There is absolutely no correlation between having a high Page Rank and outranking competitors. Go search for "hacker news" in google and you'll see that www.thehackernews.com (a PR 0 url) outranks twitter.com/hackernews (a PR 6).

The reason your site dipped out of the rankings is because when Google crawls a site and there have been significant changes to the structure (new theme, new internal linking structure, missing pages, etc), they yank you out of the index in order to reevaluate your proper position before moving forward. This can take a day, a week, a month, or half a year to recover; there is no way to predict how long it will take.

Try and replicate as much of your old site's structure as soon as possible, and just give it time.

I will do that, thank you. The old site structure was quite messy, with ugly URLs and links going back and forth to pages. I think this new scheme is much cleaner, now, as it's just a few links to pages. I'll try to add some categories or tags, though, and see how it goes.

Thanks again!
