The setup

Last Tuesday evening I opened the Supabase dashboard and ran a few queries on my product's traffic.

ChatGPT referrers over the past month: 3 visitors

Bing site:tamsiv.com operator: 0 results

Common Crawl captures for the domain: 0

Google referrers per week: ~10 (stable)

So I had one fragile channel (ChatGPT was finding the site through OAI-SearchBot crawling directly + dev.to backlinks), and everything else was empty.

But ChatGPT isn't all the LLMs. Each major assistant has its own search backend, and optimizing for one doesn't transfer to the others.

The map I hadn't drawn

LLM Search backend TAMSIV status

ChatGPT search, Copilot Bing invisible

Claude (Anthropic) Brave Search + own crawler P1 on long-tail queries

Gemini, AI Overview Google indexed, ~10 referrers/week

Perplexity Bing + DuckDuckGo + own crawler unknown

Grok X/Twitter + own absent (no X presence)

You.com, Kagi mostly Bing unknown

DeepSeek, Mistral, Llama (open-source) Common Crawl (training corpus) zero captures

Out…
