Bjorn Enki has posted a tool which allows publishers to preview how a site might potentially appear in the Google SERPs. The tool prompts you for a bit of site information including:
  • Title
  • Meta Description
  • URL

Once you've entered the essentials, you have a chance to play around with a few appearance modifiers:
  • Decide what words to bold.
  • Show the date?
  • PDF preview option?
  • View Post/Author/Last?
