Ok so after a lot of work, I had around 10 keywords ranking well, including a couple of high volume searches. Then Penguin 4.0 comes along and all my keywords except two disappear out of the top 300 results. Fine i guess its an update and my attempts at link building are best described as amateur so i probably deserved it but then they started to re-appear then disappear again. After a week it settled down and my keywords stayed gone, i accepted my failure and moved on, then this morning out of no where they were all back and not just back in the results but back to where they ranking before the update, I was over joyed, 4 hours later they were gone again. I can't take it anymore Does any one out there have any ideas why google is so indecisive.
