# Keyword

> A keyword is a word or phrase users type into a search engine and around which page content is optimised so it answers their query.

A **keyword** is a word or phrase that users type into a search engine and around which page content is optimised so it best answers their query. It is the foundation of [SEO](https://nodea.io/en/glossary/seo) and paid campaigns: it defines which queries a site should be visible for. Well-chosen keywords connect what an audience is searching for with what a page actually offers.

## How keyword selection works

Keywords are grouped by length and intent, which shapes how they are used:

- **[Short tail](https://nodea.io/en/glossary/short-tail-keywords) terms** — short, broad, high-traffic and highly competitive.
- **[Long tail](https://nodea.io/en/glossary/long-tail) terms** — longer, precise, lower in volume but higher in conversion.
- **Intent** — informational, navigational, commercial or transactional; it indicates which type of content satisfies the query.

The key is matching content to [search intent](https://nodea.io/en/glossary/search-intent) — a sales page will not answer an informational query, and vice versa.

## Keywords in practice

Keyword research kicks off almost every SEO and content marketing project. It underpins a topic map, informs site structure, assigns terms to specific pages and drives content that answers real queries. Keywords are used in titles, headings and body text — always naturally, without stuffing. Tools such as a [keyword planner](https://nodea.io/en/glossary/keyword-planner) support the selection, while ongoing rank tracking lets you expand the strategy with new, valuable queries.

### How do I choose the right keywords?

Start by analysing your audience's queries and their intent, then weigh search volume, competition and fit with your offer. Tools such as a keyword planner, Search Console data and the phrases your site already ranks for all help.

### How many keywords should a page target?

There is no fixed number. One page should target a single main topic and intent, surrounded by naturally related terms. What matters more than count is avoiding keyword stuffing and writing content primarily for the user.
