Hubspot AI Semantics Guide

Hubspot demonstrated how a few strategic semantic SEO improvements can dramatically increase AI citations, helping content surface more often across search results and large language models.

This how-to guide distills the approach from the original Hubspot experiment into practical steps you can apply to your own site, showing how to speak the same language as search engines and AI systems.

Why Semantics Matter for Hubspot and AI

Modern search engines and AI tools don't only match keywords; they understand entities, relationships, and context.

When Hubspot refined its semantic structure, AI systems could more easily recognize:

• What each page was about
• Which entities were central to a topic
• How pages related to each other
• Why a page was a good answer to a query

This shift from keywords to meaning is what powered their jump in AI citations.

Hubspot Semantic Strategy Overview

The core of the Hubspot approach is systematic semantic clarity rather than chasing individual keywords. That means:

• Defining entities and topics precisely
• Structuring content for machines and humans
• Using consistent language and naming
• Reinforcing relationships across pages

The original experiment, described in detail on the Hubspot marketing blog, showed how this can unlock hundreds of new AI citations.

Step 1: Map Your Core Entities Like Hubspot

Start by identifying and organizing the entities that matter most to your business, just as Hubspot did for its content library.

List Primary Business Entities

Make a clear list of high-value entities that define your brand and offerings:

• Brand entities (company name, major products)
• Service entities (solutions, methodologies, frameworks)
• Audience entities (roles, industries, business sizes)
• Topic entities (key themes your content covers)

Each of these should have a clearly defined meaning and a consistent label.

Group Entities Into Semantic Clusters

Create clusters where each group of entities revolves around a central topic, similar to how Hubspot organizes marketing, sales, and service content.

• Choose one "pillar" entity per topic cluster
• Assign related "subtopic" entities beneath it
• Ensure every piece of content belongs to a specific cluster

This structure helps search engines and AI understand what is most important on your site.

Step 2: Restructure Content for Semantic Clarity

Hubspot made content easier for AI to parse by aligning language, headings, and internal links with its entity model.

Standardize Terminology Across Pages

Use one consistent term for each major entity instead of many variations.

• Pick a canonical name (e.g., “marketing automation platform”)
• Avoid unnecessary synonyms that dilute the entity signal
• Update legacy content to follow the new standard

Consistency makes it easier for AI tools to recognize that different pages refer to the same thing.

Align Headings With Entity Structure

Follow the Hubspot style of using headings to clearly introduce topics and subtopics.

• Use H2 tags for pillar topics and primary entities
• Use H3 tags for subtopics, features, or use cases
• Include clear, descriptive phrases in headings instead of vague labels

This creates a machine-readable outline of your content.

Step 3: Strengthen Internal Linking Like Hubspot

Hubspot increased AI visibility by making relationships between pages obvious through structured internal linking.

Create a Pillar–Cluster Link Framework

For each topic cluster:

1. Link every supporting article back to the pillar page with descriptive anchor text
2. Link from the pillar page to each high-value supporting page
3. Use anchors that mention the relevant entity or topic clearly

This reinforces topical authority and shows AI systems which pages best represent a topic.

Use Internal Links to Clarify Meaning

Beyond navigation, links can disambiguate entities.

• Link brand mentions to an "About" or core brand page
• Link product mentions to a single canonical product page
• Link concept mentions to a definitive educational page

A targeted approach, similar to what Hubspot uses, trains AI systems on which page is the "source of truth" for an idea.

Step 4: Optimize for LLM-Friendly Structure

Large language models prioritize content that is easy to extract, summarize, and cite. Hubspot tailored its structure so AI tools can lift clean, self-contained answers.

Write Self-Contained Answer Blocks

For each key question or intent:

• Start with a direct, one- or two-sentence answer
• Follow with short supporting paragraphs
• Use bullet points or numbered steps where possible

This format helps AI systems quote your content as a concise answer.

Use Descriptive, Intent-Focused Subheadings

Design subheadings that mirror common user questions.

• Include action verbs (e.g., “How to set up…”, “When to use…”)
• Reflect real search queries where appropriate
• Group related instructions under a single H2 or H3

The more your structure matches user intent, the easier it is for AI to match your content to a prompt.

Step 5: Measure AI Citations Like Hubspot

To understand whether your changes work, follow an approach similar to the Hubspot experiment in tracking AI citations over time.

Track Mentions Across Search and AI Tools

Monitor:

• Presence in AI-generated overviews and answer boxes
• Appearance in conversational AI responses for target queries
• References to your brand or URLs in AI-powered search features

Compare baseline data with post-implementation performance to quantify impact.

Iterate on Semantic Signals

Use performance data to refine your structure.

• Strengthen successful clusters with new supporting content
• Clarify underperforming topics with more explicit headings
• Adjust internal links to emphasize the best-performing pillar pages

This feedback loop is central to how Hubspot scaled semantic gains across its content ecosystem.

Applying the Hubspot Model to Your Site

You don't need the scale of Hubspot to benefit from semantic optimization. Any site can adopt these principles:

• Define a clear entity model
• Standardize terminology everywhere
• Structure content by topics and intent
• Use purposeful internal links
• Monitor AI and search behavior continuously
