How to Get Your B2B SaaS Cited in ChatGPT Search, Perplexity & Claude (2026 Playbook)
Updated 2026-10-31 · Grounded in live HTTP telemetry across 1073 B2B SaaS domains · By Liam Vance
When a CTO or VP of Engineering asks ChatGPT Search, Claude, or Perplexity “Best SOC2 [Category] API under $1,000/mo” or “YourSaaS vs Incumbent”, the answer engine does not read client-rendered React bundles. It dispatches parallel sub-queries looking for plain-text pricing, compliance, and entity schemas. Across 1073 funded B2B SaaS domains, the average homepage ships 267.0 KB of HTML and 30.3 script tags, while 81.9% return 404 on /pricing.md and 99.8% lack /ai/summary.json.
5 Deterministic Surfaces That Win Buyer Citations
| Step | Endpoint | Why Answer Engines Cite It |
|---|---|---|
| 1 | /robots.txt (27 Bots) | Explicitly allows OAI-SearchBot, Claude-SearchBot, and PerplexityBot even if training crawlers stay restricted. |
| 2 | /llms.txt & /llms-full.txt | Gives retrieval rankers a clean UTF-8 Markdown map of product architecture, docs, and comparison pages without SPA soft-404s. |
| 3 | /pricing.md & /answers.md | Eliminates tier hallucinations by publishing exact USD plans, overage rules, and 50-word factual answers. |
| 4 | /ai/summary.json & /.well-known/mcp.json | Exposes typed JSON entity facts (SOC 2, SLA, category, alternatives) plus Model Context Protocol & OpenAPI 3.1 tool descriptors. |
| 5 | Homepage @graph JSON-LD | Links Organization + SoftwareApplication + FAQPage in <head> via HTMLRewriter in <2ms. |
