The first thing that we tell them is to stop responding to the Blogs or forums that they are being attacked on. Once you start responding and going back and forth with the Blogger, the search engines start classifying it as good, fresh content, and they will not only keep the placement there but it will most likely raise the placement a bit. The best think you can do is to not respond to the comments, and let the search engine lose interest in the page and allow it to slowly remove it from the listings.

If you are impatient about the listing being there, you can hire a good SEO firm to create ?good? news about your company that will replace the bad. This is costly, but it does work.
