I would also wonder if I'm alone in having a worst ever month.
You are definitely not on your own and by the stickies I have had this thread may fill-up very fast!
I know some people, who were doing ok whilst I was being knocked back again and again, are now experiencing the same as me and just wondering whether ANY of the effort is now worthwhile since no matter what I/we do it simply gets worse and worse.
I know why I've lost traffic, it's all to do with scrapers, image theft and Google's new image SERPs, and Bing for that matter, but quite why some people have been stuffed after so many successful years is perplexing in the very least.
I don't post much here these days since it's, quite simply, pointless for me, the SERPs have been Google-rigged and that's the way they're going to stay and get even worse for many of us.
Google's scraping a massive amount of money, some will be lucky enough to get to feed at that table but don't bet on an extended invitation...YMMV!
