Live · Generative Engine Optimization · Edge SFE

Get cited by AI search—not buried under it.

SFE-Edge sits in front of your site on Cloudflare Workers. When AI crawlers visit, it rewrites structure (headings, chunks, lists, bold anchors, schema)—not your meaning—so models can extract and cite you.

Humans always see your original page. Only AI bots get SFE mutations. Multi-tenant proxy is live—provision in minutes.

How it works

Structural Feature Engineering (GEO-SFE) at the CDN—built for ChatGPT, Perplexity, Claude, and Google AI Overviews.

Detect AI crawlers GPTBot, ClaudeBot, PerplexityBot, and friends—humans passthrough.
Compile structure at the edge Macro hierarchy, meso chunking, micro emphasis—size-gated for free-tier CPU.
Cache smart Edge Cache API first; Workers KV sparingly so free write limits survive crawls.
Serve machine maps Free /llms.txt; bulk /llms-full.txt ready for agent-scale indexing.

Built for citation readiness

Engine profiles

Tuned structural weights for ChatGPT (tables & listicles), Perplexity (FAQ & stats), Claude (E-E-A-T), and Google (schema-first).

High-influence zone

TOC, answer-first leads, and claim anchors front-loaded into the first ~30% of body content—where models extract hardest.

Free-tier honest

50 KB buffer cap, streaming degrade, dual-layer cache, and request coalescing so Cloudflare free limits don’t blow up.

Zero human risk

Structure-only mutations for bots. Your visitors never see layout shifts or experimental rewrites.
