SEOLinkMap breaks the SEO industry by proving most advice is wrong. Every other tool gives the same tips for all keywords. We show why this fails using real math and stats. The problem: SEO platforms ignore context. They say "write long content" or "add more links" without asking what users want from different searches. Our data proves this approach backfires. We studied thousands of top pages across various keywords using 40+ ranking factors. The shocking result: what helps rankings for one search term hurts another. We found opposite rules for different contexts, backed by correlation data, p-values, and confidence intervals. Our engine uses academic-level stats for commercial SEO. We run proper tests, report limits when data is thin, and apply fixes for multiple comparisons. No marketing fluff - just clear numbers. The platform works with Google Analytics, Search Console, and AI agents via Model Context Protocol. Interactive network maps powered by Cytoscape.js show your site structure in ways spreadsheets can't. Switch between metrics and watch the whole network update instantly. Pricing is flexible: free tier, monthly plans, or pay-per-use credits for deep analysis. Our competitor research doesn't just show what works - it proves why with statistical backing. Key insight: Each search context creates unique user expectations. We analyze what characteristics currently successful pages share within specific search results, providing SERP-specific optimization intelligence instead of generic advice. This isn't another SEO tool. It's a complete rethink of how optimization should work when every search context is unique.
