Over the weekend something happened at Google. Maybe speculated it was a Panda update but after reaching out to Google, Google told us there was no Panda update.
We then asked them if it was one of the other updates if it wasn't a Panda update? Maybe Penguin or EMD, page layout or something else. Google wouldn't say, they did say their standard comment:
We make over 500 improvements to Google Search each year so we can surface high-quality information for our users.
But Google did give us one nugget. Google told us a Panda refresh will likely happen within 7 to 10 days, if all goes on according to plan.
