Learn how.","keywords":["@id","Entities","Entity","Entity Linking","Explainers","External Entity Linking","Internal Entity Linking"],"articleBody":"In the age of semantic search, search engines no longer rely solely on keywords to understand content. Instead, they identify entities\u2014distinct and unique things such as people, places, organizations, and concepts.\nBy structuring your content with clearly defined entities and their relationships, you create a Content Knowledge Graph that search engines can reference to understand context and deliver more relevant search results.\nBut how do you identify and define the entities within your content that you want your organization to be known for?\nOne of the most effective ways is through Schema Markup. By structuring your data using the Schema.org vocabulary and assigning unique resource identifiers (@id) to the entities in your content, you create machine-readable connections that help search engines accurately interpret and link relevant concepts.\nWhy Entities Matter in SEO\nEntities enable search engines to move beyond basic keyword matching and toward a more contextual understanding of content.\nTake the word \u201cApple,\u201d for example. Without proper context, search engines may not know whether you\u2019re referring to:\n\nA company (Apple Inc.)\nA fruit\nA place (like Apple, Oklahoma)\n\nIf entities aren\u2019t clearly defined, search engines may misinterpret the content or miss important connections entirely.\nSchema Markup provides the necessary structure and context to ensure that your entities are correctly understood.\nHow Schema Markup Identifies Entities\nTo define an entity using Schema Markup, you assign it a unique @id. This identifier functions as a Uniform Resource Identifier (URI) that distinguishes the entity and makes it referenceable across your site and beyond.\nUsing @id to Define Unique Entities\nLet\u2019s say you have an author page for Mark van Berkel. You can define him as a unique entity like this:\n\nOnce the @id is assigned, you can enrich the entity with properties to provide more context.\nAdding Properties to Describe an Entity\nSchema Markup allows you to describe an entity using Schema.org properties, which define attributes and relationships between entities to enhance search engines\u2019 understanding of the entity.\nFor instance, expanding on our previous example, Mark van Berkel\u2019s author page states that he is the Co-founder and CTO of Schema App, and that he knows about semantic technology. We can use the Schema.org properties to further describe him as an entity.\n\nIf Mark is mentioned elsewhere on your site\u2014say in a blog post or on a webinar page\u2014you can reference this same @id to maintain consistency. Without it, search engines may treat each mention of \u201cMark van Berkel\u201d as a separate entity, leading to fragmented understanding.\nHow to Establish Relationships Between Entities\nEntities don\u2019t exist in isolation\u2014they are defined not only by their attributes, but by their relationships with other entities.\nSchema Markup enables you to connect entities within your website content and across the web, creating a structured network of information.\nContinuing our example, if Mark van Berkel writes a blog post, you can use the author property to link the article to the author entity:\n\nBy defining these relationships, search engines can accurately associate authors with their work\u2014strengthening their perceived expertise and authority.\nWhy is it Important to Identify Entities Using @ids?\nUsing @id doesn\u2019t just improve internal consistency\u2014it also allows you to link your entities to external knowledge bases, expanding your presence in the broader web of data.\nLinking to External Knowledge Graphs\nYour website isn\u2019t the only source for defining entities. Many authoritative databases, such as Wikidata, Wikipedia, and Google\u2019s Knowledge Graph, also maintain entity identifiers.\nBy linking your @id to these authoritative sources using the sameAs property, you provide additional clarity and credibility to search engines.\nFor example, referencing Apple Inc. might look like this:\n\nThis helps search engines confidently associate your content with the correct entity in their Knowledge Graph.\nHow Schema App Helps You Define and Identify Entities\nManually identifying and linking entities at scale can be challenging. At Schema App, we simplify this process with our Highlighter and External Entity Linking (EEL) feature.\nHow Schema App\u2019s Highlighter and External Entity Linking Works\n\nSchema App\u2019s Highlighter allows you to deploy dynamic Schema Markup at scale, ensuring that every key entity has an @id.\nExternal Entity Linking (EEL) automatically identifies and links your entities to authoritative sources like Wikipedia, Wikidata, and Google\u2019s Knowledge Graph.\n\nBy leveraging these tools, you can enhance entity recognition, strengthen your content\u2019s authority, and improve search engine understanding.\nReady to Implement Entity Linking at Scale?\nIf you want to improve how search engines understand and connect your content, Schema App can help.
