The domain respondent.io was registered on March 7, 2016, through namecheap, inc. and uses AWS for DNS and security. At 10 years old, the domain benefits from established credibility, a mature online presence, a proven track record, and accumulated authority that can strengthen trust signals, backlink profiles, and SEO performance.
Overall, Respondent.io’s backlink set is largely coming from lower-authority referring pages (many top links show DA 20-23, which falls below the medium range) while the domain-level metrics (listed DA 48/68) indicate a medium-authority site; notable placements include industry leaders like Forbes and developer-focused properties such as the GitHub Blog, alongside a lot of mentions in technology publications and developer resources. This broad but lower-DA link footprint—combined with a large volume of backlinks and thousands of referring domains—supports solid organic visibility, though the limited number of truly high-authority (DA 70+) referring domains constrains the maximum SEO lift those links can provide.
The sample shows a dofollow-to-nofollow split of about 40:60 (dofollow:nofollow), a tilt toward nofollow, but the presence of dofollow links from notable outlets means those links still pass valuable link equity when they come from stronger sources. Anchor text is heavily branded with approximately Branded 80%, Naked URLs 10%, and Keyword-rich 10%, which is generally a natural and safe profile (strong brand signals) but could benefit from more diversified, authoritative keyword-rich anchors to better target priority terms.
