We have used Google disavow tool to reduce the effect of bad links that we are unable to remove for our several websites. but haven't seen the significant impact on the websites listing yet, Though couple of accounts, which were affected with Google manual penalty have become free.
So would like to know whether to disavow the links give impact to only manual penalized websites? or anyone that has got notable improvements in their listing and traffic after submitting the doubtful bad links in disavow tool. and how speedy the positive response of disavow?
This is one of the brain storming queries that have been raised in many webmaster's mind, when Penguin impact is high.
