Entity Linking: The Decision Tree for Every Link in Every Article

Entity Linking is the practice of connecting every mention of a person, business, concept, or organization in your content to the most authoritative source about that entity. At BlitzMetrics, entity linking follows a specific decision tree that determines where each link should point — because linking to the wrong destination confuses Google about who owns the topic and can actively hurt your rankings.

Entity linking is not the same as regular hyperlinking. A regular hyperlink says “here is more information.” An entity link says “this is the authoritative source for this entity according to Google’s Knowledge Graph.” The difference matters because Google uses links to understand relationships between entities. When you link a person’s name to their personal brand site, you are telling Google that this person and this site are the same entity. When you link a BlitzMetrics concept to its definitive article, you are reinforcing the SEO Tree that gives that article topical authority.

The Entity Linking Decision Tree

Every time you mention an entity in a BlitzMetrics article, follow this decision tree to determine the correct link destination.

Is it a person?

If the entity is a person, link to their personal brand website — the domain that matches their name. For Dennis Yu, that is dennisyu.com. For a client whose site we built (like Ibrahim Awad), link to their personal brand domain. Never link a person’s name to their social media profile, their LinkedIn, or a BlitzMetrics article about them. The personal brand site is the canonical entity reference — Google uses it to anchor everything else it knows about that person.

Is it a business or organization in our network?

If the entity is a business, agency, or organization that we work with or that is part of the BlitzMetrics network, link to their primary website. For example, ChurchCandy links to their website, not to the BlitzMetrics case study about them. The case study is about them — their website IS them. Google needs to see the link pointing to the entity, not to a page discussing the entity.

Is it a BlitzMetrics concept?

If the entity is a BlitzMetrics concept or methodology — Content Factory, Dollar a Day, Digital Plumbing, Nine Triangles, MAA, Knowledge Panel — link to its definitive article on blitzmetrics.com. This is the whole point of the definitive article architecture. One page per concept, and every mention links back to it.

Is it an external concept or well-known entity?

If the entity is an external concept (like Google Analytics, Facebook, or E-E-A-T) or a well-known entity not in our network, link to the most authoritative source. For Google products, link to the official Google page. For industry concepts, link to the most authoritative industry source. For public figures, link to their personal website or official page. Do not link to Wikipedia unless no better source exists — Wikipedia links pass minimal value and signal that you do not have a deeper relationship with the entity.

Why Entity Linking Matters for SEO

Google’s algorithm has moved from keyword matching to entity understanding. When Google reads a page, it does not just count how many times “content factory” appears — it tries to understand what entity the page is about and how it relates to other entities. Entity linking is how you teach Google these relationships explicitly.

Every internal link to a definitive article reinforces that article’s authority on its topic. Every outbound link to a person’s brand site reinforces the entity connection between BlitzMetrics and that person. Every link to an external authority signals that your content participates in the broader knowledge graph for that topic. Done correctly, entity linking turns every article you publish into a node in a network that makes every other node stronger — which is exactly how the SEO Tree works.

Done incorrectly — linking to random pages, social profiles, or articles that compete with the definitive article — you create the content vandalism problem that dilutes your authority instead of building it.

Entity Linking in Practice

The Blog Posting Guidelines require entity linking on every article published on blitzmetrics.com. The Meta-Article Prompt includes entity linking instructions so that AI agents producing content apply the decision tree automatically.

Here is what correct entity linking looks like in a typical BlitzMetrics article. When the article mentions Dennis Yu, the link points to dennisyu.com. When it mentions the Content Factory, the link points to blitzmetrics.com/content-factory/. When it mentions a client like Brady Sticker, the link points to his personal brand site or ChurchCandy’s website. When it mentions Google Analytics, the link points to Google’s official GA4 page. Every link has a specific, intentional destination based on the decision tree.

Common Entity Linking Mistakes

The most frequent mistakes BlitzMetrics editors catch during QA — whether in article reviews or the full website QA audit — include linking a person’s name to their LinkedIn profile instead of their personal brand site, linking a BlitzMetrics concept to a case study or blog post instead of the definitive article, linking to a competing article about a topic when a definitive article already exists on blitzmetrics.com, using bare URLs instead of descriptive anchor text, and over-linking the same entity multiple times in one paragraph. The rule of thumb is to link each entity on its first meaningful mention in the article and then not again unless the article is very long and the repeated mention appears in a different section.

How Entity Linking Connects to Other Concepts

SEO Tree — Entity linking is the mechanism that builds the tree. Each link is a branch connecting a leaf (article) to its trunk (definitive article).

Definitive Articles — The entire definitive article architecture depends on entity linking to work. Without correct links, the architecture has no connective tissue.

Blog Posting Guidelines — Entity linking is a required step in the blog posting checklist.

Knowledge Graph and Entities — Entity linking is how you feed Google’s Knowledge Graph the relationship data it needs to rank your content.

Knowledge Panel — Consistent entity linking across the web is one of the signals Google uses to generate Knowledge Panels.

Website QA Audit — The website QA audit checks entity linking compliance as part of its Content Architecture layer. Every personal brand site is audited to verify that internal links follow this decision tree before launch.
