bring my post on top

Hi everyone here,
I am into seo,and i am facing a difficulty,when i type a keyword for my website ,my website comes on top but there is one negative post that appears on 4th rank on first page i want to lower that post,so i created many social networking sites with same keyword and trying to make them come on first page but they are not coming.th negative post is from wellknown online news so they have more number of backlinks and don't find any whitehat way to lower the negative post.So i want to know various black hat techniques that i can use to reduce the rankings of that negative post.Thanks

Invest in power seo that says sweep away negative reviews .. they ll bring up some positive reviews so that the negative one might almost dissappear

You just need to do some more SEO on your other sites so that they rank above that page. Maybe look into some of the services here in the forum.

guess that will require combination of SEO + ORM!

thanks a lot but i am already doing this thing from last 30 days.but didnt show much results...the negative post being from a wellknown news website is being updated regulary and have large amount of backlinks,arw there any other ways of solving this issue?
