nøkkelordet

Nøkkelordet, or "the keyword" in Norwegian, is a word or short phrase that captures the central topic of a text. In linguistic analysis, keywords help describe content; in information retrieval and metadata, they are used to index documents and guide search and discovery.

The term derives from Norwegian nøkkel (key) and ord (word). When a definite article is applied, the form nøkkelordet is used to mean "the keyword" in a given text.

In search engine optimization and content strategy, nøkkelord are selected to signal relevance to search engines and readers. Keyword research involves identifying terms with appropriate intent and search volume, while considering competition, seasonality, and linguistic variations. Techniques such as frequency analysis, TF-IDF, and keyword clustering are often used to prioritize nøkkelord for content creation and tagging.

Examples include klimaforandringer (climate change), utslipp (emissions), fornybar energi (renewable energy).
