At a glance
SEO: Make useful pages discoverable, crawlable, indexable and relevant to searches. Common work includes information architecture, technical fixes, internal links and content refinement.
AEO: Organize verified facts so a reader or answer system can find a direct answer and supporting context. Typical work includes question research, concise explanations and clear attribution.
GEO: Examine and improve the consistency of information about an organization across sources potentially used by generative systems. Work may include entity accuracy, authoritative references and careful observation of AI answers.
These terms are used differently across the industry. They describe useful workstreams rather than official Google ranking categories.
Example: a software agency
Suppose a company offers workflow automation. An SEO task might fix a service page that is not linked anywhere and returns an incorrect canonical URL.
An AEO task might add an accurate explanation of when to choose a visual workflow builder versus custom Node.js code, including trade-offs and examples.
A GEO task might verify that the company name, actual services and documented work are consistent on its own website and on relevant independently maintained profiles. None of these actions makes a platform obliged to feature the agency.
How to choose your first priority
If important pages cannot be indexed, address SEO fundamentals first. If pages attract visitors but fail to answer buying questions, improve explanation and information architecture. If answers about your organization contain errors, audit the source facts and independent references before trying to increase mentions.
These are sequencing decisions, not three separate subscription packages every business automatically needs.
Measurement that does not mislead
For SEO, use search impressions, clicks, crawl diagnostics, index coverage and conversions, while accounting for seasonality and query intent.
For AEO, assess whether pages answer selected questions well, whether those pages are accessible and whether cited links appear for carefully documented prompts. For GEO, check factual consistency across external and internal sources and record observed AI answers with platform, date and language.
A claim such as “ranked number one in ChatGPT” is usually underspecified. Unlike a fixed search position, AI outputs may change across runs.
What Google actually requires
Google says AI Overviews and AI Mode rely on the usual Search technical requirements, and it does not prescribe extra technical optimizations specifically for those features. Being indexed and eligible for a snippet is a prerequisite for potential supporting links, not a guarantee.
Compare the differences against the underlying guidance rather than treating AEO/GEO labels as new Google standards.
SEO vs AEO vs GEO comparison table
| Focus | SEO | AEO | GEO |
|---|---|---|---|
| Primary question | Can this page be found and understood? | Does it answer a specific question well? | Is the brand represented accurately across sources? |
| Typical work | Canonical, crawl, internal links, search intent | Direct answers, explanation, clear evidence | Entity consistency, citations, source verification |
| Practical example | Fix a noindex on a service page | Explain when n8n is preferable to custom code | Correct outdated public descriptions of the service |
| Observable measures | Index coverage, impressions, clicks, enquiries | Answer quality, recorded citations, useful actions | Factual accuracy, observed mentions and linked sources |
| Guaranteed result? | No ranking guarantee | No answer inclusion guarantee | No generative citation guarantee |
These are practical industry working definitions, not three separate Google ranking programs. Start where the website has measurable gaps.

Questions readers ask
Should I invest in SEO or AEO first?
Start with crawlability, indexability and useful content. If those work, prioritize questions and evidence that matter to your audience. Most AEO tasks depend on those SEO foundations.
Can GEO guarantee a brand mention in AI tools?
No. Generative systems select and summarize information independently, and outputs can vary across sessions, products and locations.
