The aim is to ensure that content is accurately cited and retrieved in AI summaries rather than simply being clicked on via traditional links.

For example,

What is the difference between AISO and AEO?

Both AEO (Answer Engine Optimisation) and AISO (AI Search Optimisation) are advanced approaches that extend beyond traditional SEO.

However, they serve distinct purposes in the evolving search landscape.

AEO is helpful for:

AEO focuses on making content the direct answer to user queries. The aim is to achieve visibility in ‘Position Zero’, featured snippets, and voice assistants such as Siri and Alexa, as well as AI-generated summaries.

To this end, AEO uses conversational language, FAQ-style structures, and concise, bulleted responses to provide immediate clarity.

AEO is best suited to short-tail queries, voice search, and situations where users expect quick, direct answers.

AISO as compared to AEO

AISO is designed for AI-native search engines and conversational platforms, such as ChatGPT, Perplexity, and Gemini.

Its goal is to ensure that content is cited as a trusted source or becomes the authoritative answer within generative AI responses, not just to increase visibility.

AISO strategies emphasise topical authority, entity-based SEO, structured data, and building brand trust, enabling large language models to recognise and rely on the content.

Unlike AEO, which focuses on brevity, AISO thrives on deep, comprehensive, and authoritative content that AI systems can summarise with confidence.

Essentially, AEO involves optimising for immediate answers in human-facing search experiences, whereas AISO involves positioning content as a reliable foundation for AI-driven knowledge systems.

Together, they represent a shift in focus from ranking documents to providing reliable answers in both traditional and AI-powered search environments.

Is AISO better than SEO?

Let’s be clear: AISO isn’t replacing SEO, it’s adapting it.

AI itself is learning.

Businesses that use AISO to enhance their marketing strategies will have an advantage in terms of search visibility and audience engagement.

In simple terms, SEO aims to generate clicks, whereas AISO aims to ensure inclusion and establish trust within AI-generated answers like Google AI overviews, ChatGPT, and more.

AISO requires a deeper level of expertise, authority, and the creation of structured, scannable content.

Here is the free AI search checklist to help you boost your AI rankings and search visibility on the AISO Blog.

How they work together (the new AI SEO)

SEO is the foundation. High-quality, SEO-optimised content remains essential as AI draws on it.

Adaptation (AEO/GEO):

Answer Engine Optimisation (AEO): Optimising for AI answer engines to extract answers.

Generative Engine Optimisation (GEO): Making content easily understandable and quotable by generative AI.

Some helpful tips are:

1. Structured writing: Use clear headings, concise paragraphs and Q&A formats.
2. Schema markup: This helps AI to understand the context of the content.
3. Authority: Build web-wide credibility as AI cites sources.
4. Citation tracking: Monitor how often your content is cited in AI-generated answers. You can use PromptWatch AI for this.

AI search doesn’t replace SEO; it changes the search marketing game.

The future lies in a blended marketing strategy of using strong SEO to establish visibility and authority, while also adopting AEO/GEO to secure direct placement in AI-generated answers.

This approach captures both top-of-funnel awareness and high-intent users.
