How AEO differs from SEO for B2B businesses
SEO optimises your website to rank in search engine results pages. AEO, answer engine optimisation, optimises your content to be cited by AI systems like ChatGPT, Claude, Gemini and Google's AI Overviews when they answer questions directly. SEO wins you clicks from people who search. AEO wins you citations from AI systems that answer on behalf of people who no longer click at all.
This guide explains what each discipline does, the four differences that matter commercially, how to assess where you stand and what to improve first.
What is SEO and what does it do for B2B?
SEO is the practice of making your website rank higher in Google and other search engines. It works through a combination of keyword-targeted content, technical site health, and links from other credible websites. When someone searches "B2B consultancy London" or "HR software for small businesses", SEO determines whether your site appears on page one or page five.
For B2B businesses, SEO has been the primary driver of organic visibility for the past two decades. It still works. High-intent search traffic, where someone is actively looking for what you offer, converts well. If you have invested in SEO, that investment is not wasted. But it was built for a world where people clicked through to websites, and that world is changing.
What is AEO and why does it matter now?
When someone asks ChatGPT, Claude, Gemini or Google's AI Overviews a business question, those systems do not return a list of links. They return an answer, drawn from content they have assessed as credible, structured and relevant. The user may never visit a website at all.
AEO is the practice of making your content the source those systems cite. It requires a different approach to traditional SEO: direct answers to specific questions, clearly structured pages, and content that reads as authoritative rather than keyword-dense.
The core shift: SEO asks "how do I rank?" AEO asks "how do I get cited?"
For B2B professional services firms, this matters because your buyers already use AI tools to research suppliers, compare options and shortlist providers. If your content is not structured to be cited, you are invisible in that part of the buying process. The five most common reasons B2B businesses are missing from AI answers cover the diagnosis in more detail.
The four key differences between AEO and SEO
The disciplines overlap, but they diverge on four things that change how you plan, write and measure.
| Dimension | SEO | AEO |
|---|---|---|
| Intent signal | Targets keywords | Targets questions |
| Success metric | Click-through traffic and rankings | Citations and brand mentions in AI responses |
| Content format | Rewards depth, dwell time and comprehensive coverage | Rewards directness, quotability and clear structure |
| Buyer stage | Captures buyers who are actively searching | Influences buyers before they have formed a search query |
Difference 01
Intent signal
SEO is built around keywords: terms people type into a search bar. AEO is built around questions: the full-sentence queries people put to AI systems. "B2B marketing agency" is an SEO keyword. "Which B2B marketing agencies are worth speaking to?" is an AEO prompt.
Three practical actions
- List the ten questions buyers ask before they shortlist a supplier in your category.
- Give the most commercially important questions a dedicated page rather than a paragraph.
- Write section headings as the question, then answer it immediately underneath.
Difference 02
Success metric
SEO success is measured in rankings and clicks. AEO success is measured in citations: how often your content appears as a source in AI-generated answers. These require different tools to track.
Three practical actions
- Record a fixed set of unbranded prompts and check them on a regular cycle.
- Track branded and unbranded mentions separately so progress is visible.
- Report citations alongside rankings rather than replacing one with the other.
Difference 03
Content format
SEO rewards long, comprehensive content that keeps readers on the page. AEO rewards content that answers a specific question directly, in the first sentence, in plain language. Quotable, structured, unambiguous.
Three practical actions
- Lead every section with the answer, then add the supporting reasoning.
- Use clear headings, short paragraphs and lists that can be lifted cleanly.
- Remove hedging language that makes a passage impossible to quote.
Difference 04
Buyer stage
SEO captures buyers at the moment they search. AEO influences buyers earlier, when they are researching a category or problem and asking an AI to orient them. That is often before they have a shortlist, or even a clear brief.
Three practical actions
- Publish category and comparison content, not only service pages.
- Make your audience, sector focus and location explicit on every key page.
- Link early-stage content to a clear next step so the trail leads somewhere.
The three conditions behind AI visibility
Whether you call it SEO or AEO, the same three conditions decide whether your business gets named. They are the basis of the Glint Visibility Architecture.
Layer 01
Retrievability
Can buyers and AI systems find and read what you publish?
Layer 02
Extractability
Can they understand and use the answers you provide?
Layer 03
Authority
Is there enough credible evidence to trust your business?
Strong visibility needs all three conditions together, not isolated technical or content work. Sustaining them is ongoing work, which is what our retained partnerships are built around.
Do B2B businesses need both SEO and AEO?
Yes. They serve different moments in the buying process, and ignoring either creates a gap.
SEO still drives traffic for high-intent queries. When a buyer is ready to evaluate suppliers and types a specific search term into Google, you want to be there. That has not changed.
AEO covers a different moment: when a buyer is earlier in their thinking and turns to an AI tool to understand a category, compare approaches or get a quick orientation. That moment is now standard at the top of the B2B funnel.
The risk of ignoring AEO is not that SEO stops working. It is that buyers are vetting you through AI before they ever reach your website. If you are not cited in those responses, you do not exist in that part of the research process. By the time they run a Google search, the shortlist may already be formed.
Assess your current AEO readiness
Answer yes only where the evidence is already published and easy for someone outside your business to find.
- Do your most important pages answer a specific buyer question in the first two sentences?
- Can every commercial claim be read as text, rather than sitting inside an image or PDF?
- Are your services, audience and location described consistently across external profiles?
- Do you publish client outcomes with a clear result, not just a description of the work?
- Is your founder expertise visible through commentary, speaking or contributed writing?
- Does your site use clear headings, internal links and structured information?
- Are you tracking unbranded AI mentions separately from branded search traffic?
- Is there an obvious route from any piece of content to an audit or a conversation?
If several answers are no, the gap is rarely more activity. It is clearer answers, better structure and stronger proof.
What to improve first
Sequence matters more than effort. This is the order we generally work in.
- 1Clarify what your business should be known for, and for whom.
- 2Rewrite core service pages so they answer commercial buyer questions directly.
- 3Publish client outcomes and founder expertise where they can be found and verified.
- 4Remove technical barriers that stop important content being retrieved or parsed.
- 5Build a small set of answer pages around the questions buyers research first.
- 6Earn independent corroboration through reviews, directories and expert commentary.
- 7Measure unbranded AI citations separately from rankings and branded traffic.
The correct priority depends on your starting point. A business with strong content but a hard to crawl site begins somewhere different to one with a clean site and no published proof.
AEO is a clarity problem before it is a technical problem
Technical work matters, and it should be done properly. But it cannot compensate for vague positioning, unclear commercial content or limited proof. A perfectly optimised page that does not say anything specific about who you help, and what changes as a result, gives an AI system nothing worth citing.
