AEO vs SEO: Where Should a B2B Tech Company Invest in 2026?
TL;DR
SEO and AEO are not the same game. SEO wins you Google blue links. AEO wins you AI citations. For B2B companies where buyers are using ChatGPT to build shortlists before your sales team even knows a deal exists, AEO is now the higher-ROI investment. But you need both. This post covers what each optimises for, how the signals differ, where they overlap, and how to allocate your budget between them.
Here is the uncomfortable reality of B2B marketing in 2026: your buyers have already ranked you before they contact you.
According to Forrester's 2026 Buyers' Journey Survey of nearly 18,000 global business buyers, 94% of B2B buyers used AI during their most recent purchase process, and AI tools outranked vendor websites, sales reps, and product experts as the most meaningful source of purchase information. A G2 survey of 1,076 B2B decision-makers in March 2026 found that 33% of buyers purchased from a vendor they had never previously heard of, discovered entirely through an AI-generated answer.
One in three. Discovered through AI. Not Google. Not a referral. Not a cold email.
If your company is not appearing in those AI-generated answers, you are not losing at the bottom of a search results page. You are losing before the conversation starts.
The question, then, is not whether to care about AI visibility. It is how to allocate your marketing investment between the engine you have been optimising for and the engine your buyers are now using.
What SEO and AEO Actually Optimise For
Most people treat these as variations of the same thing. They are not.
SEO (Search Engine Optimisation) is the practice of making your content rank in Google's blue-link results. The signals that drive rankings are well understood: backlinks from authoritative domains, keyword relevance, page speed, mobile-friendliness, E-E-A-T signals, and internal link architecture. When someone types a query into Google, the algorithm ranks pages and serves a list. Your job is to be near the top of that list.
AEO (Answer Engine Optimisation) is the practice of making your brand get cited inside AI-generated answers. The signals are different: structured data and schema markup, third-party citation footprint (Reddit, directories, publications), content structured to deliver a direct answer in the first 100 words, entity consistency across the web, and FAQ schema that lets LLMs pull individual Q&A pairs as standalone citations.
When someone asks ChatGPT "what's the best spend management tool for marketing agencies," the model does not serve a ranked list of pages. It synthesises an answer and names brands it considers authoritative. Your job is to be one of those brands.
The Core Distinction
SEO | AEO | |
|---|---|---|
What it wins | Google blue-link rankings | AI citations and recommendations |
Primary signals | Backlinks, keywords, page authority | Structured data, citation footprint, entity consistency |
How buyers find you | They click your link from a results page | The AI names you in its answer |
Content structure | Optimised for keyword relevance | Optimised for direct-answer extraction |
Measurement | Rankings, organic traffic, clicks | AI visibility score, share of voice across LLMs |
The overlap is real. High-quality content, E-E-A-T signals, and a well-structured site help both. But the execution is different enough that treating them as the same discipline is where most companies go wrong.
Why B2B Companies Should Prioritise AEO Right Now
The data on B2B buyer behaviour in 2026 makes the case clearly.
51% of B2B buyers now start their research with AI before Google, up from just 29% seven months earlier, according to G2's March 2026 Answer Economy Report. That is not a trend line. That is a structural shift that happened faster than most marketing teams adjusted.
And the stakes are high. Forrester research found that B2B buyers use AI tools to compare vendors against each other (55% of buyers) and build internal business cases before engaging any vendor (47% of buyers). These are not peripheral tasks. They are the activities that determine whether you get on the shortlist at all.
A March 2026 analysis of 680 million citations by Averi found that AI search traffic converts at 14.2%, compared to Google organic's 2.8%. That is a 5.1x conversion advantage. Claude users convert at 16.8%, ChatGPT at 14.2%, Perplexity at 12.4%. The conversion data makes the ROI case clear.
Who Should Prioritise AEO First
Not every business has the same urgency. Three categories have the highest immediate exposure:
B2B SaaS. Buyers use ChatGPT and Perplexity to compare features, generate shortlists, and draft RFPs before visiting any vendor site. If your product is not being cited, you are not on the list.
Professional services (consultants, agencies, advisors). AI citation functions as the new word-of-mouth recommendation. Being named when someone asks "best [service type] for [use case]" is the equivalent of ranking on the first page of Google five years ago.
Fintech. Financial product buyers are conducting deep research before any vendor contact. The Gartner data cited above found buyers spend 27% of their total buying time on independent research, and just 5 to 6% of that time with any single vendor. That research is increasingly happening inside AI tools.
The uncomfortable truth: only 22% of marketers currently track AI visibility. Your competitors probably are not optimising for this either. That window will not stay open.
Where SEO and AEO Overlap (and Why You Still Need Both)
AEO is not a replacement for SEO. It is an extension of it, applied to a new class of search interface where the engine synthesises answers rather than listing links.
The disciplines share a foundation. Content quality matters for both. E-E-A-T signals — demonstrating genuine expertise, experience, authoritativeness, and trustworthiness — matter for both. A technically broken website hurts both. These are not competing investments; they are layered ones.
Where They Diverge in Practice
The divergence shows up in execution. An SEO-optimised article might bury its main argument three paragraphs in after an introductory section designed to satisfy keyword density. An AEO-optimised article puts the direct answer in the first 100 words, because that is where LLMs look first. An SEO strategy pursues backlinks from high-authority domains. An AEO strategy pursues third-party citations: Reddit threads, directory listings, mentions in trade publications, and structured data that tells AI engines exactly who you are and what you do.
The practical implication: most companies with an existing SEO programme have content that ranks but does not get cited. The articles exist. The domain authority exists. But the structure is wrong for AI extraction, the schema is missing, and the third-party footprint is thin. Fixing that is AEO work — and it builds on, rather than replaces, the SEO foundation.
The core principle: SEO earns you a seat on the results page. AEO earns you a name in the answer. For B2B buyers who have already decided before they visit your site, the name in the answer is worth more.
A Budget Allocation Framework for 2026
The right split depends on your current state and your buyer behaviour. Here is a practical starting framework.
If you have an established SEO programme and are new to AEO
Your SEO foundation is an asset. Do not abandon it. But shift incremental budget toward AEO rather than doubling down on a channel your buyers are increasingly bypassing.
A reasonable starting allocation: 60% SEO / 40% AEO, moving to 50/50 within 12 months as you measure AI-sourced lead volume and adjust based on what is actually driving pipeline.
If you are starting from scratch
Build the AEO technical foundation first. Schema markup, structured data, entity consistency, and an llms.txt file are table-stakes infrastructure. None of it requires a developer with months of runway. Four files. A few days of work. Everything else compounds on top.
Then build content in parallel for both channels — but structure every piece for AI extraction first, Google ranking second. The two goals are compatible; the prioritisation just needs to shift.
If your buyers are clearly using AI to find vendors
You already know the answer. Go AEO-heavy now. The G2 data is specific: 69% of buyers chose a different vendor than they initially planned, based on AI guidance. If your buyers are in that pool and you are not being cited, you are losing deals to companies that are.
The signal to watch: ask every new lead "how did you hear about us?" If you start seeing ChatGPT, Perplexity, or Google AI Overviews in the answers, your buyers are already using AI. You just do not have visibility into it yet.
Frequently Asked Questions
Can I do AEO without doing SEO?
Technically, yes. Practically, the two are hard to fully separate. A website with no domain authority, no indexed content, and no backlinks will struggle to build the citation footprint that AI engines require. That said, the AEO technical layer — schema markup, entity consistency, structured content, third-party directory placements — can be built independently of SEO and will generate AI visibility gains on its own. If you have to choose one to start, and your buyers are B2B, start with AEO. The conversion rate advantage (14.2% vs 2.8% for Google organic) makes the ROI case clear.
Does AEO hurt my Google rankings?
No. The changes that improve AI visibility — clearer content structure, faster direct answers, better schema markup, improved entity consistency — are also positive signals for Google. There is no known trade-off. You are not choosing between them; you are choosing how to prioritise your time and budget.
How do I know if my buyers are using AI to find vendors?
Three ways to check. First, add a "how did you hear about us?" field to your intake form and look for AI tools in the responses. Second, run the prompts your buyers would run — "best [category] tool for [use case]" — in ChatGPT, Perplexity, and Google AI Overviews, and see if you appear. Third, look at your Google Search Console data for traffic from AI Overviews referrals. If you are not tracking AI-sourced traffic at all, you are making budget decisions with incomplete information.
Should I do AEO in-house or hire an agency?
The honest answer depends on your team's existing capabilities. The technical foundation — schema, llms.txt, entity audits — can be done in-house if you have someone who understands structured data. The content and citation-building work (Reddit presence, directory placements, third-party publication mentions) is more time-intensive and benefits from specialised execution. Most B2B companies find that the technical layer is manageable in-house, while the ongoing citation footprint work is where agency support pays for itself.
Where to Start
The buyers who are going to contact you next month are researching right now. Some of them are asking ChatGPT which vendors to consider. Some are using Perplexity to compare your category. Some are running Deep Research reports that will determine which three companies make their shortlist.
If your brand is not in those answers, it does not matter how well you rank on Google.
The first step is knowing where you actually stand. Not guessing. Not assuming your SEO rankings translate to AI visibility. Actually checking — across ChatGPT, Perplexity, Google AI Overviews, and Gemini — which prompts your buyers are running and whether you appear.
That is exactly what an AEO audit tells you. We run the prompts your buyers use, map your current AI visibility score, identify the gaps your competitors are filling, and give you a clear picture of what it would take to show up.
