Introduction
In the era of Generative Engine Optimisation (GEO) and AI-led search, visibility is no longer solely about keyword placements or backlink counts. Instead, Large Language Models (LLMs) and search engines prioritise entities—unambiguous, uniquely identifiable nodes of information. Auditing authority and entity signals is the process of assessing how well an AI understands who you are, what you do, and whether you can be trusted. This lesson provides a rigorous framework for evaluating these digital signals to ensure your brand is perceived as a primary source of truth.
The Shift from Keywords to Entities
Traditional SEO focused on strings (keywords). Modern visibility focuses on things (entities). An entity-based audit checks the 'connectedness' of a brand across the web. LLMs do not simply crawl pages; they synthesise information from massive datasets including Common Crawl, Wikipedia, and structured databases like Wikidata. If your entity signals are fragmented, contradictory, or absent, the AI will either ignore your brand or hallucinate incorrect information about it.
The Three Pillars of Entity Auditing
- Uniqueness: Is the entity clearly defined and distinct from competitors with similar names?
- Connectivity: Is the entity linked to high-authority nodes (e.g., industry bodies, major publications, government databases)?
- Consistency: Does the data (NAP: Name, Address, Phone; or core offerings) match across the entire digital ecosystem?
Step 1: Mapping the Knowledge Graph Presence
The first step of your audit is to determine if the entity already exists in major knowledge bases.
Google Knowledge Graph Audit
Search for the brand using its name. Check for a Knowledge Panel. If it exists, use the Google Knowledge Graph Search API to find the @id. This ID is the unique identifier (e.g., kgmid:/g/11bcdefg) that you should use in your structured data to 'claim' the entity.
Wikidata and Wikipedia
Check if the brand or its key personnel have Wikidata entries or Wikipedia pages. While not every SME qualifies for a Wikipedia page, every established brand should ideally have a Wikidata item. Wikidata provides the structured backbone for many LLMs. If the data there is outdated (e.g., listing a former CEO), this is a critical audit failure.
Step 2: Evaluating Schema.org Implementation
Schema markup is the 'contract' you sign with an AI to define who you are. A superficial audit just checks if Schema is present; an intermediate audit checks for relational density.
- Organization Schema: Does it include
sameAslinks to high-authority social profiles and directories? - Person Schema: Are the founders or C-suite executives linked to the organisation using
worksFororfounderproperties? - Entity Links: Are you using
aboutandmentionsproperties in your blog posts to link your content to established entities (e.g., mentioning a specific technology and linking to its Wikidata ID)?
Step 3: Assessing Digital Citations and E-E-A-T
AI models are trained on the 'consensus' of the web. If 50 high-authority sites say Company A is a leader in 'Ethical Fashion', the LLM will treat that as a fact.
The Citation Audit Checklist
- Consistency of Narrative: Is the brand described the same way on LinkedIn, Crunchbase, and its own website?
- Sentiment of Mentions: Use a sentiment analysis tool to check how the brand is discussed on forums like Reddit or industry-specific boards. LLMs are sensitive to 'reputation' data.
- Association with Quality: Is the brand mentioned alongside its competitors in 'Best of' lists? If you are missing from these lists, the AI ignores you during comparative prompts.
Worked Example: Auditing 'GreenGrid Solutions'
Scenario: A mid-sized B2B SaaS company, GreenGrid Solutions, provides AI-driven energy management. Despite great SEO, they are rarely mentioned in ChatGPT or Perplexity when users ask for 'best energy management software'.
The Audit Findings:
- Entitity Confusion: A search reveals a 'Green Grid' non-profit and a 'GreenGrid' construction firm. The SaaS company has no unique Knowledge Graph ID.
- Broken Links: Their Wikidata entry still lists a physical office they moved out of three years ago.
- Schema Gaps: Their
Organizationschema is basic. It lackssameAslinks to their Crunchbase profile and their award citations. - C-Suite Invisibility: The CEO has no personal brand presence, and the
Personschema is missing from the team page.
Resolution Plan:
- Update Wikidata with the correct headquarters and latest funding round.
- Implement advanced
Organizationschema with aknowsAboutproperty specifically targeting 'Energy Management Systems' and 'AI Optimization'. - Secure mentions in three high-authority trade journals to create 'expert peer' signals.
Step 4: Assessing Authorial Authority
LLMs increasingly look for the 'Author' entity to verify the reliability of a claim.
- Authorship Audit: Do your content creators have clear bios?
- Off-site Footprint: Does the author contribute to other reputable sites?
- Social Proof: Are the author’s LinkedIn or X profiles linked via
sameAsin the Article Schema?
Putting it into Practice
To conduct a mini-audit for a client or your own brand, follow these steps:
- Search the GKG: Use a tool like the 'Entity Explorer' to see if your brand has a Knowledge Graph node.
- Audit 'sameAs': List every platform your brand is on. Ensure the URL structure is identical across all profiles (e.g., all using https and the same trailing slash settings).
- Identify the 'Authority Gap': Find a competitor who is being cited by AI. Compare their 'Digital Footprint' to yours. Are they on Wikipedia? Do they have 10x more citations from educational (.edu) or government (.gov) sites?
- Validate Schema: Use the Schema Markup Validator. Look specifically for the
mentionsfield. If you aren't connecting your content to known entities, you are writing in a vacuum.
