Show HN: Geo-lint – open-source linter for GEO (AI search visibility) (github.com)

A new open-source tool called Geo-lint has been launched, designed to optimize content for AI search visibility by implementing Generative Engine Optimization (GEO). Unlike traditional SEO tools, Geo-lint provides a deterministic way to validate content against specific rules crucial for inclusion in AI-generated answers from platforms like ChatGPT and Google AI. This linter automates the process of checking content quality and format with 92 rules—35 focusing on GEO and the remaining on SEO and content quality—ensuring that content is not only found but effectively cited in AI responses. The significance of Geo-lint lies in its potential to bridge the gap between content creation and AI search relevance, particularly as generative AI becomes integral to online information retrieval. Users can set up the tool to automatically run checks on their content, receive notifications for issues, and allow AI agents to make corrections iteratively, leading to cleaner, more AI-friendly content. This innovation represents a substantial advancement for content-heavy websites looking to enhance their visibility and citation in an era increasingly dominated by AI-driven search engines.
