Why were all of my Amazon sites deindexed?

[leetk3zzer]

March 22nd.. The worst day of my Internet Marketing career. I got the dreaded message:

Dear site owner or webmaster of http://www.ricecookerreviewz.com/

We've detected that some of your site's pages may be using techniques that are outside Google's Webmaster Guidelines. If you have any questions about how to resolve this issue, please see our Webmaster Help Forum for support.

Here's some interesting points:

• All of the content is unique and highly targeted to each product.
• Site is around 4-5 months old
• Every single one of my Amazon sites were hit.. How did they connect my sites together..?
• Why were they hit?

List of some of my deindexed sites:

http://www.inversiontablereviewshq.net/

http://www.breadmachinereviewshq.net/

http://www.ricecookerreviewz.com/

http://www.cooker-reviews.com/

http://www.ab-machine-reviews.net/

They are most definitely not, "thin affiliate sites". They have dozens of reviews, tons of articles, recipes, video.. Each site is like this..

I have started over, fresh content from my writers, fresh theme, fresh everything. But still, I would appreciate an answer as to what I'm doing wrong so that I can learn to not make the same mistake.

Thanks!

Hi,

I've setup 301 redirects on cookerreviews. Check one of the other domains, e.g. breadmachinereviews.

I agree with ABK717.

Why every time a user clicks on http://www.cookerreviews.net/ they get redirected to http://www.slowcookerworld.com/ or another website?

A simple HTTP head review to http://www.cookerreviews.net/ returns HTTP 1.1/ 200 OK. This means it shouldnt redirect, but it does anyway.

Thats the first thing I see. Obviously Google will not like this.

You will need to host your page on one domain. You dont need the other domains, especially that exact match domain optimisation doesnt carry as much weight as it used to in the past.

I hope this helps

In glancing quickly at your first site, I see that Google isn't indexing it nor are any inbound links found. You need to have legitimate links pointing to the domain, not spammy links, to give it some creditability. If you get too many links too fast, this can also hurt you.

In regards to "How did they connect my sites together..?", Google has its own domain registrar which can see who owns what sites.

Hope this helps.
