HOW TO READ THIS REPORT

Action plan is what to do next — copy-pasteable changes prioritized by impact. Category visibility is the real GEO test: when a user asks an AI a brand-free question that should surface projectchrono/chrono, does the AI actually recommend you — or your competitors? Objective checks verify the metadata signals AI engines weight first. Self-mention check detects whether AI even knows you exist by name.

Action plan — copy-paste fixes

3 prioritized changes generated by gemini-2.5-flash. Mark items done after you ship the fix.

OVERALL DIRECTION
  • mediumreadme#1
    Strengthen README opening to emphasize comprehensive multiphysics integration

    Why:

    CURRENT
    Distributed under a permissive BSD license, Chrono is an open-source multi-physics package used to model and simulate:
    COPY-PASTE FIX
    Project Chrono is a comprehensive, open-source C++ multi-physics package designed for high-performance simulation of complex systems. It uniquely integrates diverse physical domains, allowing for the modeling and simulation of:
  • mediumreadme#2
    Add a link to a comparison guide in the README

    Why:

    COPY-PASTE FIX
    Add a new section to the README, for example, under 'Features' or 'Getting Started', with a line like: 'For a detailed comparison of Project Chrono with other simulation libraries and its unique capabilities, please visit our [Comparison Guide](http://projectchrono.org/comparison).'
  • lowtopics#3
    Add more specific technical and research-oriented topics

    Why:

    CURRENT
    flexible-body, fluid-solid-interaction, granular-dynamics, modeling, multibody-dynamics, physics-engine, physics-simulation, robotics, simulation, vehicle-dynamics
    COPY-PASTE FIX
