have periodically been working on with my free time. I also resurected blogs between 2002-2004 from old home-brew systems I have made. The MSN Spaces era in my life is all that's left. My Blogger account is slowly diminishing in google (when searching for "Nick Davis")
• I have decided to stick with the domain of  http://www.nicholasdavis.info. For the most part, I was sick of the ".org" look. It's funny and all, having the organization domain, but alas, I'm not an organization. I figured .info was alright, as it is information on me. Unfortunately, I believe it kind of puts me at a disadvantage compared to it's .com and .net brothers.
• I changed all my page titles to something a little easier for google eat up. On Analytics, people do more searches for "Nick Davis" than "Nicholas Davis". I took that knowlege and figured "Nick Davis" was probably better in the title, especially if I want to tackle those keywords more.
• I created an RSS feed for the mass populace to consume, of which I have created a modified version for Google to eat up, using Google Webmaster Tools.
• I submitted my site to Google.
• I reconstructed my blog template so that it will be easier for search engines to pick up on. Technorati seemed to enjoy it a lot.

So far, my Google presence seems to be improving a little since last week. Searching for "Nick Davis", my blog page shows up at the very bottom. I'm hoping the next couple days, it will be my home page and a couple notches higher than the bottom of the first page. I suppose I also need to work on blogging about things that are interesting.

This blog is my personal experience and for the most part very speculative. So if you have any information or tips, please let me know! I'd love to hear from you.
