Thanks, I'll do some researching.
But I don't think it's very difficult to rank high for keywords - especially if 1) the KEYWORDS are in the domain themselves and 2) there is not too much competition and) they are actual products/services (like those in my signature that were made over the past 2-3 weeks).
For instance, I created a 1-page lander for my SleepNaturally.com domain (just some unique paragraphs with interesting content, a few ads etc.). Not really optimized. But noticed just today that it already ranks on the 1st page for "sleep naturally" - it was only put together about 5-6 weeks ago.
I expect most of my little sites (in signature) to rank somewhere in the top 1-3 pages over at google.com - maybe in 2-4 months time. Was just really surprised to see Cameos.net "disappear" after ranking on page 3 after just 2 weeks of going LIVE. But now I know it will rank again in the not-too-distant future (Federer says, still hoping)...
