gr-backlinks — Systematic Backlink Building

Why this skill exists

Phase 2 missing piece: We do title/content/schema/cluster optimization but have zero systematic backlink work. Article research (2026-05): backlinks are the #1 GEO signal — LLMs decide citations partly by brand authority, which is downstream of backlink graph.

For Iris's site (gingiris.github.io, subpath under GitHub Pages), the domain authority ceiling is fundamentally capped without external backlinks. No on-page work can beat Wikipedia / Hootsuite / Wired for head terms — only backlink quality + count can.
