# Keyword Intent Taxonomy

A comprehensive classification system for understanding search intent, mapping keywords to content strategies, and aligning with conversion funnels.

## Overview

Search intent (also called user intent or query intent) is the underlying goal a user has when typing a query into a search engine or AI system. Correctly classifying intent determines content format, tone, depth, and conversion strategy.

This taxonomy defines **4 primary intent types**, each with **3-4 sub-categories**, along with signal words, SERP feature correlations, and content format recommendations.

## Mixed Intent Queries

Many real-world queries blend multiple intent types. Recognize and address the dominant + secondary intent.

### Common Mixed Intent Patterns

| Query Pattern | Primary Intent | Secondary Intent | Content Strategy |
|--------------|---------------|-----------------|-----------------|
| "best [product] for [use case]" | Commercial | Informational | Buying guide with educational context |
| "how to [task] with [product]" | Instructional | Navigational | Tutorial featuring the product |
| "[product] review and pricing" | Commercial | Transactional | Review with clear pricing CTAs |
| "what is [concept] tools" | Informational | Commercial | Explainer that transitions to tool recommendations |
| "[product] free download" | Transactional | Navigational | Landing page with download + product info |

### Handling Mixed Intent in Content

1. **Lead with the primary intent** -- answer the dominant question first
2. **Bridge to the secondary intent** -- naturally transition to the secondary need
3. **Match SERP format** -- if SERPs show mixed results, your content should too
4. **Segment CTAs** -- provide different CTAs for different intent segments within the page

## Applying Intent Taxonomy in Keyword Research

### Step-by-Step Classification Process

1. **Read the query literally** -- what is the user asking for?
2. **Check for signal words** -- match against the signal word tables above
3. **Verify against SERP** -- what does Google actually show? The SERP is the ground truth
4. **Identify sub-category** -- narrow from primary intent to sub-category
5. **Check for mixed intent** -- does the query blend two types?
6. **Map to content format** -- select format based on intent + sub-category
7. **Assign funnel stage** -- determine where this fits in the buyer journey
8. **Set conversion expectation** -- align CTA and goals with intent type

### Common Classification Mistakes

| Mistake | Example | Why It's Wrong | Correct Classification |
|---------|---------|---------------|----------------------|
| Treating all "best" queries as informational | "best CRM software" | User is comparing products to buy | Commercial Investigation |
| Treating all questions as informational | "how much does Ahrefs cost" | User is evaluating a purchase | Commercial / Transactional |
| Ignoring local intent | "SEO services" | May have strong local intent in many contexts | Transactional (local) |
| Missing navigational intent | "HubSpot blog" | User wants a specific page | Navigational |
| Assuming single intent | "SEO tools" | Could be informational OR commercial | Mixed -- check SERP |
