Just wanted to update. My site which came back on June 17th (Panda 2.2) is still doing well on Google - but has fallen back on Bing by about 12 places.
I think it's because of the tag pages I removed (I removed those tag pages that were near identical to the category pages, I left the unique tags). Panda obviously liked that, but Bing didn't!
Just goes to show what a PITA it is trying to rank for two search engines. Thank goodness all those minor search engines have no chance of taking off - can you imagine the nightmare trying to deal with multiple algos?
Not too fussed about the loss of Bing traffic (even though it converted well) as it was a fraction of the G traffic in any case. But am going to have to rack my brains on how to get ranked better on Bing without upsetting Google, just in case Bing market share increases.
P.S. It's obvious why I dropped in Bing - loss of links (internal in this case). But Google is acting like those tag pages made no difference in terms of link juice, because I'm ranking where I was. Isn't that interesting?
P.P.S. Just seen on the Bing forum that there was a Bing algo update. So adding content and deleting tags is something the new Bing algo doesn't like. Unless there is something else going on in the Bing algo. (Apologies to the mods for talking Bing on a google thread. Will stop now).
