Drupal and SEO

So it's pretty incredible that two sites I registered just a month ago are now listed in Google. I installed drupal on both these sites and miraculously they are now being indexed. Not in MSN or Yahoo yet, but that's pretty cool. From what I've read, the Google "sandbox" (if there is one) can often keep a site out of the search engine for months. I'm now starting to write more articles to add more interesting content.
