SEO vs AEO vs GEO: What Should Brands Optimise for Now?

Search has changed significantly over the past few years. Before, when someone searched a keyword like “SEO vs AEO vs GEO,” search engines like Google displayed a ranked list of webpages. Users had to click through different results to find the information they needed.

Today, a Google search can show an AI-generated overview at the top of the page. This provides summarised information from multiple sources before showing traditional rankings.

Some people skip Google altogether and go straight to AI platforms such as Claude, ChatGPT, Grok, and Perplexity when they need answers. These changes are why we now use new optimisation tactics like AEO and GEO alongside traditional SEO.

Keep reading to learn more about these terms, why they matter, and how you can improve visibility with all three.

Key Takeaways

• SEO improves your website’s visibility in traditional search results and helps search engines understand your content.
• AEO structures content so search engines and answer systems can easily extract direct responses.
• GEO boosts your chances of being mentioned or cited in AI-generated responses.
• The best search strategy combines SEO, AEO, and GEO instead of treating them as separate tactics.
• Helpful, authoritative, and well-structured content is a common factor behind all three.

What Is SEO?

SEO (Search Engine Optimisation) is the process of improving your website so search engines can find, understand, and rank your content. For decades, it has been the foundation of online visibility.

The goal is to earn a strong position in the list of blue links in traditional search results like Google or Bing. For example, when someone searches “best email marketing tools for small businesses," SEO determines which pages appear at the top of the results.

According to a 2026 report by First Page Sage, the top three organic search results get about 77% of all clicks that still go to traditional organic listings. The rest of the attention is increasingly going to AI answers and other SERP features.

How Does SEO Work?

Search engines follow a simple process to understand and rank content.

• Crawling: Search engines discover webpages by following links across the internet.
• Indexing: They store and organise information from those pages in a massive database called an index.
• Ranking: When someone searches, algorithms analyse indexed pages and display the results most likely to answer the query.

Is SEO Still Relevant in 2026?

Yes, SEO is still relevant in 2026.
With the rise of AI search, some marketers wonder if traditional SEO is becoming outdated. After all, users can now receive answers directly from AI-generated summaries without clicking through to websites.

Even research from First Page Sage reported that 81.6% of U.S. Google queries get AI-generated responses. It also found that ranking organically in position one is now worth 84% less when an AI response appears for that query.

So why bother with SEO?

The short answer is that SEO still matters because AI systems need reliable information. AI doesn’t create answers out of thin air. It first needs trustworthy information. Much of that comes from websites that already demonstrate strong SEO signals.

So SEO doesn’t get replaced by AEO or GEO. Instead, it enables them. In fact, after analysing 25,000 queries across ChatGPT, Perplexity, and Google AI Overviews, ZipTie discovered that a website ranking #1 on Google’s SERPs has a 25% chance of appearing as a source for AI responses.

However, ranking on Google isn’t the only factor that determines AI visibility. AI systems often expand a user’s question into multiple related searches before generating an answer. This process, sometimes called query fan-out, allows AI tools to gather information from different sources.

As a result, a page outside the traditional top search results can still appear in AI responses if it provides valuable information for a related subtopic. This is why brands should focus on building topical authority instead of simply optimising for a specific keyword.

How to Improve SEO

Improving your website’s SEO requires a combination of technical optimisation, content quality, and authority building.

Here are some effective ways to boost search engine rankings:

• Improve website speed, mobile usability, and technical performance.
• Create a clear site structure that helps users and search engines navigate your content.
• Fix broken links and strengthen internal linking.
• Earn backlinks from trustworthy and relevant websites.
• Create content that matches search intent and fully answers user questions.
• Build topical authority by publishing related content around important subjects.
• Update older content when information changes.
• Use relevant keywords naturally in your headings and content.

Pro Tip: SEO is not about adding as many keywords as possible. Search engines increasingly reward content that helps people. So always prioritise clarity and usefulness over keyword stuffing.

What Is AEO?

AEO (Answer Engine Optimisation) involves structuring your content so search engines and answer systems can extract a self-contained answer and present it directly to users.

With traditional SEO, the goal is to rank your article on the first page of search results so people click through to your website. However, for AEO, you want the system to pull a clear answer from your content and display it in search results.

For example, Google may use your content to answer questions in:

• Google Featured Snippets
• People Also Ask (PAA) boxes
• AI Overviews

AEO content can also appear in voice assistant answers such as Siri and Alexa.

Many of these features answer a user’s question without requiring them to click a website. That means visibility has shifted from simply ranking in organic search results to providing direct answers that search engines can display.

Why Does AEO Matter?

AEO matters because search behaviour has changed. Instead of clicking through several search results, many people scan AI overviews, featured snippets, or PAA boxes before deciding whether to visit a website. Others simply accept the answer they see.

This shift has led to more “zero-click” searches, where users get the information they need without opening a page.

When your content appears in these answer features, your brand gains visibility and credibility, even if users don’t immediately click through.

How To Improve AEO

If you want search engines to choose your content as the answer, focus on clarity and structure.

• Use question-based headings that match what people actually search.
• Lead with a direct answer. If the heading is “What is content marketing?”, the first paragraph must provide a clear answer.
• Add FAQ sections that mirror real users' questions.
• Break information into short paragraphs, lists, and tables where appropriate.
• Use schema markup, especially FAQ, HowTo, and article schema where relevant.
• Keep answers clear, factual, and easy to understand.

Pro Tip: Write for people first. If a reader can quickly find and understand the answer, answer engines can too.

What Is GEO?

GEO (Generative Engine Optimisation) is the practice of making your content easier for generative AI tools such as ChatGPT to understand, trust, and reference when generating answers.

To understand GEO, it helps to understand how AI search typically works.

When you ask a generative AI tool a question, it may use information from its existing knowledge or retrieve information from the web. What it does depends on the tool, your question, and the search features available.

When web search is involved, the system typically:

1. Interprets your question to understand what information you need.
2. Retrieves relevant information from websites and other sources.
3. Evaluates and synthesises information from those sources.
4. Generates an answer based on the information it considers relevant, sometimes with links or citations to its sources.

For example, someone might ask:

“What are the best content marketing agencies in the United States?”

The AI may review dozens of websites before generating one answer. What GEO does is increase the chances that your company is in that response.

Why Does GEO Matter?

GEO matters because more people now use AI assistants for research, product comparisons, and recommendations. Another First Page Sage report indicates that ChatGPT accounts for approximately 17.9% of total digital queries.

If your brand isn’t part of the information AI systems understand and trust, you become less visible in these new search experiences.

How to Improve GEO

AI systems are more likely to reference content that is original, trustworthy, and consistently accurate.

To improve your visibility across AI tools:

• Publish original research, case studies, expert opinions, and first-hand experience. Essentially, utilise authority signals (E-E-A-T).
• Keep your content updated as information changes.
• Maintain consistent brand information across your site.
• Earn mentions and backlinks from reputable websites.
• Use structured data appropriately.
• Address the detailed questions your target audience actually asks, including complex or multi-part queries.
• Write clearly so both people and AI systems can easily understand your content.
• Create comprehensive content around the subjects your brand is known for.

Pro Tip: AI systems favour original information that cannot be easily found elsewhere.

SEO vs AEO vs GEO Comparison

The difference between SEO vs AEO vs GEO is straightforward. They all improve online visibility, but they focus on different search experiences.

SEO earns a ranked position in a list of links.

AEO focuses on making your content easy for search and answer engines to use when providing direct answers.

GEO helps with visibility in AI-generated responses.

Here’s a comprehensive comparison.

AEO vs SEO

Although AEO builds on many SEO best practices, they have different goals. SEO focuses on ranking the full page so people click through from the results list. AEO, on the other hand, makes your content ready for systems to lift and show as the answer itself.

Despite the difference, you can optimise the same page to support both goals because effective AEO starts with strong SEO. High rankings make the content eligible, and then a clear structure and early answers help it win the direct-answer slot.

GEO vs SEO

SEO and GEO can also work together, but they serve different purposes. Unlike SEO, which improves your visibility in search engines like Google, GEO aims to get your brand mentioned or cited in the answer an AI system writes.

As a result, measurement shifts. While SEO watches rankings and clicks, GEO measures citation rate and brand mentions across tools such as ChatGPT, Perplexity, and Gemini.

Differences aside, SEO supports GEO because AI tools need your page to be crawlable and authoritative to discover it easily. Once that foundation is in place, add the signals generative systems favour, including original facts, consistent brand information, and mentions on trusted third-party sites.

AEO vs GEO: What’s the Difference?

People often use AEO and GEO interchangeably since they both involve AI-driven search and information retrieval. However, they are not the same.

AEO: You want Google/answer systems to quote your content as direct answers.

GEO: You want AI systems to recognise your brand and content as a useful source when generating an answer.

Suppose you publish an article explaining GEO vs SEO. If someone searches,

“What’s the difference between GEO and SEO?"

• An AEO success would be Google displaying your definition as a featured snippet or another direct response with a link back to your website.
• A GEO win would be ChatGPT using information from your article to generate its own response and cite your brand as a source.

The biggest difference is how the answer is created. With AEO, the system usually extracts words directly.

With GEO, the AI combines information from several trusted sources to generate a new response. In other words, your content influences the answer, but it may not be quoted word for word. Additionally, some generative tools may not provide a link or any attribution.

Due to these differences, AEO and GEO measure success differently.

A few AEO success metrics include:

• Featured snippet visibility: Appearing in Google’s direct answer boxes.
• Voice search answers: Being selected by voice assistants as answers to user queries.
• Position zero visibility: Ranking above traditional search results as the first answer.

GEO success can be measured with:

• AI Brand mentions: How often AI systems mention your brand in responses.
• AI Citations: Whether your brand is linked or referenced as a source.
• Share of voice in AI responses: How frequently your brand appears compared to competitors.

SEO vs AEO vs GEO vs LLM

SEO, AEO, and GEO are optimisation approaches that help brands improve visibility across different search experiences. A Large Language Model (LLM), however, is the technology that powers many generative AI tools such as Claude, Gemini, and ChatGPT.

But as AI search evolves, marketers have also started using terms such as LLMO (Large Language Model Optimisation) and LLM SEO.

These terms generally describe the process of helping AI models discover, understand, and accurately represent your brand. Although definitions vary across the industry, the primary goal is similar.

A quick overview of each approach.

What Should Brands Optimise for Now?

Brands shouldn’t choose between SEO, AEO, and GEO. They should use all three together.

SEO builds the foundation by making your content discoverable. AEO delivers fast visibility in answer formats users see first, while GEO builds long-term influence in the tools users increasingly use for research.

Together, these strategies help your brand stay visible wherever people search.

How To Build an Integrated SEO, AEO, and GEO Strategy

Today, brands need to optimise for Google Search, AI overviews, answer engine surfaces, and AI assistants. The good news is that you don’t need three completely different strategies.

A solid SEO strategy naturally supports AEO and GEO when your content is helpful, well-structured, and authoritative.

Here’s how to build a strategy that works across all three.

1. Build a Strong SEO Foundation

Before optimising for answer engines or generative AI platforms, brands must ensure their website is easy for search engines to crawl, understand, and rank.

As stated earlier,

• Create helpful content that matches search intent.
• Improve website speed and mobile usability.
• Organise your website with a clear structure.
• Use internal links to connect related content.
• Fix technical issues that prevent search engines from accessing important pages.

These same signals also support AEO and GEO because AI systems need reliable and accessible information before they can extract or reference it.

2. Create Content That Answers User Questions

This step is important because modern search is becoming more conversational. Instead of typing short phrases like “best CRM tool", users often ask complete questions. Your content should answer those questions directly.

For example, if your article targets “email marketing software", you can include headings like

• What is the best email marketing software for small businesses?
• How do I choose email marketing software?
• Is free email marketing software worth it?

You should also give attention to building authority in your niche. An effective strategy is to create a content cluster with a pillar page, supporting guides, comparisons, FAQs, tutorials, use cases, and any other relevant angle for full coverage.

Connect these articles using internal links so search engines and AI systems can understand the relationship between them.

Also, prioritise clarity when writing.

• Answer questions near the top of each section.
• Use question-based headings.
• Focus on everyday conversational questions people type or speak when they want direct answers.
• Use lists and tables where they improve readability.

3. Use Structured Data

Structured data helps search engines understand what your content is about. It works by adding standardised code, called schema markup, to your pages. You might mark a page as an article, a product, a how-to guide, or a set of FAQs.

This doesn’t guarantee higher rankings, but it makes it easier for search engines to interpret your content and display rich search features.

So review your structured data regularly to ensure it matches the visible content on the page. Tools like Google’s Rich Results Test can help show if your current markup works as intended.

4. Strengthen Your Brand Authority for AI Search

AI systems need signals that show a source is reliable. A brand that consistently demonstrates expertise is more likely to be recognised as a useful source.

One of the best ways to build that trust is to create content that goes beyond basic information. Include original research, industry insights, expert commentary, case studies, detailed guides, and firsthand experience.

The more unique value your content provides, the more reasons search engines and AI systems have to recognise your brand as an authority.

5. Earn Third-Party Mentions

Your brand’s credibility doesn’t only come from what you say about yourself. Mentions from trusted sources can strengthen how search engines and AI systems understand your authority.

Other than creating rich content that relevant sites would naturally want to reference, here are a few more ways to earn third-party mentions:

• Guest articles: Write opinion pieces or contribute expert insights to reputable industry publications.
• Digital PR: Share original research, surveys, or company news with journalists and media outlets to earn additional coverage.
• Podcast and webinar appearances: Participate in industry discussions to showcase your expertise and increase brand visibility.
• Industry events: Speak at conferences where your insights may be quoted by attendees or the media.
• Strategic partnerships: Collaborate with complementary businesses, organisations, or influencers on research, events, or content that earns mutual exposure.

6. Keep Your Brand Messaging Consistent

Consistent brand messaging ensures every system—Google, AI models, and even users—understands who you are, what you do, and what you’re an authority on.

Search engines and AI systems build an understanding of your brand by gathering information from multiple sources. If your website says one thing while your social profiles or business listings say another, they’ll have a harder time understanding your brand.

To maintain consistency:

• Create a style guide to govern branding across teams.
• Update outdated business information whenever your offerings change.
• Ensure your business name, products and services, company description, contact information, and positioning remain consistent across your website, social media, and business directories.
• Frequently audit your branding across platforms.

7. Monitor Performance and Update Content

Search behaviour changes constantly, so optimisation shouldn’t end after you publish content. Regular monitoring helps brands understand what works and where they need improvements.

Also review existing content regularly. Update outdated statistics, improve unclear sections, add missing answers, and strengthen information that supports your expertise.

How To Measure Success with SEO, AEO, and GEO

Measuring success looks different for SEO vs AEO vs GEO because each focuses on a different type of search visibility.

How to Track SEO

SEO has well-established metrics and tools for measuring performance. The goal is to understand how visible your brand is in traditional search results and whether that visibility drives meaningful traffic and conversions.

Some of the important SEO metrics to track include

• Keyword Rankings: This monitors where your pages rank for target keywords on search engines.
• Organic Traffic: Measures the number of visitors arriving at your website through unpaid search results.
• Click-Through Rate (CTR): CTR tracks the percentage of users who click your page after seeing it in search results.
• Backlinks: Track the number and quality of websites linking to your content.
• Coverage Errors: Shows indexing issues, crawl errors, and pages that search engines cannot access.
• Page Speed: Google Search Console reports Core Web Vitals, a set of metrics that measure the user experience of your website. The three Core Web Vitals are outlined below.
  • Largest Contentful Paint (LCP) measures how quickly the largest visible element on a page loads. A good LCP is 2.5 seconds or less.
  • Interaction to Next Paint (INP) tracks how long a page takes to respond to user interactions such as clicks or taps. Anything under 200 milliseconds is a good INP.
  • Cumulative Layout Shift (CLS) measures a page's visual stability by tracking unexpected layout shifts during loading. Aim for a 0.1 CLS score or lower.

Here’s an overview of the most commonly used SEO tools.

How to Track AEO

With AEO, your content can appear as the direct answer to search queries, appear in supporting answer features, or not appear at all. This is what you need to track.

For traditional answer features such as featured snippets and PAA, you can use many of the same SEO tools that track search visibility.

However, measuring AEO is more complex with AI-powered experiences. See a few tools you can use below.

How to Track GEO

With traditional SEO, when a user searches a keyword:

• Google shows a results page
• Your ranking position can be tracked
• SEO tools can record that position over time.

AI outputs are different. The answers can vary if:

• The AI interprets the prompt slightly differently
• New information becomes available
• The model retrieves different sources
• User context changes
• The AI system updates

With each response, your brand can either be mentioned, cited, or not referenced at all. So when tracking GEO, what you’re essentially checking is visibility.

Here’s how to check:

1. Start by creating a list of high-intent questions or prompts your audience is likely to ask. For example, a cybersecurity company might choose questions such as, “What are the best cybersecurity companies for small businesses?" “What cybersecurity tools should small businesses use?”
2. Test those questions in AI platforms.
3. For each prompt, check if the AI:

• Mentions your brand
• Recommends your business
• Links to your website
• Cites your content as a source

Repeat the same prompts regularly and record the results in a spreadsheet to spot trends over time. Several platforms can automate this process.
