Entity-First SEO: How to Build the Knowledge Graph Signals That LLMs Use to Select Sources

LLMs do not rank websites. They select sources. And the brands that get selected share one thing in common: they exist as recognized entities inside knowledge graphs, not just as collections of keyword-optimized pages. If your company is invisible to the systems that map relationships between topics, brands, and expertise, no amount of traditional SEO will earn you citations in ChatGPT, Perplexity, or Google's AI Overviews.

This article breaks down the tactical steps required to build entity-level authority, explains why knowledge graph signals now determine AI visibility, and shows how Austin Heaton has used entity-first strategies to generate measurable results for B2B clients.

Why Entities Matter More Than Keywords in 2026

Google's Knowledge Graph has been central to search since 2012, but the rise of generative AI has made entity recognition the primary filter for source selection. 76% of AI Overview citations come from pages already ranking in Google's top 10 organic results, and the top 50 brands appearing in AI Overviews account for 28.9% of all citations. These are not random pages. They are entities that AI systems have mapped, validated, and learned to trust.

Entity-first SEO means shifting from "what keywords should we target" to "how does this brand exist in the knowledge graph." It requires consistent identity signals across every digital touchpoint: your website, structured data, third-party mentions, author profiles, and schema markup. When LLMs process a query, they do not crawl the web in real time for most responses. They rely on entity associations built during training and retrieval. If your brand is not a distinct, well-connected node in that graph, you are filtered out before the answer is even generated.

Austin Heaton has built his entire SEO and GEO consulting practice around this principle. His clients do not just rank for keywords. They become the entities that AI models cite.

The Four Pillars of Entity-First SEO

1. Structured Data as Your Entity's Blueprint

Schema markup is not optional for AI visibility. Structured data implementation increases AI Overview selection rates by 73%, and pages with entity-rich Knowledge Graph density of 15 or more connected entities see a 4.8x boost in citation probability. JSON-LD is Google's preferred format. At minimum, every B2B site needs Organization, Article, FAQPage, and Person schema deployed consistently across all key pages.

Austin implements advanced schema markup as part of every technical audit. This is not a one-time task. It is an ongoing process of ensuring that your brand, your people, and your content are machine-readable in ways that both Google and LLMs can parse accurately.

2. Cross-Platform Entity Consistency

LLMs validate entities by checking for consistent signals across multiple sources. Your brand name, leadership team, product descriptions, and core messaging must align across your website, LinkedIn, Crunchbase, industry directories, Wikipedia (if applicable), and press coverage. When these signals conflict, AI systems reduce confidence in your entity and select competitors instead.

This is where digital PR and authority building become critical. Branded web mentions show a stronger correlation with AI Overview appearances than backlinks or domain rating. Getting your brand mentioned in trusted publications as a recognized entity in your space is now directly tied to AI search visibility.

Austin has been featured as an expert source by SimilarWeb, Zapier, Fast Company, and the European Business Review. These are not vanity placements. They are entity-strengthening signals that LLMs use to validate source authority.

3. Topical Authority Through Content Clustering

Entities gain strength when they are connected to comprehensive topic coverage. Publishing a single article on "crypto payroll" does not make your brand an entity in that space. Publishing a cluster of 20 interconnected pieces covering every angle of crypto payroll, from compliance to payment rails to contractor onboarding, builds the topical depth that knowledge graphs require.

Austin's content strategy produces 12 to 20 SEO and GEO-optimized articles per month for each client. Every piece is engineered to reinforce entity associations, strengthen internal linking networks, and create the kind of semantic richness that AI models prefer. AI platforms cite content that is 25.7% fresher than what appears in traditional organic results, which means continuous publishing is not just beneficial. It is required.

4. AI-Specific Optimization (GEO/AEO)

Traditional SEO gets you indexed. Entity-first GEO and AEO optimization gets you cited. This means structuring content so that key answers appear in self-contained passages of 130 to 170 words, implementing FAQ sections that directly match conversational AI queries, and ensuring that every page includes the kind of verifiable claims and data points that LLMs prioritize when generating responses.

Austin pioneered this approach across his client portfolio. The results are measurable: 6,120 AI clicks with 927% growthand 5,130 ChatGPT referrals with 1,746% year-over-year growth across his B2B engagements.

Entity-First SEO in Action: Two Case Studies

Riseworks: From Unknown to Dominant Entity

Austin's work with Riseworks, a FinTech crypto payroll platform, demonstrates what happens when entity-first SEO is executed at scale. Over 12 months, he built Riseworks into a recognized entity across 100+ countries by combining structured data implementation, aggressive content clustering around crypto payroll topics, and cross-platform authority building. The result: 288% organic traffic growth, 575% AI search session expansion, and brand keyword searches growing between 150% and 1,149% across different terms. Riseworks went from fighting for visibility to owning the conversation in its category.

Lumanu: Entity Signals in 60 Days

The Lumanu engagement proves that entity-first tactics work on compressed timelines. Austin ran an LLM readiness audit, rebuilt schema markup, restructured internal linking, and produced purchase-intent content targeting 1,000+ conversational AI queries. He also secured DA40-80 backlinks that strengthened Lumanu's entity authority. Within 60 days: 656 AI search clicks, 101 conversions, and domain authority pushed above 60. ChatGPT alone delivered 566 referral clicks with 134% growth.

FAQ

What is entity-first SEO? Entity-first SEO is the practice of building your brand into a recognized entity within knowledge graphs so that search engines and LLMs can identify, validate, and cite your content. It goes beyond keyword targeting to focus on structured data, consistent brand signals, topical authority, and cross-platform presence.

How do LLMs decide which sources to cite? LLMs select sources based on entity authority, content freshness, semantic completeness, and cross-platform validation. Brands with strong knowledge graph signals, consistent identity across the web, and well-structured content are prioritized over sites that only optimize for traditional keyword rankings.

Does entity-first SEO replace traditional SEO? No. Traditional SEO remains the foundation. 76% of AI Overview citations come from pages ranking in Google's top 10. Entity-first SEO layers on top of that foundation by ensuring your brand is recognized as a trusted entity by both Google's Knowledge Graph and the AI models that generate answers.

How long does it take to build entity authority? Technical implementation of schema markup and entity consistency can be completed in 4 to 8 weeks. Building sustained topical authority and cross-platform recognition typically takes 3 to 6 months. Austin Heaton's Lumanu case study shows that significant AI search results are achievable within 60 days when execution is focused and aggressive.

Who should invest in entity-first SEO? Any B2B company that relies on organic search for lead generation and wants to maintain visibility as AI search grows. Companies in FinTech, SaaS, crypto, and Web3 are especially exposed because their buyers increasingly use AI tools to research and evaluate solutions before speaking to sales teams.
