While rich snippets are generated algorithmically, we do reserve the right to take manual action (e.g., disable rich snippets for a specific site) in cases where we see abuse, deception, or other actions that hurt the search experience for our users. In particular, you should avoid:
Marking up content that is in no way visible to users.
Marking up irrelevant or misleading content, such as fake reviews or content unrelated to the focus of a page.
These quality guidelines cover the most common forms of deceptive or manipulative rich snippet behavior, but Google may respond negatively to other misleading practices not listed here. It's not safe to assume that Google approves of a specific deceptive technique just because it isn't included on this page. We strongly advise that webmasters focus on providing a great user experience rather than on looking for loopholes.
