Quick Start: Set Up Your Agent OS To Vet Agencies
- Create a project folder called
aeo-vettingand drop in each agency's proposal or service page URL. - Add a file of reference links: Google's generative AI optimisation guide, Google's hiring an SEO page, OpenAI's crawler overview and Bing's Webmaster Guidelines.
- Give the agent read-only web access and tell it never to send emails or fill forms.
- Run the three prompts below in order and save each output as a dated file.
Prompt 1: Check An Agency's Offer Against The Platforms' Own Rules
Read the AEO service page or proposal at [URL].
Then read these official pages:
- developers.google.com/search/docs/fundamentals/ai-optimization-guide
- developers.google.com/search/docs/fundamentals/do-i-need-seo
- developers.openai.com/api/docs/bots
Make a table with three columns: claim the agency makes,
what the official pages say, and verdict (matches / contradicts / not covered).
Flag any guarantee of rankings or AI citations,
any reliance on llms.txt or "chunking" for Google,
and any link tactic Google's spam policies call link spam.
Quote the exact sentence for every flag. Do not contact the agency.Google's guide lists chunking, llms.txt files and fake mentions among the tactics Google Search simply does not need, so expect the table to catch those first.
Prompt 2: Test Your Own Robots.txt For AI Search Crawlers
Fetch https://[my-domain]/robots.txt.
For each user agent below, tell me whether it is allowed to crawl
the homepage and my main service pages:
Googlebot, OAI-SearchBot, GPTBot, PerplexityBot, Claude-SearchBot, ClaudeBot.
Explain which ones control AI search visibility and which control training,
citing the official docs for each. Then draft (do not apply) a corrected
robots.txt that allows the search bots. Flag any "User-agent: *" + "Disallow: /".This matters because OpenAI's ChatGPT search article makes OAI-SearchBot access the condition for inclusion, Perplexity's docs say the same of PerplexityBot, and Anthropic's help page warns that blocking Claude-SearchBot may cut your visibility in Claude search.
Any agency worth hiring should spot the same issues in week one; if your agent finds them and the proposal does not mention them, mark it down.

Prompt 3: Build A Question Baseline Before Any Agency Starts
Here are my last 50 customer emails and call notes: [paste or attach].
Group them into the 20 questions customers ask most before buying.
For each question, write the exact wording a customer would type into
ChatGPT, Perplexity or Google AI Mode.
Output a sheet with columns: question, page on my site that answers it
(or "none"), and notes. Draft only: do not publish or change anything.Run those 20 questions yourself in each engine and log who gets cited; that log becomes the baseline you hold any agency to.
For measurement after launch, Google's Search Console now has generative AI performance reports and Bing shows Copilot citations in its AI Performance report.
How To Read The Agent's Outputs
Treat the three files as a scorecard, not a verdict.
- A proposal with several "contradicts" rows in Prompt 1 should go to the bottom of the pile.
- A blocked search crawler in Prompt 2 is your first fix, whoever you hire, because nothing else matters until it is solved.
- A long list of "none" answers in Prompt 3 tells you how much new content the job really needs, which helps you judge whether a proposal is realistic.
Keep a human check on every row; agents misread pages, so open the quoted source before you act on a flag.
A Small-Business Example: The Dog Groomer
- The owner runs Prompt 3 on six months of booking messages and gets questions like "how often should a cockapoo be groomed".
- Prompt 2 shows a stray
Disallow: /left by the web designer, blocking every crawler. - She asks two agencies for proposals and runs Prompt 1 on both.
- One promises a guaranteed ChatGPT mention, which the agent flags against Google's hiring page; the other starts with crawler access and a question baseline.
- She books the second, keeping her baseline sheet to check progress after 90 days.
When To Hand It To A Pro
Your Agent OS is brilliant at reading, checking and drafting.
It will not interview your staff for first-hand detail, earn a mention from a trade journal or decide which pages to rebuild first.
That judgement is where a team pays for itself, so once the three prompts have done their job, Book a free SEO strategy session with Julian's people.
You can also read the companion guide on how to rank in ChatGPT in your Agent OS.
What Nobody Can Promise You
Google's hiring page states that no one can guarantee a #1 ranking on Google.
OpenAI says ChatGPT search placement is not guaranteed, and Bing says GEO does not guarantee citations in AI experiences.
Use that as your filter: the right provider promises clear work and clear reporting, never a spot in an AI answer.

FAQ
Can my Agent OS replace an AEO agency?
It can handle the reading, crawler checks and question research. It cannot earn genuine mentions or supply first-hand expertise, which is where a team earns its keep.
Which crawlers should Prompt 2 check?
Googlebot, OAI-SearchBot, GPTBot, PerplexityBot, Claude-SearchBot and ClaudeBot. The search bots affect AI answer visibility; GPTBot and ClaudeBot relate to training.
Should the agent ever contact agencies for me?
No. Keep it read-only and draft-only, and send any messages yourself after reviewing them.
What should I do with the question baseline?
Rerun the same questions every month in ChatGPT, Perplexity and Google AI Mode and compare who gets cited, alongside Search Console and Bing data.
