Drop in organic traffic after site redesign

[jlgpac]

Is it common for a site to see slight organic traffic drops (from Google) after a site redesign (containing cleaner code, more usability and basically just being more helpful for the end user)? A new site of mine went live last Wednesday and has since experienced this.

If you have seen this in your own site, how did you recover? And how long did the recovery take?

Was the redesign cosmetic or did any of the url's change, navigation change? So many different things can trigger a slight drop but knowing some of the information would be helpful.

This was mostly a cosmetic change. The navigation changed slightly but all the original links are still in place on the homepage. All url's stayed the same.

It's normal, and unless I change the URLs, everything is back to normal in a week or two.
