Core Capabilities

AI SEO & Generative Engine Optimisation (GEO) Services in Australia

We deliver five specialized commercial workstreams engineered to capture high-intent brand recommendations across generative search.

01 / WORKSTREAM

Generative Engine Optimization (GEO)

We structure brand entity profiles, digital PR citations, and authoritative web consensus so conversational language models recommend your business when prospects evaluate your category.

02 / WORKSTREAM

Google AI Overviews & AEO

We re-engineer content hierarchies into declarative summaries, structured comparison tables, and factual data points that Google's Gemini retrieval models extract for answer snapshots.

03 / WORKSTREAM

Machine-Readable Technical SEO

We manage crawler access policies for AI retrieval bots, build comprehensive multi-entity JSON-LD Schema graphs, and deploy machine-readable content endpoints including llms.txt.

04 / WORKSTREAM

Selection Rate Optimization (SRO™)

Using proprietary mathematical rankers, we test and refine passage length, entropy, and information density to maximize the probability that models quote your text once retrieved.

05 / WORKSTREAM

AI Sentiment & Hallucination Mitigation

We systematically probe large language models to identify competitive misattributions, outdated pricing, or hallucinations, executing off-site entity realignments to correct model memory.

STRATEGIC ASSESSMENT

AI Search Vulnerability Audit

A comprehensive 30-day evaluation measuring baseline mention share across Google AI Overviews, ChatGPT, and Perplexity, complete with a prioritized engineering roadmap.

Multi-Model Engine Coverage

Optimising Visibility Across ChatGPT, Google AI Overviews, Perplexity & Gemini

Each generative engine uses distinct retrieval architectures, citation thresholds, and context weights. We engineer specific entity signals for each major platform.

GOOGLE AI OVERVIEWS & GEMINI

Google Search Grounding

Optimizing passage extractability, structured tables, and Schema graph consensus for Google's multimodal Gemini models.

OPENAI CHATGPT & SEARCHGPT

ChatGPT SEO

Structuring authoritative digital PR, verified entity profiles, and high-trust index signals favored by OpenAI retrieval.

PERPLEXITY AI

Perplexity Citation Engine

Engineering real-time fresh citations, domain-specific authority, and web consensus for Perplexity's answer synthesis.

ANTHROPIC CLAUDE

Claude Knowledge Alignment

Aligning long-form technical documentation, machine-readable text files, and high-density domain data for Claude's reasoning models.

Agency Technology Advantage

Proprietary Data Science Infrastructure

Competitors rely on generic manual prompts. DEJAN executes client campaigns using custom computational models and mechanistic interpretability tools.

Client Optimization Engine

Bayesian Content Optimizer

Traditional SEO optimizes for where a page sits on a search results page. Our internal Content Optimizer engine optimizes for whether an AI grounding system chooses to quote your text.

When an AI assistant answers a question, it compares competing sources and selects the most quotable passage. Our agency team uses this custom ranker to iteratively refine target passages until models mathematically prefer your brand over competing sources.

Deployed exclusively on client campaigns by DEJAN search engineers.

The ARC Framework

STAGE 01

Association

Map Connections: We identify what models connect to your brand and what they connect to competitors, mapping the entities that define your category.

STAGE 02

Relevance

Connection Strength: We probe models to turn associations into probabilities, identifying which entities you own outright, which you share, and which belong to competitors.

STAGE 03

Citations

Selection Optimization: We mine the sources AI systems retrieve and rewrite target passages until models prefer your page over competing sources.

The Algorithmic Mechanism

How Generative Engines Decide Who to Recommend

Understanding the technical difference between indexing a document and being selected as a cited authority.

Dimension Traditional Ranking Algorithms Generative Recommendation Engines
Primary Objective Index placement on ten-blue-link results pages Direct brand recommendation and citation in synthesized answers
Evaluation Signals Inverted index keyword matching and PageRank link authority Neural embeddings, entity co-occurrence, and semantic web consensus
Retrieval Architecture Document-level relevance and crawl depth Passage-level extraction, token entropy, and factual density
Target Crawlers Standard web crawlers (Googlebot, Bingbot) AI retrieval crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended)
National Grounding

An Australian Agency, Measured Market by Market

DEJAN has delivered search campaigns from Australia since 2008. The company is registered in Queensland and operates a senior distributed team across Brisbane, Sydney, Melbourne, and Perth.

Market context matters more in AI search than it did in ranked search. The sources a language model retrieves to answer an Australian buyer are not the sources it retrieves for the same inquiry in the United States. A brand can dominate citations in North America while remaining invisible in Australian search results.

Every measurement we report is isolated by market. The question we answer for Australian enterprises is whether Google AI Overviews, Gemini, ChatGPT, and Claude name you when a domestic buyer asks for a recommendation in your category. We engineer visibility around Australian English search semantics, domestic competitor entity graphs, and strict Australian Privacy Principles (APPs) governing client data in AI model evaluations.

Entity Verification & Governance: DEJAN SEO PTY LTD, trading as DEJAN AI. ABN: 77 151 340 420. Corporate office: 29/97 Creek Street, Brisbane City QLD 4000, Australia. Fully compliant with Australian Privacy Principles (APPs) and zero-retention enterprise API policies. Client consultations conducted over dedicated video conference.

Frequently Asked Questions

Common commercial and technical questions regarding AI SEO engagements.

How much does AI SEO cost?

AI SEO at DEJAN starts at $5,000 AUD per month (plus GST for Australian clients). Our standalone Strategic AI Search Audit is also $5,000 AUD (+ GST), matching one month of retainer. Scope is determined by the number of entities tracked, the target geographic markets, and required technical implementation.

How long before we see measurable results?

On-site structured data fixes, content extraction updates, and crawl directives often reflect in AI answer citations within two to four weeks. Off-site entity building and broad consensus realignment typically compound over three to six months. In our OWAYO campaign, brand mention share rose from 1.5% to 8.0% over four months across 6,776 tracked AI answers.

Where is DEJAN based?

DEJAN SEO PTY LTD is an Australian company, ABN 77 151 340 420, registered in Queensland and running search campaigns since 2008. The team works remotely from Brisbane, Melbourne, Sydney, and Perth. We conduct meetings via video conference, serving Australian and global enterprises.

Is SEO still worth it in 2026?

Yes. Generative search engines assemble their answers directly from retrieved web pages. The pages an AI model can find, read, and trust determine which brands it recommends. While keyword rankings no longer tell the whole story, technical search indexability remains the foundation of all AI retrieval.

Can AI agents do SEO without human strategists?

AI agents excel at mechanical execution: crawling, log analysis, schema generation, entity mapping, and internal link modeling. They are unreliable on commercial judgment: which entities a brand should own, why a model associates a competitor with your category, and what content to publish. We build custom agents, and senior strategists sign off on all client recommendations.

Can DEJAN guarantee brand citations in ChatGPT or Google AI Overviews?

No legitimate agency can guarantee inclusion inside third-party language models. DEJAN uses mechanistic probing and mathematical optimization to align digital assets with the exact retrieval criteria search models require, maximizing citation probability.
