Nodelix

South Korea-based, Nodelix works with clients across specific verticals rather than as a generalist agency: hospitals and clinics, financial and insurance services, law firms, tax and accounting practices, academies, community and forum platforms, and general brand websites. Each of these sectors gets a dedicated approach on the agency's site, reflecting different search intent and competitive conditions — for example, YMYL-focused trust signals for finance, local SEO and E-E-A-T credibility building for hospitals, and location-based content for tax and accounting offices. The team is small (1-10 people) and positions its work around technical, algorithm-driven search engine optimization rather than general marketing. The core service set covers search engine optimization (on-page and off-page, with industry-specific strategy), backlink building from sites with a minimum domain authority of 40, and SEO-first website construction that incorporates Core Web Vitals optimization, schema.org structured data, and semantic HTML5 from the design stage. Nodelix also offers AEO (Answer Engine Optimization) and GEO services aimed at getting brands cited by AI search tools such as ChatGPT Search, Perplexity, Google AI Overviews, and Microsoft Copilot, including structured-data generation intended for AI citation. Its technical process draws on a self-developed analysis engine for keyword tracking, ranking, and competitor analysis, alongside the Ahrefs API for backlink monitoring and toxic-link detection, and direct integration with Google Search Console and GA4 for auditing site performance. Additional listed services include page-speed optimization, marketing strategy and data-driven analysis, and DDoS protection solutions.
