GEO vs traditional SEO: what changes for a mid-market B2B company?

By Olly, founder of AEOscore, AEO consultant and full-stack developer, 20+ years in search10 min read

Traditional SEO earns your pages a ranking in a list of links a buyer clicks. Generative engine optimisation (GEO) earns your business a mention, and ideally a citation, inside the answer an AI assistant writes. For a mid-market B2B company the work overlaps, but the queries, measurements and deliverables change.

The one-line version: SEO earns a link a buyer clicks; GEO earns a mention inside an answer the buyer may never click through.

This guide is for a marketing team of roughly 2 to 15 people: what changes, what honestly stays the same, how you measure it, and what to do in the first 90 days. The full definition of the discipline lives in our answer engine optimisation deep dive; this page is about the difference in practice.

Side by side

How does generative engine optimisation differ from traditional SEO?

Traditional SEO optimises a page so it ranks in a list of links a buyer clicks, while generative engine optimisation optimises your information so an AI assistant names and cites you inside the answer it writes, which means success is measured in mentions and citations rather than rankings and sessions.

Traditional SEOGEO
GoalA ranking on a results page, and the click that followsA mention, and ideally a citation, inside the AI-written answer
What you optimisePages, keywords, internal links, site healthQuotable answer passages, consistent entity facts, and the third-party sources engines read
What a query looks likeHead terms: “crm software uk”Conversational buyer questions: “which CRM suits a 50-person UK manufacturer that outgrew spreadsheets?”
Where authority comes fromBacklinks, domain history, technical healthCorroboration: the same facts about you on your site, directories, review sites and forums, linked or not
How you measure itRankings, sessions, click-through rateMention rate, citation rate, share of voice and sentiment, reported per engine
How fast it movesMonths for competitive termsTypically four to twelve weeks per fix, and unevenly: one engine moves weeks before another
Who does the workAn SEO agency or in-house SEOWhoever owns organic growth, plus a technical pair of hands for site-level changes

A note on the name: GEO, AEO, AIO and GAIO all describe the same discipline, with GEO more common in American writing and AEO gaining ground in the UK. We use AEO across this site; the naming soup has its own glossary entry.

The deliverable changed: with GEO you are buying sentences an engine repeats to your buyers, where SEO bought you a ranking and a click.

The honest part

Is GEO replacing SEO for B2B companies?

No: GEO sits alongside SEO, because AI engines still draw heavily on crawled, indexed web pages, so a mid-market B2B company that abandons SEO usually loses AI visibility as well.

Google’s own documentation says AI Overviews and AI Mode are built on the same crawled, indexed web as classic Search (Google), and the other engines run their own crawlers over the same pages. So a large part of what your SEO budget already buys still counts. What stays the same:

Crawlability

AI engines are built on crawled pages. A site GPTBot or Google-Extended cannot reach is invisible to the answers, exactly as a blocked site is invisible to search.

Page speed and clean HTML

Engines retrieve and parse pages on a budget. Server-rendered content that loads fast gets read; content that only appears after JavaScript often does not.

Real expertise

The passages engines quote are the ones with a named author, a specific claim and a date. Thin content fails in AI answers for the same reason it fails in search.

Content that answers real questions

Useful pages win in both systems. GEO changes the shape of the page, not the requirement to know what you are talking about.

Third-party mentions

Off-site reputation mattered for rankings and matters at least as much for answers, because engines assemble answers from other people's pages as well as yours.

If a vendor tells you SEO is dead and GEO replaces it, they are selling the rebrand rather than the work.

In practice

What changes day to day for a mid-market B2B marketing team?

You stop tracking a keyword list and start tracking a set of real buyer questions across six engines, you write pages that answer a question in the first 50 words rather than building to the answer, and you spend more time on off-site mentions because AI answers are assembled from third-party sources as well as your own site.

Longer, conversational buyer prompts replace head keywords

Buyers describe their situation to an assistant in a sentence or three, so the unit you track is a real question, not a two-word term.

Discovery happens earlier in the buying cycle

The shortlist forms inside the first answer, before a website visit. If you are not in that answer, you were never considered.

Six engines give six different answers

ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews and AI Mode each draw on different sources and disagree routinely, so each needs its own line in the report.

There is no rank to report to your board

The board slide changes from positions and sessions to mention rate, citation rate and share of voice against named competitors.

Sentiment matters as much as presence

An answer can name you and describe you sourly or inaccurately. How the engine talks about you becomes a number worth tracking.

The scale of the shift, with dates:

  • US Google users clicked a traditional result on 8% of visits when an AI summary appeared, versus 15% without one (March 2025, Pew Research Center).
  • 51% of B2B software buyers now start vendor research in an AI chatbot (survey of 1,076 buyers, March 2026, G2 via G2), and 94% of business buyers report using AI somewhere in their buying process (Forrester, January 2026).
  • In our own study of 304 hand-written UK B2B queries across eight sectors, 216 (71%) returned a Google AI Overview on 17 August 2026, including 29 of 48 (60%) commercial supplier-intent queries (AEOscore).
  • The engines also disagree with themselves: when we asked one B2B buyer prompt 20 times each on ChatGPT and Gemini on 20 August 2026, no two of the 40 runs returned the same brand list (AEOscore).

Measurement

How do you measure GEO when there are no rankings?

You measure mention rate (how often you are named), citation rate (how often your site is linked as a source), share of voice against named competitors, answer position (whether you are first-named), and sentiment (whether the description is favourable).

Mention rate

How often the engines name your business across a fixed set of buyer questions. The nearest thing GEO has to a visibility number.

Citation rate

How often your site is linked as a source the answer was built from. Stronger than a mention: the engine treated your page as evidence.

Share of voice

Your slice of every brand mention in the tracked answers, against named competitors. Zero-sum: your share only rises if someone else's falls.

Sentiment

Whether the description attached to your name is favourable, neutral or sour. Two brands can be mentioned equally often and recommended very differently.

A fifth is worth tracking once the first four are in place: answer position, whether you are the first business named or an afterthought at the end of the list. The full measurement method, the formula for share of voice with a worked example, is in our share of voice guide, and the complete reporting framework for boards and clients is in the AEO KPIs and client reporting guide. The point for this page: all five numbers are per engine, per question, and none of them is a ranking.

Inputs

Does GEO need different content from SEO content?

Yes in structure, no in substance: the same expertise works, but it has to be written in self-contained, quotable chunks with the direct answer at the top, clear entity naming, real prices and real dates, because an engine lifts a passage rather than ranking a page.

The practical test: could an engine lift any 50-word passage from your page and have it stand alone as a correct, dated, attributed answer? Most B2B pages fail that test not because the expertise is missing but because the answer is buried under three paragraphs of scene-setting. The rewrite is usually restructuring, not new research: direct answer first, one question per section, your company named in full, real prices and real dates on the page.

Do backlinks still matter for GEO?

Links still matter for being crawled and trusted, but unlinked mentions on the sources an engine already cites, such as roundups, review sites, industry directories and forum threads, often influence AI answers more directly than a single high-authority backlink would.

Reading the citations on the answers you are losing tells you exactly which sources to win; our tip on answering the thread AI cites is the playbook for the forum half.

A typical mid-market fix list is half technical: crawler rules, answer blocks, page structure, llms.txt. Very little of it is new blog posts.

The plan

What should a mid-market B2B team do in the first 90 days?

Baseline what the engines say now, unblock the AI crawlers, freeze a list of real buyer questions, rewrite your key pages answer-first, make your facts agree everywhere, win two or three off-site placements, then re-ask the same questions on a schedule and log what moved.

  1. 1. Get a baseline before you change anything

    Ask your real buyer questions across all six engines and record who is named, who is cited and how you are described. This is the free starting point; without it you cannot show movement later.

  2. 2. Check the AI crawlers can reach your site

    Robots rules and firewall settings block AI crawlers on a surprising share of B2B sites, sometimes by default. Five minutes with a robots checker settles it, and it is the cheapest fix on this list.

  3. 3. Write down 25 to 40 real buyer questions and freeze the list

    Problem descriptions, category questions, comparisons and direct asks, in your buyers' words. Frozen, because a changing list makes every later number incomparable.

  4. 4. Rewrite your most important pages answer-first

    Direct answer in the first 50 words, one question per section, real prices and real dates, your company named in full. Start with the five pages closest to your buyer questions.

  5. 5. Make your facts agree everywhere

    Same company description, prices and claims on your site, your directories and your review profiles. Engines cross-check sources, and disagreement reads as unreliability.

  6. 6. Win two or three off-site placements

    Read the citations on the answers you are losing, then get into those exact sources: the roundup that lists your rivals, the directory the engines lean on, the forum thread doing the recommending.

  7. 7. Re-ask the same questions on a fixed schedule

    Weekly, same day, fresh sessions, several runs per question. Log mention, citation and position per engine so each shipped fix has a before and an after.

Step 1 is free: the free AEO score runs the baseline across all six engines. Step 2 takes five minutes with the AI robots checker. The same 90 days as a week-by-week working relationship is on the mid-market marketing teams page.

Expectations

How long does GEO take to show results?

Most changes surface in AI answers four to twelve weeks after they go live, because engines re-crawl, re-index and refresh their retrieval sources on their own schedule.

Movement is uneven by design: engines that ground answers in live retrieval respond weeks before engines answering from training memory, so it is normal to be named in Perplexity and Gemini while ChatGPT still overlooks you. Judge the work by re-asking the same questions on a schedule and logging mention, citation and position per engine, never by watching traffic to the page. How we produce every number, and where the method runs out, is on the methodology page.

Most GEO best practice sold in 2026 is untested. We publish our methodology and measure every fix, because in a field this young, evidence beats confidence.

Budget

What does GEO cost on top of an SEO budget?

In the UK, AI visibility monitoring software typically costs £50 to £250 a month and a service that makes the changes for you £1,500 a month or more, and most mid-market B2B teams keep their existing SEO budget and add this as a separate, smaller line.

The SEO budget keeps earning the crawled, trusted pages the engines draw on; the GEO line pays for knowing which answers you are missing and for the hands that fix them. Our own pricing in one line: £395 one-off AI Visibility Audit, credited against your first month, £99 a month Monitor, £1,495 a month Monitor + Strategist. The detail, and how it compares with the rest of the UK market, is on the pricing page.

Ownership

Who should own GEO in a mid-market B2B company?

Whoever owns organic growth should own it, but it needs a technical pair of hands, because a large share of the fixes are site-level changes to crawler rules, page structure and answer blocks rather than new blog posts.

Should we buy a GEO tool or a GEO service?

A tool tells you which answers you are missing, a service changes the pages and the off-site sources so those answers move, and mid-market teams with fewer than three people in-house usually need both.

The split between tools that report and services that fix, with the hours each costs you, is examined properly in monitoring vs fixing, and who does the implementation when it is done for you has a plain answer of its own. AEOscore is built as both halves: the software finds the gaps, and on the top tier a named person makes the changes and shows the before and after. Those changes include the traditional SEO checks and fixes, so the groundwork is covered rather than assumed; the plan detail is on the pricing page.

FAQ

GEO vs SEO: common questions

Do GEO, AEO, AIO and GAIO mean different things?
No: they are competing labels for the same discipline of earning presence in AI-generated answers, with GEO more common in American writing and AEO gaining ground in the UK, so judge a vendor by what they measure and change, not by the acronym.
Will optimising for AI answers hurt our Google rankings?
No: the overlap, crawlable pages, direct answers, real expertise and third-party mentions, is exactly what Google's own guidance rewards, so GEO work done properly tends to help rankings rather than harm them.
Can our existing SEO agency handle GEO?
Ask them three questions: which engines they measure, whether they can show you the actual answers their numbers come from, and who makes the site-level fixes; an agency that can answer all three can do the work, whatever they call it.
Does GEO work for niche B2B categories?
Usually better than for broad ones: niche buyer questions are lightly contested, so a handful of well-corroborated pages and placements can make you the name the engines reach for.
What is the fastest first GEO win for a B2B site?
Check that AI crawlers can actually reach your site: robots rules and firewall defaults silently block them on a meaningful share of B2B sites, and unblocking is a five-minute fix with an immediate effect on what engines can read.
Should we report GEO numbers alongside SEO numbers?
Yes, on the same monthly page but on separate lines per engine, because a blended average hides which engine you are losing and rankings tell you nothing about answers.
Does AEOscore's Monitor + Strategist plan include traditional SEO work?
Yes: the checks and fixes the strategist ships cover the traditional SEO groundwork, crawler access, page structure and headings, titles and metadata, internal links and structured data, done as part of the same day rather than sold as a separate retainer.
