Rank in AI Search: LLM Guide

To rank in AI search, you should:

• Strengthen entity clarity across all profiles and platforms

• Increase high authority mentions in trusted sources

• Build content aligned with generative retrieval patterns

• Optimise for AI visibility using GEO (generative engine optimisation)

• Use structured data and tight semantic architecture

• Improve brand authority signals LLMs use to choose citations

Why AI Search Matters Now

For the first time in 20 years, people are bypassing Google and asking AI tools for answers. According to research by Gartner, nearly 80 percent of users now start with an AI assistant for complex queries. This shift is removing organic traffic from traditional SEO, forcing brands to adapt.

indexLab is one of the first agencies to specialise exclusively in generative engine optimisation, helping brands recover traffic lost to AI, strengthen visibility and get cited in LLM answers. As AI platforms become default search interfaces, businesses need strategies designed for these new retrieval systems.

What Is Generative Engine Optimisation?

Generative engine optimisation, often called AI SEO, is the practice of preparing your brand so LLMs can understand, verify and recommend it. GEO focuses on signals that AI models use to determine trust, topical authority and relevance.

According to Harvard Business Review, LLMs don’t “rank” pages. They choose the most reliable entities based on consistency, citations and semantic clarity. GEO aligns your entire digital ecosystem around these factors.

The Pillars of AI SEO

1. Entity Strength

LLMs rely heavily on entities, not pages. Strengthening your entity means clarifying who you are, what you do and why you’re credible. According to Google’s documentation on entities, entities allow models to retrieve consistent facts.

2. Authority Signals

Authority comes from high-trust sources. Links still matter, but so do citations in news outlets, industry reports, podcasts, and expert roundups.

3. Topical Depth

LLMs prefer sources that demonstrate expertise across an entire topic, not a single page. Long-term content clusters and comprehensive coverage help AI models select your brand as a leading entity.

4. AI-Focused Content Architecture

AI models use structures differently than Google. They use semantic patterns, consistent phrasing and well-aligned context. This means building clean, structured content architecture that mirrors LLM retrieval expectations.

5. Trust & Verification Layers

LLMs look for consistent data across platforms. Inconsistent NAP data or outdated bios reduce trust. According to Moz’s Local Consistency Report, mismatched profiles reduce entity reliability across AI systems.

How to Optimise for AI Visibility

1. Build High-Authority Mentions

LLMs rely on trusted sources like Wikipedia, Crunchbase, news sites and academic references. A well-optimised digital footprint creates more confidence for AI models to cite you.

2. Improve Semantic Structure

Use clear definitions, tight headers and coherent topics. AI crawlers prefer content that is predictable and well organised.

3. Strengthen Your Entity Profiles

Ensure all your profiles align: Google Business Profile, LinkedIn, Crunchbase, social platforms, About pages, and schema.

4. Create AI Friendly Pages

Pages should answer the question in the first paragraph, use clear bullets and be LLM ready. Models often use first-paragraph structured answers as candidate citations.

5. Add GEO-Specific Schema

Schema such as Organization, Person, FAQ, Product and Review help LLMs verify information.

Why Brands Are Losing Traffic to AI Search

Traffic is dropping because users ask AI tools questions that previously belonged to Google. Instead of clicking 10 links, they receive a synthesised answer.

Generative engines extract answers directly, citing brands only when they are confident. If your brand is not part of these retrieval datasets, you become invisible, even if you rank well in Google.

How indexLab Helps Brands Recover Traffic

indexLab focuses on:

• AI visibility optimisation

• GEO-driven content frameworks

• Authority signal development

• Entity strengthening

• Strategies to get cited by ChatGPT, Gemini and Perplexity

Our AI Visibility Audit identifies gaps in your entity structure, mentions, authority and content that prevent you from appearing in generative answers.

Future Predictions for AI SEO

According to McKinsey’s 2024 AI Future Report, AI assistants will account for most informational searches by 2026. This means entity authority, not keywords, will determine brand visibility.

Search will become conversational. Answer engines will become recommendation engines. And businesses optimised for LLM retrieval will dominate.

Counterarguments and Nuances

Some believe Google SEO will remain dominant. While YOY organic remains important, AI search grows faster. Realistically, both ecosystems will coexist. Optimising for LLMs future-proofs your brand regardless of platform shifts.

Another counterargument is that LLM visibility is unpredictable. While true, generative engines rely on consistent, verifiable data. Improving your entity, mentions and authority directly improves your likelihood of being cited.

Frequently Asked Questions

1. How long does it take to rank in AI search?

Most brands see early improvements in 60 to 120 days once entity and authority signals are strengthened.

2. Do backlinks still matter for AI SEO?

Yes, but brand mentions and authority citations often matter more for generative engines.

3. How do I get cited by ChatGPT or Perplexity?

You need clear entity signals, high-trust citations, and AI-friendly content structures so LLMs can confidently verify your information.

Conclusion

Ranking in AI search requires strengthening your entity, authority, content structure and visibility across the web. You rank by building clear, consistent information that LLMs can verify, trust and cite. These same steps help you recover traffic lost to AI and position your brand as an authoritative source in generative answers. By applying the core pillars of generative engine optimisation and enhancing your AI visibility, you make sure AI tools choose you over competitors and feature your brand in their responses.
