Ranking on Google has been the game for twenty odd years. You hired an SEO person, targeted keywords, built backlinks, and scrapped for a spot on page one. That playbook still matters. But something fundamental has shifted underneath it.
Millions of people now skip Google entirely. They open ChatGPT, Perplexity, Gemini, or Claude and just ask what they need. "Best accountant in Sandton." "Affordable web designer in Cape Town." "Reliable courier service in Durban." These AI assistants don't return a list of ten links. They give a direct answer, naming specific businesses. The question isn't just "How do I rank?" anymore. It's "How do I become the business that AI recommends?"
That's AI Engine Optimisation (AEO). If you're a South African business that moves on this early, you'll have a lead that competitors will struggle to close.
AEO in Plain Terms
AEO is the practice of structuring your website, content, and online presence so that AI powered search engines and assistants cite your business when answering user queries. Traditional SEO is about ranking for keywords and blue links. AEO is about becoming a trusted, authoritative source that AI models pull from when generating answers.
Picture it this way. Someone in Durban asks ChatGPT "best plumber in Durban." There's no list of ten results. There's a direct recommendation, maybe two or three businesses named. AEO is what gets your business into that answer.
Why SA Businesses Should Pay Attention Now
South Africa's digital landscape is moving fast. We have over 43 million internet users, smartphone adoption keeps climbing, and more South Africans interact with AI tools every month.
ChatGPT alone has over 200 million weekly active users globally, and plenty of them use it for local recommendations and product research. Most local businesses haven't even heard the term AEO. If you optimise now, you'll dominate AI generated recommendations while competitors are still trying to figure out what happened.
There's a cost argument too. Paid clicks run R50 to R200 each. Being cited by AI costs nothing per click. Once you're positioned, you earn visibility without ongoing ad spend. And research shows people treat AI generated suggestions similarly to a friend's recommendation, so getting named by ChatGPT carries real weight.
How Do AI Engines Decide What to Recommend?
AI models aren't Google's web crawlers. They're trained on massive datasets and use real time retrieval (Perplexity and ChatGPT with browsing, for instance) to surface authoritative, well structured information. Several factors determine whether your business gets cited.
E E A T Signals
Experience, Expertise, Authoritativeness, Trustworthiness. Google introduced this as a quality guideline, and AI engines have adopted similar principles. Your content needs to show genuine expertise. A Johannesburg accounting firm needs detailed guides on SA tax law, not generic articles recycled from American websites. AI can tell the difference.
Structured Data and Schema Markup
AI engines eat structured data for breakfast. Implementing schema.org markup (LocalBusiness schema, FAQ schema, Review schema) helps AI understand exactly what your business does, where you operate, and what customers say about you. Most SA businesses have none of this in place.
One of the easiest wins? Adding an FAQ knowledge base to your website. Well structured FAQs with proper schema markup feed AI engines the exact question and answer pairs they're scanning for.
Authoritative, Comprehensive Content
AI models favour content that covers a topic thoroughly. A 300 word blog post won't get you anywhere. You need in depth, well researched articles that answer real questions your customers are asking. Having a blog content section on your site isn't a nice to have anymore. It's infrastructure for AEO.
Consistent Online Presence
Your business name, address, phone number, and services must be consistent everywhere. Your website, Google Business Profile, directories, social media. AI models cross reference multiple sources. Inconsistencies erode trust fast.
Practical AEO Steps You Can Take This Week
Run your site through Google's Rich Results Test. Check whether you have proper schema markup. At minimum, you want LocalBusiness, FAQ, and Service schema. Running an e commerce store? Add Product and Review schema too.
Then start creating question based content. Find out what your customers actually ask. Tools like AnswerThePublic, Google's "People Also Ask," and ChatGPT itself can surface these queries. Create content that directly and thoroughly answers each one. For a deeper look at content strategy, read our guide on SEO for South African businesses.
Don't write one article about your industry. Write twenty. AI engines recognise topical clusters. A Cape Town estate agency that publishes comprehensive guides on every aspect of property buying in the Western Cape will be cited far more often than one with a single "About Us" page and a three paragraph blog post from 2022.
Earn Citations and Mentions
AI models weigh how often your brand gets mentioned across the web. Get featured in SA publications like BusinessTech, MyBroadband, and industry specific directories. Each mention reinforces your authority in the model's eyes.
People talk to AI assistants the way they'd talk to a friend. "What's the best web design agency in Pretoria for a small business?" Your content should match this conversational, long tail style rather than stilted keyword phrases nobody actually says out loud.
AEO and SEO Work Together
AEO doesn't replace SEO. It builds on top of it. The fundamentals (fast site speed, mobile optimisation, quality backlinks, strong content) all contribute to AEO performance too. Think of AEO as the next layer on a solid SEO foundation.
At Horizon Labs, we build websites with both SEO and AEO in mind from the start, incorporating structured data, authoritative content architecture, and the technical foundations AI engines need to discover and cite your business.
The Window Won't Stay Open Forever
Right now, most South African businesses are completely invisible to AI search engines. Their websites lack structured data, their content is thin, and they have no AEO strategy whatsoever. That means the barrier to entry is low and the opportunity is massive.
Give it three to five years and AEO will be as competitive as SEO is today. The businesses that start now, building authoritative content, implementing proper schema, establishing E E A T signals, will be the ones AI engines recommend by default. Your competitors will figure this out eventually. The question is whether you'll already be the recommended business by the time they do.
