Term

Query types (informational, transactional, navigational, commercial)

Query types classify search queries by user intent. Four common classes — informational, navigational, transactional, commercial investigation — decide which content type ranks.

Query types — explained in more detail

The classic three-class taxonomy (Broder 2002) — informational, navigational, transactional — has been extended in marketing usage by a fourth class, commercial investigation:

  • Informational: knowledge question (“what is crawl budget?”, “how does hreflang work?”). Answer-style content ranks: glossary, guides, blog.
  • Navigational: search for a specific brand or site (“Anthropic login”, “GitHub”). The brand’s own page is the optimal hit.
  • Transactional: action with purchase/conversion intent (“buy Astro hosting”, “convert PDF”). Product or tool page ranks.
  • Commercial investigation: preparing a buying decision (“best vector database”, “Claude vs GPT”). Comparison and review content ranks.

Mismatched intent is a common ranking killer: a category text on a product page, generic FAQ instead of guide depth — Google ranks where intent and content type align.

Example / In practice

Keyword “SEO agency Berlin” — commercial/transactional intent. A 3,000-word “what is SEO” guide will not rank because searchers expect a provider page with services, references, contact. Conversely, an offer landing page won’t rank for “what is SEO” — wrong intent.

Distinction from similar terms

Search intent is the umbrella term; query types are the concrete classification. Long-tail keywords sit on a length/specificity axis, orthogonal to intent. SERP features are the consequence of different intents (featured snippets for informational, shopping for transactional).
