The domain duo.com was registered on October 14, 1998, through markmonitor, inc. and uses AWS for DNS and security. At 27 years old, the domain benefits from established credibility, a mature online presence, a proven track record and accumulated authority, which collectively strengthen trust signals, backlink profiles, and long-term SEO performance.
The backlink profile for Duo shows a mix of mostly medium-authority (DA 40-69) links with a significant number of lower-authority referrals (many sources in the DA <40 range) and few if any true DA 70+ authorities; notable sources include technology publications and developer resources such as Krebs on Security and Cisco Community even though those specific links are lower-DA or nofollow. This distribution, combined with a high volume of referring domains (16,124) and a solid trust score, contributes positively to Duo’s organic visibility by providing topical relevance and citation breadth that strengthens overall SEO strength.
The sample set shows an approximately 50:50 dofollow:nofollow distribution (5 dofollow vs 5 nofollow in the provided links), a balanced distribution where dofollow links from the higher-DA sources (e.g., DA ~61 and DA ~68) are positioned to pass meaningful link equity to Duo. Anchor text is skewed toward branded and naked forms with approximately 50% branded (e.g., "Duo", "Duo Security"), 40% naked URLs (e.g., "duo.com"), and 10% other (non-branded or generic), with minimal keyword-rich anchors — a profile that appears largely natural and healthy but should be monitored to avoid over-reliance on branded anchors.
