Institutional Methodology & Automated Mathematical Test Fixtures

Q: Who authors and verifies the mathematical models on IndexChecker.online?

All calculators, robots.txt parsers, and AEO pricing matrices on IndexChecker.online are engineered and audited by the Search Indexation & RAG Telemetry Standards Desk against primary technical standards (IETF RFC 9309, W3C Sitemaps 0.90, US Patent 9,916,366 B1, and ACM SIGKDD 2024 GEO benchmarks).

By Search Indexation & RAG Telemetry Standards Desk Verified by W3C & IETF Protocol Verification Panel AI-Assisted & C2PA Editorial Policy Updated October 20, 2026

Search Indexation & RAG Telemetry Standards Desk benchmarks client-side indexation diagnostics, RFC 9309 crawler exclusion parsers, and multi-engine LLM citation economics. Every interactive component on IndexChecker.online is governed by deterministic mathematical test fixtures (`TC-00` through `TC-05`) with zero server-side data exfiltration.

TEST FIXTURE TC-01

Multi-Engine Run & Cost Solver

100 prompts × 30 days × 3 engines = 9,000 checks (or 300 × 30 × 1 = 9,000). Direct API floor at $0.003/run = $27.00/mo; Otterly.ai Starter at $29/mo and 10k Flat at $99.00/mo vs ZipTie metered at $180.00/mo.

TEST FIXTURE TC-02 & TC-04

SOV Deficit & API ROI Arbitrage

45 / 250 = 18.0% Brand SOV vs 80 / 250 = 32.0% Competitor SOV (-14.0% deficit). At 10,000 runs, raw API ($30.00/mo) saves $119.00/mo (79.9%) vs $149.00/mo SaaS.

TEST FIXTURE TC-05
