I have a small niche based site that is a little over a month old, that was ranking quite well for my 2 main search terms on Google, top 15 results and rising. I recently updated the site a week ago, changing the home page from a blog to a static Wordpress page and moved the blog to a Wordpress page named "blog". 24 hours after updating the site all of my rankings dropped, currently outside of the top 500 results. No changes to URL structure occurred, it was not hit by Panda or the EMD update and it wasn't de-indexed. It has been a little over a week with no come back in any of the ranks. Just wondering if anyone has done this before and roughly how long it took for your rankings to come back?
