As far as hemi wondering about rankings, different search engines use different ways of determining how they rank based on keywords, how many links there are to your site ect. I also read up on that too a little. But you can submit your site to search engines like google and yahoo, dmoz.org, to get your site submitted in to search engines. Much imformation can be found on rankings too if you search and read. My old site actually got pretty good rankings when searching for specific keywords, but my new one doesn't seem to be ranked as well for some reason.
