SEO vs AEO vs GEO vs Prompt Optimisation: What's the Difference in 2026?
If you've spent any time researching digital marketing lately, you've probably noticed a wave of new acronyms popping up alongside the familiar term "SEO." AEO, GEO, and prompt optimisation are now part of the conversation — and understanding how they differ (and how they work together) is essential if you want your business to stay visible online, whether that's on Google, in an AI chatbot answer, or in a voice search result.
Here's a clear breakdown of each term, what it means for your business, and why working with a specialist matters more than ever.
What is SEO (Search Engine Optimisation)?
SEO is the foundation of digital visibility. It's the practice of optimising your website's content, structure, and technical performance so that search engines like Google rank you higher for relevant searches. This includes keyword research, on-page optimisation, backlink building, site speed, and mobile usability.
If you're looking for reliable search engine optimisation services or a trusted search engine optimisation agency, SEO is still the starting point — it's what gets your business found by people actively searching for what you offer.
What is AEO (Answer Engine Optimisation)?
AEO focuses on optimising content so it gets pulled directly into "answer" formats — think Google's featured snippets, People Also Ask boxes, and voice assistant replies (Siri, Alexa, Google Assistant). Instead of just ranking on a results page, the goal with AEO is to become the answer itself.
This means structuring content clearly with concise, direct answers to common questions, using FAQ schema, and writing in a way that's easy for algorithms to lift and present as a standalone answer.
What is GEO (Generative Engine Optimisation)?
GEO is the newest — and fastest-growing — piece of the puzzle. It's the practice of optimising content so it gets referenced or cited by AI-generated answers from tools like ChatGPT, Google AI Overviews, and Perplexity. Instead of ranking in a list of blue links, your brand is trying to be the source an AI model pulls from when generating a response.
GEO relies on authoritative, well-structured, fact-based content, strong topical relevance, and clear entity signals (things like consistent business information, structured data, and credible citations) that generative engines trust enough to reference.
What is Prompt Optimisation?
Prompt optimisation is about how your content and brand information are structured to perform well when users ask AI tools direct questions or "prompts." Since more people are now asking AI assistants things like "who's the best e-commerce web developer near me" instead of typing a traditional search, businesses need content that's phrased and formatted in a way AI systems can easily understand, interpret, and recommend.
This is closely tied to GEO but focuses more specifically on how your business responds to natural, conversational language queries rather than traditional keyword-based ones.
