{"@context":"https://schema.org","@type":"Dataset","name":"Crawled — which machines read a small website","description":"First-party record of AI and search crawler fetches against projectnothing.ai, at page granularity, with time from publication to first machine read, and a fixed holdout of pages published without a machine-readable brief.","url":"https://www.projectnothing.ai/experiments/crawled","license":"https://creativecommons.org/licenses/by/4.0/","creator":{"@type":"Organization","name":"Project Nothing","url":"https://www.projectnothing.ai"},"isPartOf":{"@type":"WebSite","name":"Project Nothing","url":"https://www.projectnothing.ai"},"experiment":"https://www.projectnothing.ai/e/crawled","method":{"collection":"Every request to a tracked public path passes through edge middleware, which matches the user-agent against a fixed table and records one row. Requests are counted before any cache, which is the only place these fetches are visible at all.","identification":"A user-agent is a claim, not a proof. Nothing here is verified by reverse DNS or published IP range, so an agent that lies is recorded as whatever it said.","excluded":"Agents not in the table are not counted, and neither are paths outside the tracked set. An unknown-bot bucket would be mostly scrapers and uptime checks, and putting that beside GPTBot would flatter the result.","arms":"Half of the experiment story pages publish a machine-readable brief and are listed in /llms.txt; half deliberately do not. Assignment is the parity of the experiment number — even numbers publish a brief, odd numbers do not — fixed before measurement began. Experiment numbers run in time order, so the arms are balanced and stratified by age at once. The two arms are not compared until each has at least 3 pages read by the answer layer.","absence":"A path no machine has asked for reports null, never zero. \"Nobody came\" and \"we have not watched long enough\" are different facts.","cannotSee":"Whether any of this reaches an answer. Nothing here observes a citation, a recommendation, or a purchase made by an agent — those require a channel that does not exist, and no number on this page should be read as measuring them."},"taxonomy":[{"id":"chatgpt-user","label":"ChatGPT-User","operator":"OpenAI","purpose":"answer","purposeLabel":"Fetching live to answer
