The problem is more serious, where you're going along on the first page for months at a time, in various positions, then one day you wake up and you're on page 4.
Agree with this. It would be more prudent on Google's part to sort of gradually drop you down over a period of time so that you could realize that something is up and start to work on fixing it before you go from 60 to 0.
Ruining lives without explanation is unacceptable behaviour on Google's part
Yeah, but we must assume that no corporation is going to act in our best interests. About 10 years ago i was emailing back and forth with a former colleague who was bragging about how her online marketing for a software company was working so well ... and all their sales came from AdWords PPC. My reply was, if 100% of my revenue came from google i would be terrified (adwords, organic, whatever). I already get 60% of my traffic from them and it scares me to death. What if they just turn me off one day. She didn't reply at all to that.
I constantly try to diversify my traffic sources. Maybe it helps in that when Panda hit my sites I only lost 25% of traffic rather than 80% like some people describe. But it's always your job to plan for a rainy day ... or an unreliable partner...Sure online as far as search goes, it's not easy to rid yourself of google, but it still is a viable objective. I think the end result is that web developers are going to learn they can't create a world that is spelled google, google, google and expect to comfortably thrive in it. In the end google is forcing us to give Bing, Facebook and whatever else we can find, a much greater chunk of our time and effort.
Back on the topic. I posted in another thread
here [webmasterworld.com] that one of my sites lost a lot of traffic over the last two weeks and it seems that a big drop came on Oct 13-14. So I assume it's Panda 2.5. Since I have 4 other sites that have many SEO things done in the same way, and only one got hit, I have a pretty good test bed to see what's really going on.
The research I've done indicates, as before, that Panda is all about onsite factors. It's been written on some other SEO sites that Panda 2.5 is about meta tags. Specifically, if what is in the meta is not on the page, you will have problems. So that may explain the losing or finding of long-tail keywords.
The only other factor that applies to my Panda 2.5 affected site that is not present on my other unaffected sites, is about 10 times more article marketing back links. Specifically, all of the affected keywords are used in article marketing "all in link text". So in this case for my 2 pages that took a -50 hit, we're talking about maybe 200 back links that all use 3-4 word combinations of the same 4 keywords. But those same pages are also in the most competitive niche. I'm really sceptical about whether this alone could cause a penalty, because if that were the case, I could downgrade anybody's site by writing 5-10 articles that all use the same link text, get them syndicated across 10-20 sites each, then watch the guy fall.
Does anybody else have similar experiences or thoughts on what onsite factors are targeted in this update?
