Generative Engine Optimization Agency: The Brief

01 What the brief should specify

A useful brief names the desired result and its evidence. Define the source connections, page improvements and reporting the engagement will deliver.

1. Name the templates in scope. Not "the site". List the page kinds: product, category, location, article, service, FAQ.
2. Require a baseline first. A readability score per template against a published spec, taken before any change and handed to you as numbers.
3. Specify the serving outcome. Accept: text/markdown returns the page’s facts, and the response is a stated fraction of the HTML size.
4. Specify fact position. The first substantive fact appears within the first few lines rather than tens of thousands of characters in.
5. Choose the operating model. Agree on hosting, source access, exports, code ownership and ongoing maintenance.
6. Combine server-side request reporting with browser analytics. The gateway observes requests it handles; the Rebilder Tag records AI-referred visits and supported browser activity.

02 The clause that protects you

Agree how the integration will operate after the engagement ends. For hosted services, cover export, migration and continued service; for self-hosted middleware, cover code ownership and maintenance.

03 Clarify measurement and responsibility

• Define the result. Separate delivered work from observed outcomes, and agree how performance will be measured and attributed.
• Keep sampled answer positions separate from search rankings. Document which prompts, models and dates were sampled, and report your own agent requests and referrals alongside them.
• Competitor comparisons. Use sourced, dated observations with a clear sampling method. Named editorial comparisons and verified index listings use distinct publication policies.

Frequently asked questions

What does a generative engine optimization agency do?
A technical half covering how your pages are served to AI agents, and an editorial half covering content that answers real questions. Both technical and editorial work need maintenance as sources, products and customer questions change.

What should I put in a GEO brief?
Specify the source and page improvements, a starting baseline, the reporting method and ownership. Choose self-hosted or managed operation according to the business’s needs.

How do I check the work was done?
Request a page with Accept: text/markdown and read what comes back, measure it against the raw HTML size, re-run the readability scan against the baseline, and confirm Googlebot still receives canonical HTML. All four are free.

How should a GEO agency measure results?
Ask the agency to define the work, evidence and measurement window. Source selection remains with each assistant, so the agreement should distinguish delivery from observed outcomes.
