The answer layer

Answer engine optimization

Answer engine optimization (AEO) is the practice of making your content the source that AI assistants cite when they answer a question. Where SEO earns a ranking, AEO aims to earn brand mentions and source citations in AI answers.

What is answer engine optimization?

AI answers can mention a brand, cite its website, do both, or neither. AEO is the work of making your content accessible, useful and credible for those answers. It includes how you structure the page, support its claims and make the source easy to identify.

It matters because the click is no longer the unit of victory. A buyer can get a recommendation, a comparison and a shortlist without ever seeing a results page. If the answer names you, you were in the meeting. If it does not, you were not.

How is AEO different from SEO?

SEO and AEO are not competing disciplines. Answer engines still use search indexes to find source material, so a page has to be discoverable before it can be cited. SEO gets the page into consideration. AEO makes the answer easy to quote and attribute.

How do AI engines choose what to cite?

Each engine works differently, but the pattern across them is consistent: the engine searches, reads a shortlist of pages, and quotes the passages that answer the question most directly. Three properties keep showing up in cited pages:

How do you get cited by AI search?

The playbook I run, in order:

  1. One canonical URL per definition you want to own. If your category explanation is smeared across fourteen partial pages, machines resolve fourteen partial answers. Give each definition one home and link everything else to it.
  2. Question-first headings, answer-first paragraphs. Head the section with the question buyers actually ask, then answer it in the first sentence beneath.
  3. Make facts extractable. Tables for comparisons, numbered lists for processes, a stated definition for every term you want attached to your name.
  4. Structured data on the same pages. Article, FAQPage, Dataset and Person markup that mirrors the visible text, so machines get the same claims twice.
  5. Publish an llms.txt. A plain markdown index of your canonical pages at your site root, alongside your sitemap and structured data.
  6. Publish useful evidence. Original research or a maintained dataset gives readers a reason to cite your work. One example is the failover economy dataset.

How do you measure whether it works?

Keep three questions separate: did the answer mention the brand, did it cite the website, and did the work help a buyer move toward a purchase?

For Google, Semrush can show historical organic rankings and whether a domain appeared in an AI Overview. For other assistants, my open-source citation meter records cited sources returned through their APIs. API results are a separate observation from what a person sees in a consumer chat product. A domain citation count is also different from a count of brand mentions or recommendations.

Track public visibility alongside buyer feedback, qualified conversations and pipeline. When buyers learn without clicking, referral traffic captures only part of the picture. Avoid turning citation share into a revenue attribution claim.

Leading AEO at OnPay

During my January-August 2026 tenure as VP of Growth Marketing, I set the AEO vision and execution plan, aligned stakeholders, coached the content and technical teams, and supervised delivery.

The program supported commercial outcomes. I do not assign AEO a standalone revenue figure. Buyers can learn from an AI answer without clicking, so the route from discovery to purchase is not fully visible in referral analytics.

What the public search record shows

Semrush’s US desktop data records OnPay at organic #1 for “farm payroll software” in February 2026. OnPay is absent from the AI Overview source rows returned in that snapshot. In April 2026, it remains organic #1 and appears among the AI Overview sources. Both observations recur in the June and August snapshots.

Those observations fall within my tenure. The December 2025 and January 2026 reports return no data for that exact query, so they cannot establish when the organic ranking began or what caused it. Several nonprofit rankings and AI citations already existed before I joined: the December 2025 data shows organic #1 for “payroll for nonprofits” and “nonprofit payroll services,” plus an AI Overview citation for “payroll for nonprofits.”

AI Overview source rows can all carry position 1 because the answer block occupies that search position. That does not establish the first source cited, a first-place recommendation, or leadership across other AI engines.

What I bring to the next team

Leadership means choosing the right buyer questions, aligning content and technical work, coaching the people doing it and holding the plan to a commercial purpose. I also publish my own measurement tools through Skill Trade, so you can inspect how I work.

Questions people ask

Is AEO the same as GEO?

Same discipline, different labels. Answer engine optimization, generative engine optimization (GEO) and AI search optimization all describe optimizing to be the source generative answers cite. The names will consolidate; the practice is already one thing.

Does llms.txt matter?

I maintain llms.txt as a concise index of the site's canonical pages, alongside clear HTML, structured data and crawler access. It is inexpensive to keep accurate. It does not establish that a particular engine will retrieve, cite or recommend the site.

Do you need to rank #1 to be cited by AI answers?

No. Organic rank and AI citations are separate observations. Track each separately.
