Keyword
A keyword in SEO is a word or phrase that people type into search engines, and that a page targets to match a searcher's topic or intent.
Key takeaways
- Keywords are the terms users search and pages target to match intent.
- Always match search intent—informational, navigational, commercial, or transactional.
- Use keywords naturally in key page elements without over-optimizing.
- Group keywords by intent; one page per intent group.
- Avoid keyword stuffing and targeting multiple intents on one page.
Keywords are the foundation of SEO: they connect what people search for with the content you create.
Example
Imagine you run a blog about gardening. A user types "how to grow tomatoes in pots" into Google. That phrase is a keyword. You create a page titled "How to Grow Tomatoes in Pots" and use the keyword naturally in the title, headings, and body. When Google matches the query to your page, you rank for that keyword.
When should I use this?
Use keywords whenever you create or optimize a page for search engines:
- Content creation: Before writing, choose a main keyword that matches the topic and intent.
- On-page optimization: Place the keyword in the title tag, H1, headings, meta description, URL, and body text.
- Keyword research: Identify relevant terms, audience language, and search intent before producing content.
- Page grouping: Group keywords by intent so each page targets one clear topic.
What it is not
Not a magic formula: Keywords alone won't rank a page; content quality and relevance matter more. Not a synonym for search query: A keyword is the term you target; a search query is what a user types. They can differ. Not a single word only: Keywords can be multi-word phrases (e.g., "best coffee shops in Austin"). Not a list to stuff: Repeating a keyword excessively (keyword stuffing) harms rankings.
Quick start
- Brainstorm topics relevant to your audience.
- Use a keyword research tool (e.g., Ahrefs, Semrush, Google Trends) to find terms with search volume.
- Check search intent: Is the user looking to buy, learn, or find a specific site?
- Pick one main keyword per page that matches intent and has reasonable difficulty.
- Place the keyword naturally in the title tag, H1, at least one H2, first 100 words, meta description, URL, and image alt text.
- Write content that satisfies the query fully—don't just repeat the keyword.
Common mistakes
Exact-match obsession: Repeating the same keyword verbatim instead of covering related terms and intent. Ignoring intent: Choosing a keyword only by volume, without checking if the searcher wants information, a product, or a specific page. Multiple intents on one page: Targeting keywords with different intents (e.g., "buy running shoes" and "how to tie running shoes") on the same page. Keyword stuffing: Overusing the keyword in unnatural ways, which can trigger penalties. Neglecting synonyms: Not using related terms and variations that help Google understand the topic.
