Im Coming from a Famous Organization based out in United States.
We' used to have a team before 1 year who actually performed lots of directory and bookmarking submission and we have gained around 1 million backlinks from them
After Google penguin 2.0 update our site ranking went to 3rd page because of this bad backlinks.
WE WANT TO USE DISAVOW Tool
but we are afraid whether using this tool will show adverse affects and still drop our rankings and we REALLY CANT BEAR THAT !
If someone have used GOOGLE DISAVOW TOOL and worked Please Kindly let us know if this would really work or not ???
