I've been doing seo for 7 years now. I started off when I was running my own graphic firm with webmasterworld.com and then along came seochat.com shortly after. I also subscribed to seochat's webdev newsletter which is very helpful. All of the sites I work with (currently it's down to around 7) are all on the first page for the most competitive keywords in their industry (including my own sites). It's actually not very hard as long as you keep up with reading and learning about seo, you can achieve great rankings. When we finally switched our trailerandtruckparts.com site to 3dcart, I was really worried that since there would be such a dramatic change (adding around 1200 more pages and changed page names, different layout etc. I thought the big G might throw us in the sandbox. Well, it's only been almost 2 months, and it hasn't happened yet, but I'm not holding my breath.

If anyone has any questions or would like any help in this area, let me know, and I'll do my best to assist to a point.
