Hi there, Jo from the Help Team here. Moz's Spam Score is the percentage of sites with similar features we've found to be penalized or banned by Google.

You can then look at your site and investigate areas you would like to improve on your site: https://moz.com/help/link-explorer/link-building/spam-score Best of luck! Jo
