The MozBar Chrome extension offers greater insight into the SERPs and on-page SEO. The free version will show you the page and domain authority, allow you to explore links on the page and reveal the meta information for the page. You need to be logged into your Moz account for this extension to work.
To use the MozBar, you can click once on the icon to reveal the MozBar. There are three main menus; page analysis, highlight links and page optimisation. Use this to explore the page content, meta information, link metrics and markup.
Click again and the MozBar will disappear and you will enter DA mode, or domain authority mode. When you navigate to a new site, the DA will be shown in the middle of the icon. This is helpful for link building and understanding changes to your own website.
MozBar is excellent for those getting to grips with SEO as it introduces some key elements that you might see mentioned in a report.
