I think I finally found what is Panda after and how and when it works. I know my English is not perfect, but read the following in the next few minutes.
- some people reported getting their traffic down about 60-95% at some sort of Panda update (let's say it Panda X). The same people reported getting the traffic back at the next Panda iteration (let's say it Panda X+1). The same people reported getting their traffic cut or down again at the next Panda iteration (let's say it Panda x+2). Why is that, really? The answer is simple - Panda X cut your traffic because your content was not useful for your user. Panda X+1 got you back because Google Panda wanted to know if you changed or made your content useful for the user. If you haven't made your content useful for the user, then Panda X+2 will cut you again and probably Panda x+3 will bring you back or not. How does my logic sound?
- my theory is based on the fact that, let's say I have one website that has a lot of pages, but most of them don't give my searcher what he or she wants. At one Panda iteration Google will penalize my website, but it needs to know if I'm willing to make the content better or not. It doesn't care about grammar or links, but if my content is useful to the user (Google's bounce rate matters, not yours). I mean, let's say I look for "widget" and I have the intention to buy it. I wouldn't spend to much time on an informational website, but spend the most of the time on the website I want to buy on. I might even block that informational website, because it might not be there.
So it's simple, Panda cuts you down and then let's you improve your website. It might put your rankings back for a while to see if you improved your content and then back you down if you haven't. So if you have been hit by Panda once and you haven't recovered yet, you might, but in the period you are up don't think your content is good enough. It might not be as good as you think and if your users don't think your content is good enough, they will block or ignore your content, then at the next Panda iteration Google will put you back in the list.
Now, how can we improve our content?
- having or not breadcrumbs doesn't matter or influence the Panda update. I saw damaged websites with breadcrumbs and without breadcrumbs so it doesn't matter.
- nofollow external links it doesn't matter. I saw damaged websites with nofollow external links (all) and websites that got higher in rankings with nofollow external links.
- blogspot, knol and facebook rank higher than ever after this update, but I don't know how much.
- Mahalo wasn't hit by the latest Panda updates and Infobarrel is up in rankings, so they must be doing something right, even so they are content farms. On another hand Ehow and Suite101 are way way down, along with articlesbase. They are content farms already, so there is no reason they wouldn't be down.
- I don't think the number of Google ads is the reason to this update, neither the grammar and spelling. Not yet.
- I do think the way the information is presented on the website page matters, not that the Google bot understands it, but the humans read it or not according to the way it's presented on the page.
The only thing that we can do to avoid Panda in the future is to improve our website content as fast as possible and don't stop until 2-3 Panda passed our website and it's good and ranking. Ideas?
