It was a big deal to businesses last year when Google's Questions and Answers surfaced in the news. We are not aware of a credible algorithm that currently handles spam questions and answers adequately. No one quickly lines up for the task of sorting through spam reviews in our experience. At the same time, it is important to respond to all business Q&A’s, especially if someone flags it. A credible spam algorithm is present because Google is watching to find answers worth sourcing. Prior to launching, a body of Google TC’s expressed concern regarding the open door this may create for Spam together with the struggle that business owners may face to moderate the Questions & Answers on their own. Who wants to face having a “ red flag” a wrong or spammy question or answer show and be attributed to them. Google reviewers are check for accuracy; so should you.
