Now, more than ever before, his vision is becoming a reality, because in addition to humans, AI and Large Language Models need this data to deliver on new experiences.\nIn this article, we\u2019ll explore what Linked Data is and share examples of Linked Data projects which many in the SEO and tech community refer to as knowledge graphs.\nWhat is Linked Data? \nLinked Data is a set of design principles for publishing machine-readable interconnected data on the web. \nThe term \u201cLinked Data\u201d first appeared in 2006 when Tim Berners-Lee published a design note about the Semantic Web. He sought to use Linked Data as a way of representing the relationship between different things on the internet. The internet would then become a huge database of interconnected (linked) objects (data) and become the Semantic Web.\nBusinesses or enterprises can use Linked Data to define things and the relationships between them. For example, companies like Facebook, Twitter, and LinkedIn have undertaken Linked Data projects to represent social networks. When users perform actions like connecting to other users or liking and resharing content, these actions are reflected in a graphical representation of who they are, who they know and what they like.\n<img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-14493 size-us_450_0 aligncenter\" src=\"https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-450x415.png?strip=all&lossy=1&ssl=1\" alt=\"Example of graphical representation of users actions forming linked data\" width=\"450\" height=\"415\" srcset=\"https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-450x415.png?strip=all&lossy=1&ssl=1 450w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-300x277.png?strip=all&lossy=1&ssl=1 300w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-600x553.png?strip=all&lossy=1&ssl=1 600w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-768x708.png?strip=all&lossy=1&ssl=1 768w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-651x600.png?strip=all&lossy=1&ssl=1 651w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-80x74.png?strip=all&lossy=1&ssl=1 80w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-252x232.png?strip=all&lossy=1&ssl=1 252w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-200x184.png?strip=all&lossy=1&ssl=1 200w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-65x60.png?strip=all&lossy=1&ssl=1 65w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-108x100.png?strip=all&lossy=1&ssl=1 108w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-140x129.png?strip=all&lossy=1&ssl=1 140w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-400x369.png?strip=all&lossy=1&ssl=1 400w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-220x203.png?strip=all&lossy=1&ssl=1 220w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-100x92.png?strip=all&lossy=1&ssl=1 100w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-150x138.png?strip=all&lossy=1&ssl=1 150w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-30x28.png?strip=all&lossy=1&ssl=1 30w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-50x46.png?strip=all&lossy=1&ssl=1 50w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-33x30.png?strip=all&lossy=1&ssl=1 33w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data-38x35.png?strip=all&lossy=1&ssl=1 38w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Example-of-graphical-representation-of-users-actions-forming-linked-data.png?strip=all&lossy=1&ssl=1 900w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/>\nAs a result, these social media platforms can gain knowledge about a person and enable things like targeted advertising to users based on their relationship to other things. However, the knowledge that these social media platforms derive from their Linked Data is proprietary and not licensed for external use.\nThis led to a movement calling for Linked Data to be open for people to use freely for research purposes \u2013 especially from governmental organizations, and other public institutions such as museums.\nIn 2010, Tim Berners-Lee modified his original design note to add principles for Linked Open Data, a variation of Linked Data permitting reuse.\nLinked Open Data (LOD) is Linked Data released under an open license, which allows others to freely access and reuse it.\nPrinciples of Linked Data\nWhen Tim Berners-Lee first published the design note about Linked Data, he defined the 4 principles of Linked Data. Based on this note, people or machines would be able to explore the web of data if it adhered to the following 4 principles:\n1. Use URIs as names for things\nA URI (Uniform Resource Identifier) is a string of characters that identifies a resource. It provides a consistent way to identify resources across different systems and protocols.  A resource (also known as an entity) is anything that can be identified and described, such as people, places, objects, or concepts.\n2. Use HTTP [or HTTPS] URIs so that people can look up those names\nAn HTTP\/HTTPS URI is a specific type of URI that uses the Hypertext Transfer Protocol or Protocol Secure. This means that when you access an HTTP\/HTTPS URI in a web browser or through an HTTP request, you should get back information about the resource it identifies.\n3. When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)\nWhen a user or application accesses a Uniform Resource Identifier (URI), the information returned should be both meaningful and structured according to standardized semantic technologies, specifically RDF (for expressing the data) and SPARQL (for querying the data).\n4. Include links to other URIs so that they can discover more things\nWhen you create or publish data, you should include links within your data to other resources or entities (in the form of URIs). These URIs can point to related or relevant information, such as other resources, definitions, or attributes. This provides additional context about your own resources.\nBy following these principles, you contribute to a growing network of interlinked data across the web. This allows consumers of the data (human or machine) to gather more insights, context, and knowledge.\nThe benefit of using Linked Data for SEO\nLinked Data is great for SEO because it can provide search engines with more contextual knowledge about your content. Search engines now look at relevancy to provide searchers with the most accurate results.\nOne of the most common forms of linked data on the web is Schema Markup which primarily describes webpage contents for search engines. Schema Markup uses the Schema.org vocabulary which can express RDF linked data in formats like JSON-LD.\nWhen you use machine-readable code like Schema Markup to express the relationship between the entities on your site, it helps search engines understand and derive knowledge about your organization.\nFor example, if you have a page about your organization\u2019s proprietary software application, you can tell search engines that this software application is provided by your organization by linking the URI that contains all the information about your organization to the provider property in the markup for your page.\n{\n  \"@context\": \"http:\/\/schema.org\/\",\n  \"@type\": \"SoftwareApplication\",\n  \"@id\": \"https:\/\/www.schemaapp.com\/solutions\/schema-app-highlighter\/#SoftwareApplication\",\n  \"name\": \"Schema App Highlighter\",\n  \"description\": \"Use the Schema App Highlighter to customize your Schema Markup...\",\n  \"applicationCategory\": \"Search Engine Optimization\",\n  \"provider\": {\n    \"@type\": \"Organization\",\n    \"@id\": \"https:\/\/www.schemaapp.com\/#Organization\",\n    \"url\": \"https:\/\/www.schemaapp.com\/\",\n    \"name\": \"Schema App\",\n    \"description\": \"Schema App is an end-to-end Schema Markup solution...\",\n    \"telephone\": \"18554448624\",\n    \"email\": \"support@schemaapp.com\",\n    \"areaServed\": \"http:\/\/www.wikidata.org\/entity\/Q13780930\",\n  }\n}\nThe URI appears in JSON-LD in the @id attribute. Your Schema Markup can be generated and authored without including identifiers (@id). Search engines like Google will still read it and make it eligible for rich results. However, by generating your Schema Markup with a URI, you can link it to other entities.\nYou can also link your Schema Markup to other Linked Data projects to be more explicit about the entities you are talking about on your website.\nFor example, if you are talking about football on a page, this can be confusing to search engines because the term football can mean different things depending on where you are in the world. You can help search engines disambiguate which football you are referring to by linking your page to the same entity described in Wikipedia, Wikidata or Google\u2019s Knowledge Graph.\nIf you are talking about American football, you can use the sameAs property in your Schema Markup to link to the same entity on Wikipedia, Wikidata or Google\u2019s Knowledge graph.\n{\n  \"@context\": \"http:\/\/schema.org\/\",\n  \"@type\": \"BlogPosting\",\n  \"@id\": \"https:\/\/www.schemaapp.com\/blog\/what-is-football\/#BlogPosting\",\n  \"url\": \"https:\/\/www.schemaapp.com\/blog\/what-is-football\/\",\n  \"name\": \"What is Football?\",\n  \"headline\": \"What is Football?\",\n  \"description\": \"Learn about the rules and history of Football.\",\n  \"mentions\": {\n    \"@type\": \"Thing\",\n    \"name\": \"Football\",\n    \"sameAs\": \"https:\/\/www.wikidata.org\/wiki\/Q41323\",\n    \"sameAs\": \"https:\/\/en.wikipedia.org\/wiki\/American_football\",\n    \"sameAs\": \"kg:\/m\/0jm_\",\n  }\n}\nHowever, applying Linked Data on your site can be a technically challenging task.\n\nQuality \u2013 You need to keep the data up-to-date, accurate and complete.\nScalability \u2013 Handling this huge volume of data can be time-consuming and resource-intensive.\nExpertise \u2013 Transforming your content into Linked Data requires knowledge of the technologies to do this work and how to apply them effectively.\nSustainability \u2013 You need resources to maintain the data quality.\n\nExamples of Linked Data Projects in SEO\nThere are many examples of Linked Data Projects in use today. These Linked Data Projects are also often referred to as Knowledge Graphs.\nKnowledge graphs are a collection of related entities expressed as RDF triples. When you use Schema Markup to express the relationship between two entities on your site, you are implementing Linked Data. When you connect the various entities on your site, you are effectively developing an internal knowledge graph about your organization. Your internal knowledge graph becomes even more robust and useful when linked to other external knowledge graphs.\nSome of these external knowledge graphs are also useful for search engine optimization (SEO) purposes. SEO teams can connect their internal knowledge graphs to external knowledge graphs to tell search engines that the entity defined in this external knowledge graph is the same as the entity defined on their website.\nLet\u2019s explore some of the Linked Data Projects \/ External Knowledge Graphs pertaining to the SEO world.\nGoogle\u2019s Knowledge Graph\nGoogle\u2019s Knowledge Graph is a knowledge database that Google uses to provide quick answers to queries about certain topics or entities (people, places, organizations, things). This can show up in search in the form of a knowledge panel. The knowledge panel contains a snapshot of information about the topic based on Google\u2019s understanding of the available content on the internet.\n<img decoding=\"async\" class=\"wp-image-14494 size-us_0_600 aligncenter\" src=\"https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-315x600.png?strip=all&lossy=1&ssl=1\" alt=\"Example of Berkshire Hathaway's Knowledge Panel on Google\" width=\"315\" height=\"600\" srcset=\"https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-315x600.png?strip=all&lossy=1&ssl=1 315w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-158x300.png?strip=all&lossy=1&ssl=1 158w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-80x152.png?strip=all&lossy=1&ssl=1 80w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-122x232.png?strip=all&lossy=1&ssl=1 122w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-200x381.png?strip=all&lossy=1&ssl=1 200w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-32x60.png?strip=all&lossy=1&ssl=1 32w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-53x100.png?strip=all&lossy=1&ssl=1 53w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-140x267.png?strip=all&lossy=1&ssl=1 140w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-220x419.png?strip=all&lossy=1&ssl=1 220w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-100x190.png?strip=all&lossy=1&ssl=1 100w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-150x286.png?strip=all&lossy=1&ssl=1 150w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-16x30.png?strip=all&lossy=1&ssl=1 16w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-50x95.png?strip=all&lossy=1&ssl=1 50w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM-18x35.png?strip=all&lossy=1&ssl=1 18w, https:\/\/ezk8caoodod.exactdn.com\/wp-content\/uploads\/2023\/10\/Screenshot-2023-10-25-at-8.34.02\u202fAM.png?strip=all&lossy=1&ssl=1 395w\" sizes=\"(max-width: 315px) 100vw, 315px\" \/>\nThe story of Google\u2019s Knowledge Graph starts with Freebase, a Metaweb project launched in 2007. Freebase was described as \u201ca system for building the synapses for the global brain\u201d. This massive knowledge base, which formally became a linked open data project in 2008, was one of the largest and most ambitious Linked Data projects of its time.\nIn 2010, Google acquired Freebase from Metaweb and imported Freebase\u2019s massive knowledge base into Google\u2019s proprietary Knowledge Graph. Soon after, Google introduced their Knowledge Graph in their famous \u2018things, not strings\u2019 article, indicating a pivot from lexical to semantic search.\nThe Google Knowledge Graph is a Linked Data project because it adheres to the 4 principles of Linked Data. However, the Google Knowledge Graph is NOT a linked open data project because the data is not published with an open license. That being said, it is possible to find identifiers (URIs) for entities in the Google Knowledge Graph and link them to your own knowledge graph.\nHow to access Google\u2019s Knowledge Graph?\nThe Google Knowledge Graph has a search API that is read-only. You\u2019ll notice the URIs in the output are structured with a \u201ckg\u201d namespace (which stands in for http:\/\/g.co\/kg) and either \/m\/ or \/g\/ before a string of characters. These identifiers are called \u201cmid\u201ds, or Machine IDs, which is a legacy term from Freebase.\nFor example, the Freebase object for the entity Barack Obama has the mid \/m\/02mjmr. This same entity can be accessed in Google\u2019s Knowledge Graph by going to https:\/\/www.google.com\/search?kgmid=\/m\/02mjmr. The entity has the same mid in Google\u2019s Knowledge Graph.\nHow is Google\u2019s Knowledge Graph used?\nGoogle uses its knowledge graph to improve the search experience on its search engine. When you search for something like \u201cBerkshire Hathaway\u201d, Google identifies the entities in your query and provides information on those entities from both its knowledge graph and other sources on the web. One of the most common sources is Wikipedia.\nWikipedia & DBpedia\nWikipedia is a free, collaborative online encyclopedia composed of more than 61 million articles. Wikipedia articles represent entities, such as people, places, events, concepts, or other things.\nThe URLs of Wikipedia articles also function as URIs for the entities they represent. So the URL https:\/\/en.wikipedia.org\/wiki\/Kathryn_Janeway is both an article that can be visited on the web, and the URI that represents the entity, Kathryn Janeway, in Wikipedia\u2019s knowledge base.\nArticles within Wikipedia contain structured elements, as well as links to other related entities. While Wikipedia on its own isn\u2019t a traditional Linked Data project, it plays a significant role in the Linked Data ecosystem on the web, particularly with regard to DBpedia and Wikidata.\nDBpedia is a linked open data project that extracts information from Wikipedia to generate RDF triples, which can be semantically queried alongside other related datasets. It pulls information from the structured elements of Wikipedia pages, such as \u201cinfobox\u201d tables like this:\n<img decoding=\"async\" class=\"size-full wp-image-14495 aligncenter\"

sizes=\"(max-width: 400px) 100vw, 400px\" \/>Post from Wikipedia Engineering Manager, Joseph S.; inspired by https:\/\/xkcd.com\/2347\/\nWikidata\nWikidata is a collaborative Linked Open Data project that\u2019s been operated by the Wikimedia Foundation since its inception in 2012 (source).\nDespite having Wiki in its name, Wikidata is not the same as Wikipedia. Wikidata is a broader knowledge base than Wikipedia, containing data about a wider range of topics. Wikidata also allows users to create RDF Linked Data directly.\nEven though Wikidata and DBpedia are both Linked Open Data projects related to Wikipedia, they have different aims and serve different functions.\nDBpedia extracts information to generate Linked Data from Wikipedia\u2019s structured sources like infoboxes. As a result, DBpedia treats the knowledge derived as facts.\nRather than extracting information from Wikipedia, Wikidata creates Linked Data for Wikipedia (source). Since Wikidata also treats statements within the Linked Data as claims rather than facts, these statements must be annotated with provenance information (i.e. who made each claim).\nInstead of \u201cmid\u201ds (identifiers used by Freebase\/Google\u2019s Knowledge Graph), each entity in Wikidata has a \u201cqid\u201d.\nHere\u2019s a summary of the identifiers for each of the Linked Data projects listed above.\n\n\n\nLinked Data Project\nIdentifier\nExample\n\n\nGoogle\u2019s Knowledge Graph\nMachine Identifier (Mid)\nkg:\/m\/0k8z\n\n\nWikipedia\nWikipedia titles\nhttps:\/\/en.wikipedia.org\/wiki\/Apple_Inc.\n\n\nWikidata\nQid\nhttps:\/\/www.wikidata.org\/entity\/Q312\n\n\n\nGoogle\u2019s Knowledge Graph, Wikipedia, and Wikidata are the most common Linked Data projects utilized in SEO. When we talk about connecting your Schema Markup to external authoritative knowledge bases at Schema App, these are the external knowledge graphs we are referring to.\nHow to use Linked Data with Schema App\nAt Schema App, our semantic technologies allow SEO teams to easily generate Linked Data for their website content.\nGenerate URIs for your entities\nWhen you publish your Schema Markup using the Schema App Editor or Highlighter, our tool automatically generates HTTPS URIs for the entities you define in your Schema Markup. These URIs, which appear in the @id attribute, link to the URLs of the pages where they\u2019ve been mentioned.\nFor example, we publish Organization markup to our Schema App home page. The URI for our Organization entity would then be the URL of our homepage + #Organization \u2013 https:\/\/www.schemaapp.com\/#Organization. If you navigate to this URI, it will take you to the page about our Organization.\nCreating URIs for entities on your site allows you to easily link to those entities in your Schema Markup. For example, if your organization has published a blog post you can link your Organization URI to the publisher property in your BlogPosting Schema Markup.\n{\n  \"@context\": \"http:\/\/schema.org\/\",\n  \"@type\": \"BlogPosting\",\n  \"@id\": \"https:\/\/www.schemaapp.com\/schema-markup\/what-is-a-rich-result\/#BlogPosting\",\n  \"url\": \"https:\/\/www.schemaapp.com\/schema-markup\/what-is-a-rich-result\/\",\n  \"name\": \"What is a Rich Result?\",\n  \"headline\": \"What is a Rich Result?\",\n  \"description\": \"A rich result is an enhanced search result shown on search engine results page. Find out how you can achieve a rich result for your page.\",\n  \"publisher\": {\n    \"@type\": \"Organization\",\n    \"@id\": \"https:\/\/www.schemaapp.com\/#Organization\",\n    \"url\": \"https:\/\/www.schemaapp.com\/\",\n    \"name\": \"Schema App\",\n    \"description\": \"Schema App is an end-to-end Schema Markup solution...\", \n    \"telephone\": \"18554448624\",\n    \"email\": \"support@schemaapp.com\",\n    \"areaServed\": \"http:\/\/www.wikidata.org\/entity\/Q13780930\",\n  }\n}\nLinking to external entities\nOur tools also allow SEO teams to link to external entities using a variety of methods such as:\n\nManually linking to external entities using properties like sameAs and additionalType\nAutomatically linking to external entities using our Omni Linked Entity Recognition feature in the Schema App Highlighter tool\nAutomatically linking the categories and tags on a WordPress site to existing Wikipedia and Wikidata entities using our Advanced WordPress plugin.\n\nYou can read this article to learn more about our entity linking methods.\nOvercome the challenges of implementing Linked Data\nIn summary, Linked Data facilitates the connection of data from different sources to provide machines with more contextual information, enabling them to infer new knowledge from existing facts.\nApplying Linked Data through the Schema Markup on your site can help search engines understand the relationship between the entities on your site and disambiguate the entities mentioned in your content.\nIf you need help implementing Linked Data on your site, we can help. At Schema App, we provide SEO teams with the tools and expertise to implement Linked Data at scale.
