You don’t need to worry we are having experience in handling these type of Reputation management Campaigns.
WE have worked with Few Irish Companies, Clients.
This is the straight forward Plan to handle these types of problems.
Their are 200+ Social media (Renowned) , web Properties where we can create Free Profiles , we can add article / Content about that specific keyword you want results to bury to 7-8th page in Search Engine . after building these properties , Blogs, articles , we need to do White hat ( Niche Link Building to keep them on Top & your undesired results will be bury in 8-10th pages even further.
Don’t use black hat on unwanted Result as this is not permanent Solution.
I am confirmed when you doing Black hat, in next Google Algorithm Update your undesired results will be again on Top with Penguin, Panda, Update.
Have a Look @ the Plan & let us know if you have any Further Questions.
