As we know a number of quality sites got hit by Panda, baby out with bath water. Which is very annoying
Meanwhile, we see the rise of the old doorway pages making great ground.
So now you see a page about "blue widgets" with detailed analysis that the adsense reps pushed the webmasters to carry more adsense on, getting well and truely hit and demoted in the index.
And at the same time some junk sites writing a page of keyword text about "blue widgets" with a link to "See your blue widget results here" that points to a page full of adsense results storming up the index.
Meanwhile, those quality sites reducing adsense and in general tidying up their sites to fall in line with the additional new criteria and google guidelines fall into the various other google re-index filters and are still nowhere to be seen / demoted.
If they are going to be this ruthless with the index you would think that there would be some respite for responsible webmasters trying to react and do the right thing?.
When you have invested significant years building a great site its sickening to see junk sites ranking above you, with old black hat tricks, because google now deems your site as poor quality and there is nothing you can do about it.
Couldn't put it better RichTC. I am devastated by this update. Like you said "So now you see a page about "blue widgets" with detailed analysis that the adsense reps pushed the webmasters to carry more adsense on, getting well and truly hit and demoted in the index."
Same case here, I had a super popular site on "blue widgets" I get mails from Adsense that I am not monetizing my site I place the ads where the Adsense Team recommended me and then bang I am out of first 5 pages and junk ranking on top.
This update has killed so many great sites and they just won't admit it. As Aaron puts it on his new blog Google will soon be a paid inclusion type search engine that is if you want visitors, as most of your screen will be packed by Local Ads, Adword Ads on top and such.
In regards with doorway pages and junk sites I think they are all owned by some Google Employee that they are not being hit at all.
