To stay on top of that, you need to keep up with your Webmaster Tools and Analytics, both provided by Google. The downside to this is that they can be overwhelming or difficult to decipher if you’re not familiar with it. Then again, if you’re aren’t sure what you’re doing within Webmaster Tools or Analytics, you could get into a bit of trouble and harm your site in the process.
The good news is that there is an easier solution. Moz (moz.com) has just released Spam Score. Spam Score is a new metric available to Moz subscribers that can let you know when your site might be at risk at receiving a penalty from Google. I don’t have all the details on how it works, so it’s best to let Moz let you know what it’s all about.
