The most effective way to counteract bad online reviews is to continuously (and regularly) add valuable content to your website so that, in time, your current content will override the negative reviews that are appearing in keyword searches, essentially nudging them down the list.
Search engines give preference to websites that are continuously updated with current content that is valuable to clients or customers.
The most important word here is content, content, content, and the second most important word here is current, current, current.
Direct your content to the specific keyword searches that are resulting in negative results, so that the new information that you provide will compete with the negative comments.
Publishing positive client testimonials (regularly updated as well) from actual clients to a prominent place on your website is not a bad idea either.
Consistently treating all your clients with courtesy, consideration and care will also go a long way toward counteracting negative posts. Treat each client as if they were your brother or sister, and you will soon develop a positive online reputation.
Providing quality service — consistently — will also give you an edge against negative search results.
