TL;DR
Direct answer: A generative engine optimization agency is a retained team that owns a URL list, a frozen prompt set, and an export a client can open without the vendor UI. SEO Health is a checker that agency or client can run. We are not an agency. Diligence is people, evidence, and a refuse state — not a citation-percentage slide.
What you'll learn
- How a generative engine optimization agency differs from a freelancer, a tool, and a services SKU
- A diligence checklist you can take into a vendor call
- Fields that must survive a PDF the client can keep
- Who should run the free check, and why both sides can
- Failure modes that turn a retainer into theater
If you already have a money URL, run a free check before the first agency call. Bring the punch list. Do not let the deck invent the baseline.
What an agency is not
Key Definition: A generative engine optimization agency is a retained team that owns URL lists, prompt sets, and exported punch lists for clients. SEO Health is a checker that agency or client can run. We are not an agency and we do not sell a citation-percentage API.
Quick answer: A generative engine optimization agency is a retained team that owns a URL list, a frozen prompt set, and an export a client can open without the vendor UI. SEO Health is a checker that agency or client can run. We are not an agency. Diligence is people, evidence, and a refuse state — not a citation-percentage slide. Key terms
| Term | Meaning |
|---|---|
| GEO | Making a passage liftable into a generated answer. |
| SEO | Making a URL eligible and clear in classic retrieval. |
| AEO | The same extractability job under an answer-engine label. |
| Extractable block | A short definition, named entity, or dated fact this page can lift. (#547) |
People type generative engine optimization agency when they want a partner, not a seat. This page is the diligence brief. The pair is defined in GEO vs SEO. The hours-versus-software buy is generative engine optimization services. Stay here for the shop that will own the export.
The 4A’s exist because agency work is a profession with duties, not a logo wall. Steal that posture. Ask who is accountable when the export is wrong.
Agency versus freelancer versus tool
A freelancer edits a page. A tool returns flags. A generative engine optimization agency staffs both and keeps a client-ready file. If the shop only forwards a dashboard screenshot, it is a reseller.
SEO Health is the tool. Run the free check yourself or hand the URL to the shop. Same rules. Same report. A generative engine optimization agency owns the interviews, the publish calendar, and the file the client still has after the Slack channel closes.
The software tiers are generative engine optimization tools. Do not let a shop relabel a seat as a retainer.
Why we are not one
We build a checker. We do not interview your legal team. We do not publish your pages. We do not sit in your QBR. A generative engine optimization agency that pretends a checker is a staff is lying about capacity. A checker that pretends to be a staff is lying about the product.
If you only needed the two-job quote, use what is GEO vs SEO. If you needed tactics, use generative engine optimization strategies. If you needed a partner, keep reading.
Independent sites often skip this page and jump to a logo. That is how they buy a logger with a services SKU. A generative engine optimization agency should survive a one-page brief: ten URLs, three query classes, one export format, one kill week. If the shop cannot fill that brief in the first call, you do not have a partner. You have a deck. Write the brief yourself. Bring the free-check notes. Make the shop react to your list.
Diligence checklist
Score the shop on work you can see. We have not retained every firm, and we will not invent a 0–100 “agency GEO score.” A generative engine optimization agency that asks you to trust a proprietary meter before it shows a URL list has already failed the first row.
Bring three artifacts to the call: the punch list from your own check, the money URL set, and the name of the person who can publish. If the shop wants a fourth artifact — a brand questionnaire that restates your about page — postpone it until the URL list is frozen. Diligence is cheaper when the inputs are yours.
People and process
| Check | Pass | Fail |
|---|---|---|
| Named lead | Person a client can email | “The AI team” |
| URL ownership | List with owners | “Priority verticals” |
| Publish path | Who hits publish | “We advise” hidden as delivery |
| Cadence | Weekly file, monthly review | Random Slack dumps |
| Conflict | Discloses other clients in the same niche | Silent |
PRSA ethics materials are the right warning label for disclosure. A generative engine optimization agency that will not say who else it represents in your category is asking you to fund a conflict.
CIPR competence guidance is useful as a staffing test: the person on the call should be the person who writes the export. If the pitch is a founder and the work is a junior with a logger, price it as that.
Evidence and export
Demand mention, citation, and co-mention as separate columns when anyone logs answers. Demand a cannot-score state. Demand a file a writer can assign. A generative engine optimization agency that only emails a doughnut is a slide vendor.
We do not sell a citation-percentage API. If a generative engine optimization agency does, ask for the prompt list, the date, and the log. If those are missing, the percentage is decoration.
Prompt honesty
Ask to see the frozen prompt set. Ask what happens when a model refuses. Ask whether locale is named. A shop that “uses best prompts” and cannot show them will not survive a second quarter.
The W3C Consortium is here as a web-standards reminder, not as a GEO vendor: the export should point at real URLs, real HTML, and real robots rules. A proprietary score that cannot be mapped to a page is not diligence.
The exportable report
The client-keepable file is the product. A generative engine optimization agency that cannot leave that file is renting a UI. Ask to see a redacted export from another engagement. If the sample is a slide with a doughnut and no URL column, stop. If the sample is a table a writer could assign tomorrow, continue.
The file should still make sense when the shop’s login expires. That is the test procurement forgets. A portal is fine as a working copy. It is not the deliverable. A generative engine optimization agency delivers the PDF or Markdown the client stores next to the content brief.
Fields that must survive a PDF
| Field | Why it must survive |
|---|---|
| URL | The work is a page |
| Query class | The layer is not the same on every URL |
| Missing evidence | Definition, entity, crawler, byline |
| Owner | Someone publishes |
| Date of last check | Re-run is the proof |
| Refuse / cannot-score | Honesty |
| Next edit | One flag, not a manifesto |
The three-layer decision that fills the query-class column is SEO vs GEO vs AEO. A shop that marks every URL “GEO” has not read the table.
ASA advertising-standards work is the right brake on claims in that PDF. If the report promises a citation rate the model never logged, it is an ad, not a file. Do not let a client present it as a measurement.
How a client uses the file
The client assigns rows. The client re-runs the same URL after a publish. The client keeps the PDF when the retainer ends. A generative engine optimization agency that locks notes inside a portal is optimizing for renewal, not for the page.
Trust still sits under E-A-T SEO. An export that ignores Experience and only paints a footer is half a report. Mention tracking, when the client needs a tape, sits in the AI visibility tool hub. The agency can use that hub. It should not invent a second meter.
Who runs the checker
Either side can run it. That is the point.
Agency-run check
The shop pastes the URL, gets the punch list, and writes the export. Useful when the client has no time and the shop already owns the calendar. Still require the client to see the raw notes. A generative engine optimization agency that hides the checker output is hiding the work. The client should be able to paste the same URL and see the same flags. If they cannot, the shop is not using a shared checker. It is using a private story.
Run a free check on one URL in the kickoff so both sides see the same flags. If a generative engine optimization agency deck disagrees with the HTML, believe the HTML.
Client-run check
The client runs the same URL before the call and after the publish. Useful when procurement wants an independent baseline. SEO Health is built for that. We are not the agency of record.
IAB UK measurement conversations keep returning to the same idea: a number you cannot reproduce is not a number you should buy. Apply that to a GEO retainer. The client-run check is how you reproduce the file.
If the two runs disagree, the prompt set moved, the page moved, or someone invented a rate. Find which. Do not average them.
Scope and retainers
Write the retainer as URLs and a cadence, not as “AI visibility.” A generative engine optimization agency without a URL column will invoice for meetings.
Put the kill week in the contract. Put the export format in the contract. Put the named lead in the contract. A shop that calls those “process details” is asking you to buy a vibe. Process details are the product. The acronym is the label.
Project versus retainer
A project is a fixed URL list and a re-run date. A retainer is a weekly file plus a monthly review. Buy a project when the leftover list is finite. Buy a retainer when new money URLs appear every month and someone will read the file.
Do not buy a year because the shop said “GEO takes a year.” Eligibility can be a week. A definition can be an afternoon. Interviews can be a quarter. Price the interviews, not the acronym. A generative engine optimization agency that cannot split those three clocks will bill the slowest one for all of them.
What a weekly tape looks like
Week one: ten URLs, one export, no new locale. Week two: three publishes, one re-run. Week three: leftover interviews. Week four: keep or kill. A generative engine optimization agency that skips the kill decision is a subscription.
Run the free check on the three published URLs at week four. If the notes did not move, the generative engine optimization agency retainer did not deliver. Do not renew a chart.
Failure modes
- Treating a checker as an agency. We are not one.
- Treating a screenshot as an export.
- Printing a citation percentage the model never logged.
- Hiding the prompt set.
- Marking every URL “GEO.” Query class still matters.
- A retainer with no kill week.
If a shop already failed one of those, re-run the free check on your side and bring the punch list to the next call. Diligence is a file. It is not a vibe.
Frequently Asked Questions
Is SEO Health an agency?
Bottom line: No. SEO Health is a checker. A generative engine optimization agency is a retained team. Either side can run the check. We do not staff your backlog.
What should I demand in the export?
Bottom line: generative engine optimization agency: URL, query class, missing evidence, owner, date, refuse state, next edit. If those fields die in a portal, you rented a UI.
Who should run the checker?
Bottom line: Either the generative engine optimization agency or the client. Run it once together in kickoff. Run it again after publish. Disagreement is a finding, not a rounding error.
How do I compare two retainers?
Bottom line: Same three URLs, same week, same export fields. The shop that cannot show a cannot-score state loses. Price follows the named lead, not the deck. A cheaper generative engine optimization agency that cannot name the publisher is not cheaper. It is unfinished.
What is the first diligence call?
Bottom line: Pick one money URL. Run a free check. Ask the shop to work from that list. If the answer is a new slide, you do not have a partner.
Conclusion
A generative engine optimization agency owns the URL list, the prompt set, and a file the client can keep. SEO Health is the checker that agency or client can run. We are not an agency. Run the free check before you sign, and again after the first publish. Use the hub when you still need the pair explained.
