my sites completely disappeared from Google

[masai]

Hi,
I'm the webmaster of 6 italian sites about lists of addresses (list of professions, list of shops, list of restaurants, etc). One of this site is www.cerca-in-internet.com

From june to the half of september, I had near 10.000 pages viewed, and near 100$ a day from adsense.
In september 16, ALL the pages indexed on google disappeared (all the same day!!), and now pages viewed are only 100-200 a day.

Anyone could explain me WHAT'S HAPPENS??

Thank you
Massimo

I am seeing 6130 of your pages in the Google index, though they may not be visible for the results that you have been seeing. That would indicate that you haven't been dropped, only dropped out of place in the index. However, they are only giving you credit for one incoming link. I'd guess that has changed because with only one incoming link credit, it's hard to figure out where you were doing 10K pages per day. MSN gives you 324 and Yahoo gives over 18,000. Obviously Google doesn't think so much of your linking methods.

I'd guess you either got caught in some sort of filter or link spam trap and are being penalized. Rather hard for me to wade through the Italian though so while it looks as though most of your links are coming from your own sites, I could be wrong. If you got the kind of traffic and Page Rank you have by merely trading incoming links between your 6 sites, you could be tripping over yourself and you could expect to see this with other sites that are doing similarly.

There also could have been some kind of blip in the Google index though I doubt it. If there is, you should be back in a few days. While waiting, look to see if you have changed anything dramatically in the last month or so that Google might not have liked, and undo it. Also check other outgoing links to see if you might have started linking to a bad neighborhood and are thereby associated with it. These are things that could have caused you problems.

If all of your links are between sites, your problems are just beginning. Matt Cutts made the statement here a few months ago that they were also looking at 3rd party link systems and eliminating the effect from these. If you are using the same host and are on the same IP C block, this can also point to the fact that linking from one site to the next is part of a linking scheme by the same owner from site to site.

Thank you Papadoc,
I think I need more and more GOOD incoming links

Hate to say it but maybe it is because these websites are MFA (Made For AdSense) and really provide no real information tot your end visitors. AdSense wasn't made to replace content on website, it is simply advertising to compliment your current content on your website.

Google probably caught onto this and your not ranking as high as before. I am sure their is more to it than this, but it would require some research.

Agree with IH on the MFA thing, and from *Results 31 - 34 of about 39,800 for "www.cerca-in-internet.com"* I'd suspect your links have been devalued...
