keyword

basicwidespread

A keyword is the word or short phrase that indicates the topic of a search: in everyday usage, it is what you type into the search engine; in marketing, it is what websites and advertisers aim to appear for.

In plain terms

A keyword is like a subject heading in a library catalog: not the full content of the book, but the label by which you find it. When you type 'cheap winter tires' into a search engine, these three words are the keywords, and the search engine looks for pages about them.

The term is used from two sides. For you, the searcher, it is what you type in. For the website owner and the marketer, it is the term they want their page or advertisement to appear for, so they adjust their text and ads accordingly.

AI-based search redraws this picture. Instead of typing two or three words to the chatbot or AI agent, you ask a full-sentence question, and the system tries to understand the meaning rather than focusing on exact word matches. Keywords do not disappear, but increasingly serve as indicators of topic and intent rather than magic words.

How it works

The search engine continuously crawls websites and builds a massive index of which words and topics appear on which pages.
When you enter a keyword, the system tries to guess your intent: whether you want to gather information, buy something, or find a specific page.
It selects pages relevant to the topic from the index and ranks them based on content quality, reliability, and many other factors.
Ads also appear alongside search results. Advertisers specify in advance which keywords they want to target. A fast, automated auction decides who gets the spot, where not only the offered bid matters, but also how good and relevant the ad is to the search.
Modern search engines and AI responders recognize synonyms and paraphrases, so a page may appear even if the exact entered phrase does not appear in it.

An everyday example

Your washing machine breaks down, and you type into the search engine: "washing machine repairman Győr weekend". At the top of the list are ads marked "sponsored" from repairmen who advertise for these or similar keywords and pay per click. Below them follow the pages that the search engine deemed the best results.

A common misconception

MythThe more often a keyword appears on the page, the higher it ranks in the search results.

In realitySearch engines have long recognized and penalized keyword stuffing. Today, what matters is whether the page truly provides a good answer to what the user wants to know.

Limits and risks

The same keyword can cover multiple intents: someone typing "jaguar" might be searching for an animal or a car.
The figures given for search volume are estimates, vary by tool, and can be particularly inaccurate in the Hungarian market because of the small numbers involved.
Competition for popular keywords is fierce, and the cost of advertising clicks can quickly skyrocket for these.
AI summaries answer many questions directly on the search results page, so a good ranking does not necessarily bring visitors to your site.

Similar, but not the same

search query – The query is what the user actually types, while the keyword is the term a marketer targets; the two do not always coincide.
hashtag – A hashtag is a label starting with the # symbol that the author adds to a social media post so it can be clicked or searched. A keyword does not need such marking, as it is the term typed into a search engine or targeted by a marketer.
prompt – A prompt is an instruction or question given to an AI system, often in several sentences. A keyword is typically just a few-word search query.

A brief history

The keyword concept moved from library subject indexing and computer information retrieval to the world of web search engines. Keyword bidding, pay-per-click search advertising, was introduced by GoTo.com (later Overture) in 1998. Google launched its AdWords advertising system in 2000, which now operates as Google Ads. These made the keyword a fundamental concept in search marketing.

Where things stand

By the end of 2026, the keyword remains the basic unit of search engine optimization and search advertising. However, due to AI summaries and conversational search, the focus is shifting from exact word matches to topics, search intent, and full-sentence questions.
