Google replied to say: follow the webmaster guide again. Then I realized that the only other thing that I did was link building. And that is almost impossible to reverse.
My Adsense account is still active and making money from people going back to some of my websites, but other wise it is gone.
The way Google found all my websites in one go (I think), was that I listed in Adsense all the websites I want to earn money from under the 'account settings/access and authorization' section. My websites that I forgot to add to adsense access and authorization section was not de-indexed although I have custom adsense channels for them.
I want to warn you that please don't let this happen to you. Do not use link building strategies that put your business at risk and don't make for adsense websites. Google can easily spot them.
I need to start all over again. 18 months of adsense work is gone, but better now than later.
The only 'safe' link building seems to be the following:
1. Guest blogging and article syndication
2. Directory submissions
3. Very moderate social bookmarking
4. Handful of profiles that are actual contributing in forums
5. blog commenting
6. Please let me know of more ways...
And rather make good quality websites. With Google +1 and reporting of spammy websites to Google, Google is going to clean the index fast.
Now that I look at all the offers on WF, I am worried for all the people using these link building packages. It is very high risk and you cannot build a online business like that. Google will shoot you down in one go if they find you.
I would like to know what your thoughts are on link building penalties by Google and how you are building links the real white hat way?
