MozBar is a free extension for the Chrome browser (requires free account registration).
You can use it to find statistics about the website you’re currently visiting such as the Moz Page Authority, Moz Domain Authority, number of backlinks, and social statistics.
Page analysis is also available to help you find meta data, page load time, markup, and more. You can even highlight text or specific link types such as followed, no-followed, external, etc.
Additional insights are available with a paid subscription to Moz.
