MozBar

MozBar is Moz's SEO toolbar for Chrome, rebuilt for version 5, that shows metrics as you move around the web. On landing on a page it reports Domain Authority, Page Authority and a Brand Authority score. An on-page highlighter sorts links into followed, nofollow, external and internal so they can be spotted at a glance, and on-page elements and general details are listed for review. It suits both competitive research and a technical audit. Access comes in levels: guest mode covers on-page elements, general details and internal link information, a free account adds the authority metrics, and Moz Pro subscribers unlock Spam Score, Page Optimization, Domain Analysis and Keyword Ranking queries. Results are cached for 48 hours to save query allowance, and the toolbar can be docked to different edges of the window.
