With the Spam Score feature, users can assess the risk of penalties associated with their domains. This proprietary metric from Moz helps identify potentially harmful backlinks before they affect your site's authority, making it a vital tool for link-building strategies.

The Backlinks Analysis feature provides comprehensive insights into the total number of backlinks, as well as the ratio of dofollow to nofollow links. Users can see referring domains for any site, enabling them to understand their link profile and improve their SEO efforts.

Keyword Difficulty

Keyword Difficulty estimates how competitive it is to rank for specific keywords. This feature is essential for content strategists looking to invest in effective SEO content that can drive traffic and enhance visibility in search engine results.

Organic Keyword Opportunities

Uncover high-potential, low-competition keywords you're not yet targeting, all within the context of your paid campaign data.
