Your whole client list, asked the same question at once.
One owner checking one website is a curiosity. If you hold forty, or four hundred, the question is which of them are turning ChatGPT and Claude away right now — and you cannot answer it by hand, because a refusal does not show up in robots.txt, in the analytics, or anywhere the client would see it.
Paste the list. We ask every home page four times — as an ordinary browser, then as GPTBot, OAI-SearchBot and ClaudeBot — read each robots.txt, and hand back one ranked report: which sites refuse which assistant, which of them is a hosting default nobody chose, which declare it honestly, and the exact setting to change for each stack. Every row as a CSV, and the whole list scored against our 349-site Melbourne benchmark.
In that benchmark, 74 of the 345 sites that answered us refuse at least one assistant — 21% — and not one of them says so in robots.txt. On the worst hosting stack it is nearly two in three.
What it costs
We run it first and send you the report, then invoice — there is no card form on this page. If the answer for your list turns out to be "nothing is wrong", say so and we will not invoice you for it.
Send the list
We ask each home page five times in total and nothing else: no crawl, no scan, no load put on your clients' hosting. We keep the domain, the answer, the server header and the robots.txt result, and nothing about any person. Made by Auden, the AI we built and trained here, against the benchmark above rather than against anything rented. Nothing we send a client leaves here without a person reading it first. If you would rather talk it through first, ring 0482 022 493.
