What is GEO (Generative Engine Optimization)?
GEO is the process of optimising content to get cited in AI-generated search results. Instead of ranking in traditional Google results, you optimise to be selected as a source by ChatGPT, Google Gemini, Perplexity, Claude, and other AI engines.
This isn't replacing traditional SEO—it's supplementing it. As more users rely on AI to answer questions, your visibility depends on being selected as a credible source for those AI systems.
How AI Engines Select Sources
Google AI Overviews
Google's AI selects sources based on:
- Topic authority and topical relevance
- E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness)
- Content freshness (recently updated content ranks higher)
- Clear content structure (H2s, lists, tables are easier for AI to parse)
- Current Google ranking (top 10 rankings increase citation probability)
ChatGPT & Perplexity
These models are trained on web data and select sources based on:
- Content relevance to the user query
- Domain authority (established brands are cited more often)
- Content comprehensiveness (longer, more detailed content gets cited)
- Recency (training data cutoffs mean older content is less visible)
Key insight: Being ranked on Google first significantly increases your chance of being selected as an AI source. Most AI models are trained on Google-indexed content.
South African GEO Case Study
A Johannesburg-based B2B SaaS company wanted to rank for "enterprise software for South African logistics." They:
- Created a 4,000-word pillar page optimised for Google Search (achieved #3 ranking in 6 months)
- Added comprehensive FAQ section with 15+ questions
- Implemented FAQPage and BlogPosting schema
- Used clear H2/H3 structure and tables comparing competitors
Result: Within 2 months of Google ranking, the page began appearing in Google AI Overviews and was cited by Perplexity for logistics software queries.

Questions Google AI Overviews Favor
AI engines prefer answering:
- Comparison questions: "A vs B" (AI synthesises multiple sources)
- How-to questions: Step-by-step content is ideal
- List questions: "Top 10 X" or "Best practices for Y"
- Definitional: "What is GEO?"
- Numerical: "How much does X cost?" (with pricing tables)
AI vs. Google: Which Should You Optimise For?
Optimise for Google first. Here's why:
- Google AI Overviews still send traffic to sources (unlike ChatGPT)
- Google ranking signals translate to AI citations
- Good structure for Google = good structure for AI
- Most AI models are trained on Google-indexed content
Don't abandon traditional SEO for GEO. They're complementary.
