All of my sites dropped.What are the remedies?

I have 12 sites.All are addon domains.I created high pr blacklicks for them.And all of them was first page in google SERPs.15 days ago I gave 250 links for all sites with automated software.That means I created about 3000 links for 12 sites.Yesterday I saw that all of my sites dropped and they are now 10th to 60th page of the SERPs of their keywords.What can I do now at this condition?

My adsense earning dropped to zero.What can I do now?I did not ad any content to my sites.I only created one page websites.All of my sties are one page websites.and I didnot agree to ad content.What is the remedy of this situation?

Any suggestion or help?Any body here face same type of problem and overcome this?How can I overcome this problem?

 

Seems like you too have been punished by Google Panda. Did you have some 'unique content' in your one page websites ?

 

one domain goes, all the addon domains go with it. Why were they on the same domain?!

 

yes I have unique content on my websites

 

I did not know that if one sites of the domain goes all of addon domains go with it.Is it true?

 

Found many reasons.. bulk link building by tool may be a reason.. also ur sites are single paged with poor content.. so like those sites will not get stabled ranking

 

Fully agree. Add to that the fact that after the new Panda update Google will very closely review the quality of the sites - and one-page sites are likely to fall in what Google calls "shallow content".

Try adding quality content to all those sites, I'd recommend at least 10 pages. (BTW, make sure that the sites are NOT cross-linked). Check also things like grammar and spelling, Panda considers those as I highlighted in my blog. And do NEVER again create mass links!

 

google loves manually natural link building, they punish automated submission

 

before few years back one content is enough to rank on first page but now a days it is getting harder to rank with one article.
