SEO vs AEO vs GEO: what a small business actually needs

What is the difference between SEO, AEO and GEO?

The labels describe where a customer sees you, not three different websites. SEO works on the classic results page: a ranking, a snippet, a click. AEO aims to make your page the quoted direct answer — a featured snippet, a voice reply, the lead source under an AI Overview. GEO aims to get your business named or linked in a reply a model writes: ChatGPT search, Perplexity, Copilot, Google AI Mode or Yandex’s Alice AI.

The term GEO comes from a 2023 research paper (KDD 2024) that reported visibility gains of up to 40% in its own benchmark: a lab result, not a forecast for your website.

Does a small business need separate AEO or GEO work at all?

Mostly not. Google’s guide to its generative AI features, updated 10 July 2026, says they rest on the core Search ranking and quality systems: the model retrieves pages from the index and runs its own related “fan-out” searches. A page must be indexed and eligible for a snippet before it can appear in AI Overviews or AI Mode. In Google, AEO and GEO sit on top of SEO, not beside it.

The same guide lists what you can ignore: llms.txt and other AI-only files, chunking content, rewriting copy for machines, chasing inauthentic mentions and special schema. Structured data still makes pages eligible for rich results; it is not a key to AI answers. Other engines add checks, not a new discipline:

• ChatGPT: sites that block OAI-SearchBot in robots.txt are not shown in ChatGPT search answers; blocking GPTBot only opts you out of model training.
• Bing: citations in Copilot are reported in Bing Webmaster Tools, and Bing asks local businesses to keep Bing Places current.
• Google: Search Console’s Search generative AI setting includes your site by default; excluding it removes you from AI Overviews and AI Mode.

The genuinely separate part is measurement: whether you are cited, and who is cited instead of you. For a small firm that is an hour a month, not a retainer.

What comes first for a local service, an online store, a B2B firm or a multilingual site?

The order depends on where AI answers take their facts about you.

A rule of thumb: if Search Console shows more pages not indexed than indexed, nothing sold as AEO or GEO is your first problem.

How much should each step cost: DIY, a snapshot or an audit?

Spend in proportion to what you don’t know. If you know what is broken, pay for the fix; if you don’t, pay for the smallest diagnosis that will tell you.

AI-assisted means AI drafts and a person directs and checks; human-led means a specialist does the work and AI assists. In a crowded local market choose human-led: reading competitors is where a person’s judgement counts most.

What can you check yourself in 30 minutes?

You need Search Console, Bing Webmaster Tools and your Business Profile. Nothing here costs money.

1. Search Console Performance — 5 minutesSort three months of queries by impressions and note the top ten. Many impressions and almost no clicks mark an AEO candidate: the answer may already sit on the results page. Check whose.
2. Pages report — 5 minutesCompare indexed with not indexed pages and read the main reason.
3. Generative AI report — 5 minutesImpressions in AI Overviews and AI Mode by page, country, device and date; no query tab. Google had opened it to every site by 31 August 2026, so an empty report usually means too few impressions. Confirm Settings → Search generative AI includes your site.
4. Bing AI Performance — 5 minutesShows citations in Copilot and Bing’s AI summaries, plus a sample of grounding queries: the phrases the AI used to find your pages.
5. robots.txt — 2 minutesOAI-SearchBot must not be disallowed. Blocking GPTBot is a training choice, not a search one.
6. Ten prompts — 5 minutesAsk ChatGPT, Perplexity, Copilot and AI Mode what customers ask: “Which [service] in [city] would you recommend?”, “How much does [service] cost in [city]?”. Log who is named and linked.
7. Business Profile — 3 minutesMatch hours, services, phone and address against the website. A mismatch is the cheapest fix on this list.

What do real Search Console numbers look like?

Our own site, viton13.com (INTERNAL), is the warning case. On 21 August 2026 Google counted 738 pages indexed and 2,572 not indexed; the 28 days from 30 July to 26 August brought 69 clicks from 17,373 impressions. The first job was plain technical SEO — 1,008 retired URLs now answer 410 Gone and 141 permanent redirect rules sit in one map — because a page outside the index cannot be a source for any AI answer.

The opposite case, a client site built with indexing in mind from day one, is SB Excursions in the example below.

Which AEO and GEO offers should a small business turn down?

• Citations promised by a date. No engine offers a way to book an organic citation.
• llms.txt as the fix. Google says its Search, AI features included, does not use it.
• “AI-ready” rewrites or chunking of every page. Google says neither is needed.
• Manufactured mentions: paid forum posts, fake reviews, link-farm “citations”. Google says chasing inauthentic mentions is less helpful than it looks, and its AI features sit on the same systems that filter spam.
• Pages written for every fan-out query. Google calls that scaled content abuse.
• A schema package sold as AI ranking. Google says its AI features need no special markup.
• A monthly “AI visibility score” with no baseline. If it does not name the prompts, engines and dates, you cannot check it.

Worth paying for: fixing indexing, pages built on first-hand facts and a baseline you can re-run yourself.

When is a Search Snapshot worth paying for, and when is it not?

Skip it if the self-check already answered the question: with most pages unindexed, go to a technical SEO audit; with rankings but no enquiries, fix the offer through Audit & Positioning. Buy the snapshot when the free reports contradict what customers tell you, or when you cannot name the three competitors who appear instead of you. You get one page to act on, not a plan you must buy next.
