I'm a relatively new seller. Went hard at PPC out of the gates with high bids and ranked at the top of the page for at least 75% of the keywords I bid. Within the last 24 hours I've noticed that no matter what I bid, my ad is no longer show at the top and instead appears at the top of the side bar and/or the bottom of the first page as a sponsored ad. I read about changes back in February. I've seen sellers claim PPC is now junk. So...is this the junk people refer to? Anyone recover? Did I get some sort of grace period to prove myself as a new seller and didn't pull enough sales resulting in an algorithmic slap-down?
