Search has changed massively. Traditional SEO focused on ranking web pages in a list of blue links. Now, AI-powered platforms like ChatGPT, Gemini and Perplexity generate complete answers, not just links.
Instead of asking, ‘Where do we rank?‘, businesses now need to ask, ‘Why does AI recommend some brands, but ignore others?’
These systems don’t simply scan keywords. They interpret, synthesise and evaluate credibility across the wider web. That means visibility is no longer driven purely by technical SEO, but by broader signals of trust, authority and consistency.
Understanding LLM ranking factors is now essential for marketing leaders who want to remain discoverable in an AI-driven industry. In this article, we’ll explore:
- How AI search differs from traditional SEO ranking signals
- The core source-selection signals that influence AI recommendations
- Practical steps to improve your AI visibility (you can test your brand now with our AI visibility tool)
How AI Search Differs from Traditional SEO
Traditional SEO has historically relied on measurable page-level signals such as:
- Keyword targeting
- Keyword density
- Backlinks
- Domain authority
- Technical performance
AI search, however, evaluates credibility very differently.
Rather than assessing individual pages in isolation, AI systems analyse patterns of trust and authority across the broader web. These include:
- Entity recognition
- Contextual authority
- Content consistency
- Verifiable trust signals
This means AI engines are less concerned with how well one page ranks and are more focused on how reliably your brand appears, is referenced and is supported across multiple sources.
Visibility in AI-generated recommendations therefore, depends on broader digital authority, not just technical optimisation. Search engine optimisation strategies must now evolve to address AI-specific ranking factors. Effective SEO optimisation for AI search requires a focus on semantic relevance and content quality, rather than just traditional tactics.
Core AI Source-Selection Signals
A. Entities
An entity is a clearly defined person, organisation, product or concept that can be recognised consistently across different platforms and sources.
AI systems rely heavily on entity clarity to determine whether a brand is legitimate and trustworthy. When your business name, leadership team or services are referenced consistently across authoritative websites, directories and media coverage, AI platforms gain confidence in recommending you.
Conversely, inconsistent naming conventions, incomplete profiles or fragmented online presence can weaken that confidence.
B. Authority
Authority signals remain important, but AI evaluates them more holistically.
These signals include:
- Expert authorship
- Backlinks from trusted sites
- Media mentions
- Citations in credible publications
- Visible author credentials
- Third-party mentions from reputable sources
- Citations from credible sources
Content attributed to identifiable experts is significantly more likely to be surfaced than anonymous or generic material. Demonstrating genuine expertise, through detailed, specific and demonstrable knowledge, helps establish authority in the eyes of AI models and sets authoritative content apart from generic information.
C. Consistency
AI search models cross-reference information across:
- Your website
- Social media platforms
- Business directories
- Press mentions
- Third-party profiles
Consistent messaging, branding and business details strengthen AI confidence in the reliability of your organisation. Structured data and uniform naming conventions further improve this reliability.
D. Proof & Evidence
AI systems favour content that demonstrates real-world credibility through:
- Statistics
- Case studies
- Original data
- Transparent sourcing
Up-to-date publication dates and regularly updated existing content, especially when enhanced with citations and AI optimisation, further enhance credibility and the likelihood of being included in AI-generated responses.
Claims that cannot be verified, or are unsupported by evidence, are far less likely to be included in AI-generated responses.
Where ChatGPT, Gemini & Perplexity Pull From
While each platform operates differently, observable patterns suggest these systems typically draw from:
- Publicly available web content
- High-authority domains
- Structured website information
- Frequently cited sources
Features like AI overviews and Google’s AI Overviews play a significant role in how content is selected and presented in AI-powered search results. Optimising for AI mentions and understanding how AI mode influences content selection can improve the chances of being cited by these platforms.
Importantly, they don’t rely on a single ranking list in the way traditional search engines do. Instead, they aggregate signals from across the digital ecosystem to determine which sources appear trustworthy enough to include in generated answers.
Technical Optimisation for AI Search
Technical optimisation is no longer just about climbing the ranks in traditional search engines. It’s now a critical foundation for being discovered and recommended by AI-powered platforms. As AI models like ChatGPT, Gemini and Perplexity influence how users find information, ensuring your website is technically sound is essential for search visibility and authority.
While traditional SEO factors such as page speed, mobile responsiveness and crawlability remain important, AI search engines require an extra layer of clarity and structure. AI models prioritise content that is well-structured, easy to interpret and supported by clear technical signals.
Key technical optimisation strategies for AI search include:
- Implementing Structured Data & Schema Markup: Use schema markup to define your business, services, authors and FAQs. This helps AI crawlers and large language models accurately identify entities, relationships and key information on your site, boosting your chances of being referenced in AI responses and overviews.
- Maintaining a Logical Site Hierarchy: Organise your website content with clear navigation, headings and internal linking. A logical hierarchy makes it easier for AI systems to understand the context and relevance of your pages, supporting both traditional SEO and AI search ranking factors.
- Optimising for Crawlability and Indexing: Ensure your site is easily accessible to both search engine bots and AI crawlers. Use clean URLs, avoid duplicate content, and regularly update your sitemap to help AI models discover and process your latest content.
- Enhancing Page Speed and Performance: Fast-loading, technically robust websites are favoured by both traditional search engines and AI platforms. Monitor key metrics like load times, mobile usability and core web vitals to provide a seamless user experience and support AI-driven visibility.
- Ensuring Content is Machine-Readable: Use clear, consistent formatting, avoid excessive keyword stuffing and structure your content with proper headings and metadata. This allows AI models to extract and synthesise information more accurately, increasing your chances of being included in AI-generated answers.
By focusing on these technical optimisation strategies, you not only improve your traditional SEO performance but also position your business for greater visibility in the evolving world of AI search. For finance providers and SMEs, this means your services, expertise and brand are more likely to be surfaced when potential customers turn to AI tools for business funding advice and solutions.

Factors That Reduce AI Visibility
Some practices can actively weaken your chances of being recommended by AI systems:
- Publishing thin AI-generated content without human oversight, generic blog posts lacking depth or expertise are less likely to be recommended
- Inconsistent brand information across platforms
- Lack of author attribution or expertise signals
- Over-optimising keywords instead of building authority
AI search platforms are designed to favour trustworthiness rather than volume. They reward content that delivers just what users need, rather than superficial or irrelevant information.
Recommended Approach
AI search visibility doesn’t replace traditional SEO, but it does build on it.
The brands most frequently recommended by AI systems are those that demonstrate:
- Clear entity definition
- Recognised authority
- Consistent messaging
- Verifiable proof
Following E-E-A-T (Experience, Expertise, Authoritativeness and Trustworthiness) guidelines is essential for building trust and authority in AI-driven search. Delivering real value to users is more important than ever for AI recommendations, as both search engines and AI algorithms prioritise content that genuinely benefits and engages audiences. Strengthening your digital presence across platforms, including through social media marketing, increases your chances of being cited by AI systems and enhances your overall online authority. AI models use natural language processing to interpret queries and evaluate content relevance, so it’s important to write in a way that aligns with these technologies.
In practical terms, the most effective strategy is to integrate established SEO practices with structured AI visibility optimisation.
