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 NVIDIA/MatX, 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

hightopics#1

Add specific topics to improve categorization for Python-like syntax and array operations

Why:

CURRENT

cuda, gpgpu, gpu, gpu-computing, hpc

COPY-PASTE FIX

cuda, gpgpu, gpu, gpu-computing, hpc, python-like-syntax, matlab-like-syntax, tensor-library, array-programming, numerical-computing

mediumreadme#2
Reposition the README H1 to emphasize Python-like syntax for GPU computing
Why:
CURRENT
```
# MatX - GPU-Accelerated Numerical Computing in Modern C++
```
COPY-PASTE FIX
```
# MatX: Python-like C++ for GPU-Accelerated Numerical Computing
```

lowreadme#3

Add a sentence to the introduction differentiating MatX from general C++ HPC libraries

Why:

CURRENT

MatX is a modern C++ library for numerical computing on NVIDIA GPUs and CPUs. Near-native performance can be achieved while using a simple syntax common in higher-level languages such as Python or MATLAB.

COPY-PASTE FIX

MatX is a modern C++ library for numerical computing on NVIDIA GPUs and CPUs. Near-native performance can be achieved while using a simple syntax common in higher-level languages such as Python or MATLAB. Unlike general C++ HPC frameworks, MatX uniquely combines this expressiveness with the performance of modern C++ for numerical computing.
