For the Poincaré half-space model in dimension 2, the metric evaluates on the coordinate tangent vectors \(\frac{\partial}{\partial x}, \frac{\partial}{\partial y} \in T_pM\) as \[g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\;\frac{\partial}{\partial x^j}\bigg|_p\right) = \frac{1}{y^2}\,\delta_{ij},\] i.e. the coordinate tangent vectors are orthogonal and each has length \(\frac{1}{y}\) — shrinking to zero as \(p\) approaches the boundary \(y\to 0\), which is what makes the space “infinitely large” near the boundary.
The benefit extends beyond AI optimization. Structured content is easier for human readers to scan and comprehend too. People increasingly skim content rather than reading every word, and clear structure helps them extract key information quickly. When you optimize for both AI processing and human scanning through better structure, you improve the experience for all visitors while increasing AI citation rates.
，这一点在91视频中也有详细论述
