1. HTML-to-Token Efficiency & LLM Context Window Cost

An unauthenticated HTTPS GET request to https://www.microsoft.com/en-in returns an initial HTML payload of 174.0 KB, corresponding to approximately 44,551 UTF-8 tokens when ingested raw by an AI coding agent, retrieval pipeline, or headless browser. After stripping inline <script>, <style>, <svg>, and DOM markup tags, the human-readable text footprint measures 859 tokens (3.4 KB)—yielding an HTML Signal-to-Noise Ratio of 1.9%. Because microsoft.com does not currently serve a machine-readable /llms.txt manifest at its root path, autonomous agents must either parse the full 44,551-token HTML payload ($55.6888 per 1,000 frontier reads) or run a DOM-stripping pass before grounding.

2. AI Crawler Governance & /robots.txt Posture

Based on live inspection of https://microsoft.com/robots.txt, microsoft.com maintains a Open to Search & Training posture. Specifically, AI search citation crawlers (OAI-SearchBot: Allowed, PerplexityBot: Allowed) and foundation model training crawlers (GPTBot: Allowed, ClaudeBot: Allowed, CCBot: Allowed) are governed explicitly by the host’s root robots policy.

3. Edge Delivery, TLS Handshake & Security Header Assessment

Traffic for microsoft.com resolves to 150.171.109.132 via Direct Origin running Custom SSR / Static, achieving a measured Time to First Byte (TTFB) of 120 ms (DNS lookup: 4 ms, TCP connect: 20 ms, TLS handshake: 0 ms). The port 443 TLS certificate is issued by Microsoft Corporation with 77 days remaining before expiration (valid through 2027-01-30). Outbound email authentication via SPF is present and DMARC (_dmarc.microsoft.com) is enforced.
