Keyword

A keyword is a specific word or phrase that a person enters into a search engine, as well as the phrase a webpage is written to target.

also called: keywords

// definition

In Search Engine Optimization (SEO), a keyword is a core text term or phrase that encapsulates the primary topic of a digital document and matches what users submit to search engines. Keywords consist of individual words, compound terms, or complete phrases that content creators intentionally incorporate into page elements such as headings, body text, and metadata. Search engines evaluate these terms to index pages and determine relevancy when retrieving results for user requests.

A keyword is frequently confused with a search query. While a keyword is an abstracted phrase targeted by content creators, a search query is the exact string of characters typed by an individual user, which may include typos, variations, or unique phrasing.

// why it matters

Identifying and targeting the terms prospective customers use allows a business to align its web content with actual market demand. When a website structures its pages around relevant terms, search engine crawlers accurately index the content for corresponding searches. This alignment increases visibility in search results without requiring paid advertising spend. Conversely, targeting incorrect terms or omitting primary industry terminology results in search engines failing to present the business to qualified users, leading to missed organic market reach and diminished online revenue potential.

// example

A commercial enterprise selling enterprise accounting software targets the keyword "cloud accounting platform" on its main product page. The writers place this exact phrase in the title tag, main heading, and introduction. When an individual submits a search using that phrase, search engines recognize the direct thematic match between the user input and the webpage content, returning the product page in the search engine results page.

Questions and Answers

What is the difference between a keyword and a search query?
A keyword is a standardized phrase targeted by a marketer to capture search traffic, whereas a search query is the exact text entered by a user. While a keyword might be "accounting software," user search queries could include misspellings, specific questions, or added regional locations referencing that core keyword.
How many keywords should a single webpage target?
A single webpage typically targets one primary keyword alongside a small group of closely related secondary terms. Focusing on one central concept ensures the page maintains clear topic relevance for search engine crawlers without diluting the content or confusing readers with unrelated subjects.
Is keyword density still important for SEO?
Keyword density, or repeating a term a specific percentage of times, is no longer a primary ranking factor. Modern search engines evaluate natural context, semantic relationships, and user intent rather than strict repetition, meaning artificially forcing terms into text can harm readability and performance.
