The domain cal.com was registered on May 16, 1997, through godaddy.com, llc and uses Cloudflare for DNS and security. At 28 years old, the domain benefits from established credibility, a mature online presence, and accumulated authority that contribute to stronger trust signals and long-term SEO advantages like higher domain authority and sustained organic visibility.
Cal.com’s backlink profile shows a mix of mostly medium-authority (DA 40-69) referring sites with a few high-authority (DA 70+) placements (notably a DA 73 Indie Hackers mention) alongside links from technology publications, developer resources, and industry leaders, indicating a generally respectable but uneven quality distribution. This blend of referring domains supports Cal.com’s organic visibility by providing topical relevance and citation signals from niche and broader outlets, bolstering its overall SEO strength despite room to grow in acquiring more consistent high-authority placements.
The top-link sample shows an approximate 90:10 dofollow-to-nofollow split (1 dofollow vs 9 nofollow), so while most links are nofollow the few dofollow links from higher-DA sources can meaningfully pass link equity and help authority. Anchor text is overwhelmingly branded/naked with an estimated Branded: 90%, Naked URLs: 10%, Keyword-rich: 0%, Other: 0%, which is largely natural and safe for Cal.com’s profile but could benefit from a small, strategic increase in descriptive keyword anchors for topical relevance.

Cal.com is built on a modern frontend stack that combines React with Next.js to deliver fast, component-driven interfaces and server-side rendering for improved initial load performance and optimal SEO, while legacy helpers like jQuery and animation tooling like GSAP provide DOM utilities and high-performance animations where needed, enhancing developer productivity and user-perceived responsiveness. This frontend is paired with a robust backend and delivery layer using Amazon EC2 for core hosting, nginx as the web server, Cloudflare for CDN and edge optimizations, and Vercel for serverless deployment patterns, collectively enabling reliability, scalability, and global distribution through edge caching and dynamic serverless functions.
The security and DNS layer leverages LetsEncrypt for TLS, HSTS for strict transport security, Cloudflare SSL and edge services for DDoS mitigation and accelerated content delivery, and Azure Active Directory for enterprise-grade identity and single sign-on, providing strong encryption, DNS protection, and consistently fast load times across geographic regions. Observability and product analytics are covered by tools like Google Analytics, Google Tag Manager, Sentry, and FullStory, which together improve monitoring, error tracking, and user experience insights to inform faster development cycles and data-driven UX improvements.
