duolingo.com traffic, backlinks, authority, and more

The site's traffic has declined by 4% year-over-year with over 2,145,260 monthly visits driven primarily by interest in language learning fundamentals, grammar contrasts, common phrases and translations, vocabulary/synonym searches, alphabet basics and test/prep queries. Traffic is concentrated in North America (~33.6%), Asia‑Pacific (~29.9%) and Europe (~23.6%), reflecting strong demand in the platform’s key English/Spanish/Portuguese-speaking markets and broad adoption across APAC and European language‑learning audiences—important signals for market prioritization and localized product investment.

The domain duolingo.com was registered on January 26, 2010, through amazon registrar, inc. and uses AWS for DNS and security. At 16 years old, the domain benefits from established credibility, a mature online presence, and accumulated authority, which translate into stronger trust signals, higher search visibility, and long-term SEO advantages due to its proven track record.

Duolingo’s backlink profile shows a strong mix of mostly high-authority links (site-level Domain Authority 81/79 and several top links at DA 80+) alongside a healthy number of medium-authority referrals (DA 40–69) from notable sources like Wikipedia, GitHub, and a prominent CAPTCHA provider — indicating placements in technology publications, developer resources, and among industry leaders. This distribution of authoritative, trust-worthy referring domains amplifies Duolingo’s organic visibility by passing substantial topical relevance and trust signals, bolstering its overall SEO strength and ability to rank for competitive keywords.

The top-link sample shows a dofollow-to-nofollow split of approximately 80:20, a dofollow-heavy distribution where dofollow links from high-authority sources are positioned to pass meaningful link equity and domain trust. Anchor text is dominated by naked URLs (50%), with branded anchors (30%) and keyword-rich anchors (20%), a balanced mix that looks natural and healthy for Duolingo but should be monitored to ensure keyword-rich anchors remain a minority to avoid over-optimization.

Duolingo's scores reflect a strong authority, high trust, and a high-quality backlink profile, indicating excellent overall SEO health that enables top search visibility, resilience to algorithm shifts, easier ranking for competitive keywords, and a market-leading competitive position while still requiring ongoing content and technical investment to defensibly maintain that advantage.

The domain duolingo.com has a broad keyword portfolio centered on language education and branded navigational queries, combining high-volume generic terms like 1,830,000 searches for "language learning" with strong branded and misspelled query coverage that together reflect wide topical reach and clear user intent capture. The top keyword 'language learning' attracts daily searches in the tens of thousands with a $3.22 CPC, indicating strong commercial value. The other keywords — "duolingo login" (60,500, 0% competition), "doulingo" (40,500, 2% competition), "duolingo english test" (27,100, 4% competition), and "dulingo" (18,100, 2% competition) — show consistently low competition levels, signaling dominant branded SERP ownership, high user intent for account/access and testing offerings, and limited paid bidding pressure from rivals. The domain's strengths are clear: strong organic visibility, healthy keyword portfolio, and competitive SEO performance.

duolingo.com is built on a modern frontend stack that combines React with legacy helpers like jQuery and a bundler such as Webpack, giving the site component-driven rendering, modular assets, faster client-side updates, and improved developer experience; together these tools enable patterns that support server-side rendering and optimal SEO while keeping runtime payloads efficient. On the backend the site runs on Amazon EC2 infrastructure fronted by Cloudflare Hosting and served through nginx, a combination that provides high availability, caching at the edge, and reliability and scalability for global distribution of content.

The security and DNS layer leverages reCAPTCHA, Amazon WAF Blocked, and WebAuthn to mitigate bots, block web exploits, and enable strong authentication, contributing to DDoS protection and fast load times via secured routing and CDN-level defenses. Observability and product tooling include Google Analytics 4, Google Tag Manager, Mixpanel, and FullStory, which together improve developer and product workflows by providing user insights, session replay and performance monitoring to iterate on UX and maintain high-quality experiences.

duolingo.com competes in the online language learning and education space against established players like Busuu, Babbel, and Preply, and newer alternatives such as Duome and Memrise.

With a Domain Authority score of 81, duolingo.com sits on par with its main industry peers in the online language learning market (the competitive set in the table all report DA 81), so differentiation is less about raw authority and more about traffic, product, and distribution. Duolingo’s focus on gamification, free tier accessibility, and bite-sized mobile-first lessons targets a large, mainstream audience and has produced strong organic visibility and rapid market penetration, translating into higher user acquisition and sustained growth compared with more traditional subscription-first competitors.
