Latency Optimization: Work on data structure and flows to ensure near-instantaneous AI responses, critical for the telephone experience.

Many companies, small and large, struggle to understand why their website isn't performing to its full potential. Performance optimization and technical SEO diagnostics are often complex, unclear, and the recommendations lack precision or are not actionable. The need was therefore to provide a tool capable of simplifying this analysis, identifying blocking points, and offering concrete and measurable improvement paths.

• **Backend API (Node.js, Express.js)**: To manage business logic and interactions with audit and AI services.

• **Front-end (React / Next.js)**: For an intuitive and responsive user interface, allowing audits to be launched and reports to be viewed.

• **Audit Engine (Lighthouse, Core Web Vitals)**: Integration of these tools for collecting raw data on web performance and technical SEO.

• **AI Core (Langchain)**: Development of an Artificial Intelligence engine that analyzes audit data, interprets results, and generates personalized, actionable recommendations for each website.

• **Tracking Feature**: Implementation of a system to compare successive audits to measure continuous improvement in web performance and SEO.

An intelligent web audit platform that transforms a complex technical process into a clear and personalized roadmap.

Companies now have a precise tool to identify optimization levers for their website, understand the impact of AI on their web performance and SEO, and track their progress over time.
