Search engine optimisation has come a long way—and it’s no longer just about ranking on Google. As artificial intelligence, user experience, and search intent evolve, so too do the strategies we need to stay competitive online.
If you’ve come across terms like SEO, AIO, GEO, AEO, and SXO and felt overwhelmed, you’re not alone. These acronyms might sound technical, but understanding them is easier than you think—and they’re all crucial in shaping the future of digital visibility.
Let’s break each one down in a friendly, easy-to-digest way.
1. SEO – Search Engine Optimisation
The foundation of visibility on search engines.
What It Means
SEO is the classic form of optimising your content so that it ranks higher on search engines like Google.
How It Works
- Targeting relevant keywords your audience searches for
- Building backlinks from reputable sources
- Improving on-page content (headings, images, internal links)
- Fixing technical SEO issues (site speed, mobile-friendliness, crawling, etc.)
Ask Yourself
“Will this help me rank higher on Google?”
Example
A SaaS company gets to the #1 spot for “CRM for freelancers” by optimising its landing page with target keywords and getting backlinks from niche blogs.
2. AIO – AI Optimisation
Helping AI learn more about your content.
What It Means
AI Optimisation is about structuring your content so it can be understood, indexed, and even learned from by AI models.
How It Works
- Including content in structured, readable formats
- Ensuring your content appears in credible sources (like forums, documentation, and knowledge bases)
- Using consistent, factual references to strengthen authority
Ask Yourself
“Will this help the model learn about me?”
Example
A software library becomes part of an AI’s knowledge base because its documentation is well-structured, factual, and cited in places like GitHub and Wikidata.
Why It Matters
AI now powers many parts of search engines and content delivery. By optimising for AI, your brand is more likely to be referenced by AI models like ChatGPT, Google Gemini, and others.
2. GEO – Generative Engine Optimisation
Optimising for AI-generated answers, not just links.
What It Means
GEO focuses on creating content that appears in generative search results—like ChatGPT answers, Google’s AI Overviews, or Bing Copilot summaries.
How It Works
- Writing factual, clear content
- Structuring content in a format ideal for summarisation
- Using schema markup like FAQ or article tags to help AI understand context
Ask Yourself
“Will this help the model recommend me?”
Example
A travel blog gets featured in a ChatGPT-generated list of “Best Cities in Europe for Digital Nomads” thanks to its clean formatting and trustworthy information.
Why It Matters
As more people rely on AI-generated answers, being cited in those responses becomes just as valuable as traditional search engine rankings.
4. AEO – Answer Engine Optimisation
Giving clear, concise answers to real questions.
What It Means
AEO is all about positioning your content to appear as featured answers or AI Overview highlights by addressing searcher questions directly.
How It Works
- Providing direct, concise answers to specific questions
- Using FAQ sections, How-To schemas, and structured formats
- Aiming for zero-click results, where users get the answer directly from the search engine
Ask Yourself
“Will this be the answer Google highlights?”
Example
A finance blog answers “What is capital gains tax?” in the opening paragraph using plain language, and that snippet gets picked up in Google’s AI Overview.
Why It Matters
More people are getting answers without clicking into websites. AEO ensures your content is still seen and credited, even in these fast, no-click formats.

5. SXO – Search Experience Optimisation
Turning traffic into meaningful action.
What It Means
SXO shifts the focus from just “getting clicks” to delivering a great experience that leads to action—whether it’s a sign-up, purchase, or longer time spent on-site.
How It Works
- Building fast, mobile-friendly pages
- Applying CRO (Conversion Rate Optimisation) with clear CTAs
- Matching search intent with easy-to-read, scannable content
Ask Yourself
“Will this turn traffic into action?”
Example
An e-commerce site loads fast, clearly satisfies user intent, and converts three times more than slower competitors with confusing navigation.
Why It Matters
High rankings mean nothing if users leave immediately. SXO ensures your content converts visitors into customers or leads.
Putting It All Together
Each of these optimisation methods plays a unique role in today’s—and tomorrow’s—digital landscape:
| Term | Focus Area | Purpose |
| SEO | Classic search engines | Rank higher on Google |
