Graphite
Updated 2026-10-02Growth-marketing agency turned AEO operator, San Francisco. Best known for the Five Percent research series and founder Ethan Smith's AEO playbook. Recent work: a June 2026 model-collapse simulation, the 45-billion-session AI search study, and an August 2026 finding that forced search inflates prompt-tracking numbers.
Three scores, refreshed weekly from live market signals rather than a once-a-year analyst report. Presence is how established a vendor is in the market right now. Velocity is how fast they are shipping, raising, and winning customers. Agent Readiness is how easily your own agents can build on them through an API, MCP server, SDK, or CLI. Scores are relative across the vendors we track; the raw inputs ship in the downloadable dataset.
The Solution & Approach
Graphite started as a boutique growth-marketing agency and turned its SEO practice into a product. In May 2024 it launched a self-service Topical SEO platform: a Topic Graph database, topical-authority scoring, real-time monitoring, and an Internal Links API. Beta client Fourthwall reported 2,301% traffic growth and a 936% SEO revenue increase in nine months. The agency model still runs underneath, which is why this sits on the Hire side of the AEO/GEO market rather than the Buy side.
The research engine is doing as much work as the product. The Five Percent series publishes original studies built on Similarweb panel data and large keyword samples, with named authors carrying PhDs. The findings tend to cut against consensus: organic search traffic fell only 2.5% year over year in 2025, not the 25-60% drops in industry commentary. AI assistants generate 45 billion monthly sessions, 56% of search engine volume, with 83% of that inside mobile apps everyone else was missing. Rand Fishkin publicly challenged the methodology on the second one and Ethan Smith answered back.
Graphite's category POV is that AEO measurement is not yet trustworthy. Its August 2026 piece named a specific defect: some prompt-tracking tools force ChatGPT to run a web search when collecting responses, which no user does. On prompts that don't naturally trigger search, visibility differs by 20 points on average. The recommendation is to let the model decide and report grounding rate per prompt. Worth noting Graphite sells AEO services while its rivals sell the tracking tools.
Best for
Teams that want AEO and topical-SEO work done for them by operators with a public research record, rather than a dashboard they have to staff.

Agent Experience
How you build on this platform (or wire it into your own agents):
| Surface | Available | Docs |
|---|---|---|
| API | No | — |
| MCP | No | — |
| SDK | No | — |
| CLI | No | — |
| llms.txt | No | — |
The Internal Links API is the one documented programmatic surface, so this is a service engagement first and a platform to build on second.
