SEO vs AEO vs GEO: what is actually different

SEO helps your page appear in traditional search results. AEO helps your information appear as a direct answer in search features or answer engines. GEO helps your business or content get mentioned, summarised or cited in AI-generated answers. In practice, the same strong page can support all three.

The main difference is where the reader ends up

SEO usually sends someone to a page on your website. AEO often gives them an answer before they click, such as a featured snippet, People Also Ask result or voice assistant response. GEO can send them to your site, but the reader may first encounter your business inside an answer from ChatGPT, Google AI Overviews, Perplexity or another generative system.

The boundaries are not official. Google does not publish a formal definition of AEO or GEO, and marketers use the terms differently. Here, AEO means optimising for direct answers, while GEO means improving the chance that generative AI systems use or mention your information.

Here is what SEO, AEO and GEO each optimise

The table shows the practical difference between the three terms. The work in the final column is the part that is most specific to each one, not a complete list of everything you may need to do.

| Area | SEO | AEO | GEO | |---|---|---|---| | **What it optimises for** | Rankings and qualified organic visits | A clear, extractable answer to a specific question | Being selected, summarised, cited or recommended in an AI-generated answer | | **Where the result appears** | Google or Bing results pages, usually as a blue link or rich result | Featured snippets, People Also Ask, voice assistants and answer-focused search features | ChatGPT, Google AI Overviews, Perplexity, Claude and other generative interfaces | | **How you measure it** | Rankings, impressions, clicks, organic traffic, leads and sales | Answer visibility, featured snippets, question-level rankings, clicks and assisted conversions | Mentions, citations, linked references, inclusion in relevant prompts and resulting traffic or enquiries | | **What work is unique to it** | Technical access, search intent mapping, internal links, authority and sustained content improvement | Writing concise answers, matching question formats and making facts easy to extract | Building consistent entity information, earning trusted third-party references and testing how systems describe you |

Most of the work is shared

Around 80% of the work is shared across SEO, AEO and GEO. You still need pages that search engines and AI systems can access, understand and trust. You still need to explain one subject clearly, use the words customers use and support claims with specific facts.

• Crawlable pages that do not block important content from search engines.
• Clear page titles and headings that describe the subject accurately.
• Specific facts such as prices, service areas, opening hours, qualifications and delivery times.
• Simple page structures with one main question or purpose per page.
• Useful internal links that show how related pages fit together.
• Consistent business details across your website, directories and trusted third-party sites.
• Evidence, examples and sources where a claim needs support.

A plumber in Leeds does not need three separate versions of a page for “boiler repair Leeds”, “Can you repair a broken boiler?” and “Who is a reliable boiler repair company in Leeds?” One well-written service page can target the search, answer the question and give an AI system reliable material to summarise.

SEO still covers the foundation

SEO is the broadest term because it covers the conditions that help a website appear in traditional search. It includes technical access, useful content, page relevance, links between your own pages and signals of reputation from other sites.

Suppose a barber shop wants to appear for “men’s haircut near me” and “skin fade price Bristol”. It needs a crawlable location page, a visible price, an address that matches its Google Business Profile, photographs or examples of its work, and a clear way to book. Adding the phrase “premium grooming solutions” will not replace those basics.

SEO is also the area with the clearest business measures. Track impressions and clicks in Google Search Console, organic sessions in analytics, calls and bookings, and the revenue linked to those leads. Rankings can help diagnose a problem, but a position number is not the business result.

AEO makes answers easier to extract

AEO focuses on whether a system can find a short, accurate answer to a question and show it directly. The useful change is usually not a new technology. It is clearer writing.

For a mortgage broker, a page might answer “How much deposit do I need for a first-time buyer mortgage?” in the first two sentences, then explain exceptions, costs and examples. A heading such as “How much deposit do first-time buyers need?” gives both the reader and the search system a strong clue about the page structure.

Use question-led headings where they match real searches. Put the direct answer near the heading. Add definitions, steps, tables or examples underneath. Structured data can help systems interpret a page, but it does not guarantee a featured snippet or voice result. Google decides what to display.

GEO depends more on reputation and consistency

GEO is about making your business or source easy for generative systems to identify, verify and use when producing an answer. That depends on your own pages, but also on what reliable external sources say about you.

For example, an AI system answering “Which accountants in Manchester work with small construction firms?” may combine an accountant’s website with professional directories, reviews, local publications and other references. A vague services page gives it little to work with. A page that names the industries served, locations covered, qualifications, typical fees and client examples provides stronger material.

Keep your organisation name, address, services, people and specialisms consistent. Seek legitimate mentions in industry publications, associations and local sources. Do not create fake profiles or dozens of low-quality directory listings. AI systems can change, their sources are not fully visible, and no one can promise inclusion for a particular prompt.

The measurements are useful but not interchangeable

SEO, AEO and GEO need different reports because visibility in a link, an answer box and an AI response are different outcomes. A single traffic number will miss some of the picture.

• For SEO, review non-brand clicks, enquiries, sales and the queries bringing qualified visitors.
• For AEO, record which questions produce a featured snippet, People Also Ask result or other answer feature, then check whether visibility leads to visits or conversions.
• For GEO, test a fixed set of realistic prompts each month and record whether your business is mentioned, how it is described, which sources are cited and whether the details are correct.
• For all three, check revenue, calls, bookings and other meaningful actions rather than treating impressions as success.

GEO testing is especially imperfect. ChatGPT, Google AI Overviews and Perplexity may produce different answers for the same question, and results can vary by location, account, date and wording. Treat prompt checks as evidence of visibility, not as a universal ranking report.

Do not buy three tools because there are three acronyms

Most small businesses do not need one SEO tool, one AEO tool and one GEO tool. They need a reliable website, search data, a way to track enquiries and a manageable process for improving important pages.

Many products use the new labels to package familiar features: keyword research, content briefs, rank tracking, schema checks or brand monitoring. Those features may be useful, but the acronym on the pricing page does not make the work different. Ask what data the tool adds, what decision it helps you make and whether you will use it every month.

A tool such as Google Search Console can show queries, impressions and clicks. Analytics and call tracking can connect visits to outcomes. A spreadsheet can record how often a set of AI prompts mentions your company. If updating pages is the bottleneck, a system such as RubyFlow may help keep website copy aligned with the language customers use, but it is not a replacement for judgement or customer evidence.

Use this order of operations when time is limited

Start with the work that improves every type of visibility, then add the narrow activities that match your business goal.

1. 1.Fix access and accuracy. Make sure important pages can be crawled, work on mobile, load acceptably and show the correct phone number, address, services, prices and opening hours.
2. 2.Choose the pages closest to revenue. A service page for “emergency electrician in York” usually matters more than a general blog post about electricity.
3. 3.Match real questions. Use Search Console, sales calls, customer emails and tools such as Google autocomplete to find the wording people actually use.
4. 4.Write direct answers and useful detail. State the answer early, then add examples, limits, costs, steps and evidence.
5. 5.Measure business outcomes. Track calls, forms, bookings and sales alongside clicks and impressions.
6. 6.Add AEO checks if direct answers matter. Review question headings, concise responses and suitable structured data, without assuming a snippet is guaranteed.
7. 7.Add GEO checks if AI recommendations matter. Keep facts consistent and monitor a small, repeatable set of prompts and third-party references.

For most companies, this order is enough. Improve the page a customer needs, make its facts clear, and measure whether it creates business. The labels can help you describe the destination, but they should not dictate three separate content programmes.
