I'm seeing unusual shifts in rankings for many info/affiliate websites (some of them are 4-5 months old, while other ones are 1+ year old). Basically their main keywords are suddenly disappearing from Google entirely - they can't be found anywhere in the Top 500. Then, 30-60 minutes later, they are back where they were (top 3 of 1st page) for 5-10 minutes, and then disappear again. These are not "thin" sites by the way, rather very informative and well-structured.
This has been going on for 2 days now for at least 15 different websites that I'm monitoring, including one of my own sites. Anyone noticing similar behavior?
