Search intent is a long-established framework. Below are the standard definitions, the on-page signals each type tends to use, and authoritative references to back them up.
Informational
The visitor wants to learn or understand something. They're not buying yet, they're researching. Examples: "how does HSTS work", "what is dropshipping", "best practices for API design".
On-page signals: Article / BlogPosting / HowTo / FAQ schema, "how to" / "what is" / "guide" titles, /blog/ or /docs/ URL paths, byline + publication date.

Commercial Investigation
The visitor is comparing options before they buy. They've decided they want a thing — now they're picking which one. Examples: "best CRM for small business 2026", "Notion vs Obsidian", "Stripe alternatives".
On-page signals: Review / AggregateRating schema, "best X" / "X vs Y" / "top N" / "reviews" titles, /reviews/ or /comparisons/ URLs, comparison tables.

Transactional
The visitor is ready to take action. Buy, sign up, book, download, subscribe. Examples: "buy Sony WH-1000XM5", "Notion pricing", "rent car SFO airport".
On-page signals: Product / Offer / SoftwareApplication schema, visible price ($/€/£), "Buy now" / "Add to cart" CTAs, /products/ or /pricing/ or /checkout/ URLs.

Navigational
The visitor knows the brand or page they want. They're using search to navigate, not discover. Examples: "facebook login", "anthropic careers", "stripe docs".
On-page signals: Organization / AboutPage / ContactPage schema, brand name in title/H1, conventional URLs (/, /about, /contact, /careers).
