On 5 sites I used a simple, yet non converting theme. Rankings were excellent, and stable. I change the theme to a greatly converting theme and profits were 3x-4x during the 2-3 day span the rankings were there w/ the converting theme. Now, rankings have dropped from top 3 to top 200. I changed the theme back to the original on 4 of the 5 sites. The one site I left alone actually went back to it's positions even though it still has the new theme. The Other 4 sites who's theme has been changed back to original still has horrble rankings. How long does it take for the rankings to come back?
