Randfish of SEOSurvey has a new version of a tool that helps determine if your site is stuck in the Google sandbox. He admits that the tool is not authoritative, but uses many factors to pinpoint the likelihood of being in the sandbox. Indeed, it does seem to be a fairly extensive test, and while it seems to be fairly accurate, keep in mind that it is only an educated guess. Since there is no definitive proof that the sandbox even exists, and many SEOs would argue that it does not exist, use this tool as a general guide and draw your own conclusions. Even if the test is inconclusive, it still gives great insight into how your site stacks up against the competiton. And that is information that is always useful to the SEO.
