Entity-Based SEO and Semantic Search: Explained

Today’s search engines, powered by sophisticated artificial intelligence and machine learning algorithms, seek to understand the true meaning behind both search queries and web content. This evolution has given birth to two interconnected concepts that are reshaping how we approach SEO: entity-based SEO and semantic search.

Understanding Entity-Based SEO

Entity-based SEO represents a fundamental shift from traditional keyword-focused strategies to a more nuanced approach centred on entities—distinct, well-defined concepts that search engines can identify, understand, and connect to other related concepts. An entity might be a person, place, organisation, product, concept, or any other noun that exists in the real world or conceptual space.

In 2025, meaning wins. Every time. This statement encapsulates the core principle of entity-based SEO: it’s not about what words appear on your page, but about the concepts and relationships those words represent.

Consider the difference between traditional keyword targeting and entity-based approaches. Whilst traditional SEO might focus on ranking for “best Italian restaurant,” entity-based SEO recognises that this query involves multiple entities: cuisine type (Italian), business category (restaurant), and quality indicators (best). Modern search engines understand these relationships and can provide more contextually relevant results.

The Mechanics of Semantic Search

Semantic search goes hand-in-hand with entity-based SEO, focusing on understanding the intent and contextual meaning behind search queries rather than simply matching keywords. Semantic SEO is all about helping search engines understand what your content actually means — not just what words it contains.

This technology enables search engines to:

• Understand synonyms and related terms naturally
• Recognise context and user intent
• Connect related concepts across different pieces of content
• Provide more accurate and relevant search results
• Handle conversational and complex queries more effectively

The implications for content creators and SEO professionals are profound. Rather than creating separate pages for closely related keywords, semantic search encourages the development of comprehensive, topic-focused content that addresses user intent holistically.

How Entities Transform Search Results

When search engines process queries using entity-based understanding, they create a web of interconnected concepts. For instance, if someone searches for “sustainable energy solutions,” the search engine doesn’t just look for pages containing those exact words. Instead, it identifies entities such as:

• Renewable energy (solar, wind, hydroelectric)
• Environmental sustainability
• Energy efficiency technologies
• Government policies and incentives
• Companies operating in the clean energy sector

This entity recognition allows search engines to surface relevant content that might not contain the exact search terms but covers related concepts comprehensively.

Practical Applications of Entity-Based SEO

Topic Clusters and Content Architecture

Modern SEO strategies increasingly rely on topic clusters—groups of related content pieces that comprehensively cover a subject area. Semantic SEO relies on topic clusters, internal linking, entity optimization, and structured data to help search engines understand context and relationships.

For example, a financial services company might create a topic cluster around “mortgage advice” that includes:

• Pillar content: “Complete Guide to Getting a Mortgage”
• Supporting content: “First-time buyer programmes,” “Mortgage rates explained,” “Property valuation process,” “Legal requirements for home purchases”

Each piece of content targets specific entities whilst contributing to the overall topic authority.

Schema Markup and Structured Data

Schema implementation has become standard in SEO communities by 2025. Structured data markup helps search engines identify and understand entities within your content. This might include:

• Organisation schema for business information
• Product schema for e-commerce items
• Article schema for blog posts and news content
• Local business schema for location-based services
• Review the schema for customer testimonials

Content Depth and Expertise

Entity-based SEO rewards comprehensive, authoritative content. Rather than creating thin pages targeting specific keywords, successful strategies focus on developing detailed resources that demonstrate genuine expertise and cover topics thoroughly.

Generic Examples of Entity-Based SEO in Action

Example 1: Health and Wellness Website

A health and wellness website looking to rank for fitness-related queries might create content around the entity “strength training.” Rather than separate pages for “weight lifting,” “resistance training,” and “muscle building,” they would develop comprehensive content that:

• Defines strength training as an entity
• Connects it to related entities (muscle groups, equipment types, training methodologies)
• Addresses common user intents (beginner guides, advanced techniques, injury prevention)
• Links to supporting content about nutrition, recovery, and specific exercises

Example 2: Technology Consultancy

A technology consultancy might focus on the entity “digital transformation.” Their content strategy would encompass:

• Core pillar content explaining digital transformation concepts
• Supporting articles on related entities (cloud computing, automation, data analytics, cybersecurity)
• Case studies demonstrating successful implementations
• Industry-specific guidance connecting digital transformation to various business sectors

Example 3: Educational Institution

An educational institution targeting prospective students might build content around “professional development” as a central entity, connecting it to:

• Specific degree programmes and certifications
• Career outcomes and industry connections
• Skills development and competency frameworks
• Alumni success stories and networking opportunities

Niche Term Domination Strategy

The agency has successfully targeted highly specific, niche search terms by building comprehensive entity relationships. For instance, they’ve developed authority around “Preston SEO consultancy” by:

Creating Entity Connections: Rather than simply targeting the keyword phrase, they’ve built content that connects Preston as a location entity to broader concepts like Lancashire business growth, North West digital marketing trends, and UK SME online visibility challenges.

Industry-Specific Content: They’ve developed specialised content for entities within specific industries prevalent in the Preston and Lancashire area, such as manufacturing businesses, professional services, and retail sectors. This approach allows them to rank for terms like “Preston manufacturing company SEO” and “Lancashire professional services digital marketing.”

Technical Expertise Demonstration: By creating comprehensive content around technical SEO entities—such as Core Web Vitals, structured data implementation, and local search factors—they’ve established authority for terms like “Preston technical SEO audit” and “Lancashire website performance optimisation.”

Content Architecture Excellence

Pillar Content Development: They’ve created comprehensive guides that serve as pillar content for major entities like “local SEO,” “e-commerce optimisation,” and “content marketing strategy.” Each pillar connects to numerous supporting articles that explore related sub-entities.

Local Entity Integration: Every piece of content strategically incorporates local entities—not just Preston, but related locations like Blackpool, Lancaster, and Manchester—creating a comprehensive local SEO footprint that captures related search traffic.

Industry Authority Building: By consistently publishing content that connects digital marketing entities to local business challenges and opportunities, they’ve built recognition as thought leaders in the North West digital marketing space.

Measurable Results

This entity-based approach has enabled Module SEO to achieve:

• Dominance in highly specific niche terms that competitors overlook

Their success demonstrates how smaller, local agencies can compete effectively against larger competitors by leveraging entity-based SEO principles to build authority in specific niches whilst maintaining broader market visibility.

The Future of Entity-Based SEO

In 2025, the most competitive brands will be those that embrace an entity-first approach to SEO. As artificial intelligence continues to evolve, we can expect entity-based SEO to become even more sophisticated.

By mid-2025, AI Overviews were already present for nearly one in five US search queries. This trend towards AI-generated search results reinforces the importance of creating content that machines can understand and contextualise effectively.

Future developments are likely to include:

• More sophisticated entity recognition and relationship mapping
• Increased importance of expertise, authority, and trustworthiness signals
• Greater integration between voice search and entity understanding
• Enhanced personalisation based on entity preferences and behaviour patterns

Begin by identifying the core entities relevant to your business or industry. Use tools to understand entity relationships and search patterns around these concepts.

Develop Topic Authority

Create comprehensive, interconnected content that demonstrates deep expertise in your chosen entities. Focus on quality and depth rather than quantity.

Optimise Technical Infrastructure

Implement structured data markup, ensure fast loading times, and create a clear site architecture that helps search engines understand your content relationships.

Monitor and Adapt
