A new type of search is reshaping how customers find businesses. Instead of typing “best digital marketing agency Sydney” into Google and scrolling through results, people are asking AI assistants: “What’s the best digital marketing agency in Sydney?” — and getting direct, cited answers.

Generative Engine Optimisation (GEO) is the discipline of making your business visible in AI-generated search responses. When ChatGPT, Google Gemini, or Perplexity answers a question about your industry, GEO determines whether your business gets cited — or whether a competitor does.

This is the most important new marketing skill of 2026. And almost no Australian businesses are doing it yet.

What Is GEO and Why Does It Matter?

Traditional SEO: Rank in Google → Get clicks → Drive traffic → Convert sales.

GEO: Be cited by AI → Appear in AI answers → Get recommended to searchers who trust AI → Drive brand awareness and traffic.

The scale of AI search in 2026:

• ChatGPT has over 200 million weekly users
• Google’s AI Overviews appear in most US searches (Australian rollout underway)
• Perplexity has become a preferred research tool for professionals and students
• Microsoft Copilot integrates AI search across the entire Windows ecosystem

When someone asks an AI “What software should I use for my marketing agency?” — the AI’s answer often drives a direct purchase decision. If your product or service is cited, you get the sale. If a competitor is cited, they get it.

For Australian SMBs, GEO is opportunity. Competition in AI citations is minimal right now. Early movers will dominate AI-generated responses for years.

Section 1: How AI Search Engines Choose What to Cite

Understanding how AI search engines select sources is the foundation of GEO.

Large Language Models (LLMs) like ChatGPT and Gemini are trained on massive datasets from the internet. When answering a question, they generate responses based on patterns learned during training — and cite sources that appear authoritative and relevant.

Key factors that determine citation likelihood:

1. Domain authority — High-DA websites with strong backlink profiles are cited more often
2. Content freshness — Updated, current content is preferred over outdated pages
3. Topical relevance — Content that directly and comprehensively answers the question
4. Structured data — Schema markup helps AI parse and understand your content
5. Brand mentions — Businesses frequently mentioned across multiple sources are cited more
6. Review authority — High review scores and volume signal trustworthiness
7. Wikipedia/data sources — Having a Wikipedia page or appearing in structured databases significantly boosts citation frequency

Section 2: GEO Strategy — Getting Cited by ChatGPT

ChatGPT (and GPT-4o) cites sources from its training data and, increasingly, from Bing search results (via Microsoft’s integration). To be cited by ChatGPT:

1. Rank in Bing — Yes, Bing matters now. ChatGPT’s browsing uses Bing. Optimise your website for Bing as well as Google.
2. Create original research — ChatGPT prioritises citing original data and research. Publish original case studies, industry surveys, and research reports with real data.
3. Get quoted in media — News articles and industry publications that quote you directly increase your citation likelihood. Build PR relationships and contribute to industry publications.
4. Become part of the knowledge graph — Create structured data, maintain consistent NAP across directories, and ensure your business appears accurately across authoritative databases.
5. Answer questions comprehensively — Create FAQ content that answers specific questions your target audience asks AI. If your content provides the best answer to a common question, AI will cite it.

Section 3: GEO Strategy — Getting Cited by Google Gemini

Google Gemini operates differently from ChatGPT. It integrates with Google Search, pulling from Google’s index — which means traditional SEO is still relevant, but with important additions.

To be cited by Gemini:

1. Strong Google rankings — Gemini citations overlap heavily with top Google results. Rank in Google, get cited in Gemini.
2. E-E-A-T optimisation — Gemini heavily weights E-E-A-T signals. Author credentials, about pages, professional certifications, and Google Business Profile all feed Gemini’s authority assessment.
3. Google Business Profile completeness — Gemini cites GBP information for local queries. A fully optimised, regularly updated GBP increases local Gemini citation frequency.
4. Structured data richness — The more schema markup you implement, the better Gemini understands your content and the more likely it is to cite you accurately.
5. YouTube presence — Google’s AI Overviews increasingly pull from YouTube videos. Create educational YouTube content addressing your industry’s key questions.

Section 4: GEO Strategy — Getting Cited by Perplexity

Perplexity is used primarily by researchers, professionals, and tech-savvy users. It’s a high-value citation source because users trust it deeply and act on its recommendations.

To be cited by Perplexity:

1. High-authority backlinks — Perplexity prioritises sources with strong domain authority and credible backlink profiles. Focus on earning links from industry publications, government websites, and authoritative directories.
2. Fresh, updated content — Perplexity weights recency. Regularly update your key pages with fresh data and current information.
3. Comprehensive, structured content — Perplexity rewards content that directly answers questions in structured formats (headers, bullet points, clear sections). It’s easier for the AI to parse and cite.
4. Be referenced by other cited sources — If other highly cited websites mention your business, Perplexity’s citation algorithm learns to associate you with authoritative content.
5. Industry publication presence — Get guest posts, interviews, or mentions in your industry’s leading publications. These publications are already high-authority sources that Perplexity cites regularly.

Section 5: Measuring GEO Performance

GEO measurement is in its infancy, but here’s how to track it:

1. Manual testing — Regularly ask ChatGPT, Gemini, and Perplexity questions about your industry and check if you’re being cited
2. Brand mention tracking — Use tools like Mention or Google Alerts to track when your brand appears across the web
3. Referral traffic analysis — Look for referral traffic from AI-related sources in Google Analytics
4. Direct AI traffic — Some AI platforms pass referral data; check analytics for perplexity.ai, chat.openai.com traffic

Conclusion

GEO is the new frontier of digital marketing. The businesses investing in AI citation strategies today will dominate AI-generated recommendations in 2027 and beyond. Build authority content, earn media coverage, optimise for E-E-A-T, and actively test your AI visibility.
