On Friday I reported at Search Engine Land that Google will no longer give us confirmations or more details on future Panda updates.
Why? Google no longer plans to push out manual Panda refreshes, all future ones should be part of Google's rolling updates. So Google told us at Search Engine Land:
I don't expect us to tweet about or confirm current or future Panda updates because they'll be incorporated into our indexing process and thus be more gradual.
Honestly, I prefer it that way. There is so much stress for me to get Google to respond and give confirmations on these updates. I feel it on both ends. You guys, the SEOs and Webmasters want the confirmation. Google is not always eager to give them to me.
So now, with Panda, I won't have to worry about it anymore.
For Webmasters not knowing is never good but if it is part of Google's rolling updates, if you believe that, then there is nothing they can do to really help you there.
