I made some changes to my site, mostly aimed at overcoming Panda penalties.
I noindexed index pages, and somewhat changed the site navigation to organise by theme better.
There has been a small improvement is Google rankings, but I am getting a LOT more traffic from Bing. Bing seems to have indexed the changes fully (the noindexed pages have disappeared from Bing) which Google has not.
Can I infer that Bing was penalising me in a similar manner to Panda penalties, and I have escaped it?
