What tool can I use to evaluate the domain authority of a competitor?

Hi Derick. https://moz.com/researchtools/ose/comparisons is great for back of the envelope calculations as is the Moz toolbar.  If you want to get really in-depth you'll likely want to run some full reports, export, and go through the data in a spreadsheet.

The http://moz.com/labs/link-finder Competitve Link Finder is also nice for seeing areas to gain lift that your competitors have already found.

Derrick,

"Domain authority" is pretty much a term that Moz coined back around 1995 as an alternative to Google's term "pagerank". Essentially the two describe the same thing and Moz's tools evolved since then as a means to quantify the factors that make up pagerank/authority.  Moz's  tools are a good place to start wrapping your arms around the strength of a competitor's site as compared to yours.
