As we see more Google updates and AI continues to expand into search, the more acronyms seem to appear in the SEO world. So, let’s have a look into what they mean, what’s the difference between them, and how to optimise for each.
What is SEO?
Let’s start from the beginning with SEO. The original acronym.
SEO stands for Search Engine Optimisation, meaning to optimise a website and improve its visibility on search engine results pages (SERPs), such as Google.
In simple terms, it’s the practice of getting a website to rank at the top of a page when a user enters a relevant search term. As SEO focuses on organic search visibility, unpaid unlike PPC, your website would typically appear under sponsored results.
SEO involves conducting keyword research and creating useful content which targets relevant keywords. SEO also involves organising your site structure, adding internal links throughout the site, and correctly layering headings.
What is AEO?
AEO stands for Answer Engine Optimisation. While SEO focuses on improving a website’s visibility in search results, AEO focuses on providing answers to the questions users are searching for.
The rise of answer-focused search shows how user behaviour is changing. Users don’t always want to browse through several websites to find the information they need. Instead, search engines and AI platforms can provide a direct answer.
AEO involves creating content that clearly and concisely answers common questions. This includes using question-based headings, providing straightforward answers and structuring information in a way that makes it easy for search engines to understand.
For example, a page targeting the search “what is PPC?” could provide a clear definition near the beginning of the page, followed by more detailed information. This gives search engines a straightforward answer that they can understand and use when responding to a user’s query.
What is GEO?
GEO stands for Generative Engine Optimisation. It refers to optimising content so that it can be found, understood and potentially referenced by generative AI search tools.
Traditional search engines return a list of links in response to a query. Generative search tools, meanwhile, can use information from multiple sources to create a response for the user.
GEO therefore, focuses on making content useful and easy for AI systems to interpret. This includes providing accurate, well-structured and relevant information, using clear language and demonstrating expertise on a subject.
Unlike traditional SEO, where the primary goal is to achieve a higher organic position in search results, GEO focuses on how content may be shown within AI-generated answers.
What is the difference between AEO and GEO?
AEO and GEO have some overlap, but they focus on slightly different aspects of search.
AEO is primarily concerned with answering questions clearly and helping content to provide a useful response to common search queries. GEO is focused on visibility within generative AI search, where an AI system may use information from several sources to produce its answer.
For example, an FAQ answering “How long does PPC take to implement?” is an example of content that can support AEO. The same content could also contribute to GEO if it is accurate, well structured and useful enough to be considered as a source by an AI-powered search system.
The two approaches are therefore not completely separate. Good AEO and GEO strategies can both involve creating helpful, authoritative content that directly addresses what users want to know.
What is AIO?
AIO refers to AI Overviews, which can often be seen at the top of SERPs. AI Overviews are Google’s AI-generated summaries that often appear at the top of search results. They provide users with information about their query without requiring them to visit multiple websites to get an answer.
AI Overviews may also include links to webpages that support or provide further information on the answer. This creates another way for websites to gain visibility in search as rather than only aiming to appear as a traditional organic result, you can create content that is useful and clear enough to potentially be referenced within an AI Overview.
This is where AIO overlaps with SEO and GEO. Traditional SEO helps search engines to discover and understand a website, while GEO considers how content can be surfaced in generative search experiences. AIO specifically relates to Google’s AI Overview feature within its search results.
What is SXO?
SXO is one of the newer terms, but it’s based on a lot of the principles and mechanics that have been a part of digital marketing for years. SXO stands for Search Experience Optimisation and it’s what happens when good SEO, UX design, and a little bit of marketing know-how come together.
Technical SEO is a major component of SXO. Good site architecture, fast loading speeds and easy-to-use navigation are all elements that help a site to rank well. Mobile speed and usability are especially crucial to a site’s ranking.
UX design is the next pillar of SXO. A useful website should make it as easy as possible for visitors to find what they came to the page for, navigate where they want to go and complete any actions they want to take, whether that’s making a purchase or filling out a form. Everything from button placement and page layout to accessibility can affect the user experience, and Google knows how important this is.
The final pillar to SXO is the overall digital marketing strategy and user journey. Are visitors reading to the end of the page? Are they viewing products and adding them to a cart? Are they becoming a lead by filling out a form? The digital marketing manager might know these metrics but does the SEO writer know them too? Are the UX designers and developers creating pages that improve Google ranking and help visitors convert?
There’s No Guaranteed Formula for Search Visibility
There are plenty of ways to optimise your content for SEO, AEO, GEO, AIO, and SXO but none of them guarantee that your website will appear in a particular position or place.
Search engines and AI platforms use complex, constantly changing algorithms to decide which information to show users. While structuring content clearly, answering questions directly and demonstrating expertise can all help, they are not shortcuts to visibility.
Ultimately, all approaches come back to the same foundation: good SEO. Creating useful, relevant and trustworthy content, making sure your website is technically sound and understanding what your audience is searching for remain at the heart of search visibility.
Even Google has stated that appearing in AI search is built on the foundations of good SEO practices.
