What is keyword research?

Keyword research: definition and meaning

A keyword is a search term or search phrase, such as “heat pump grants” or “tax advisor for skilled trades businesses.” Research clarifies how customers actually phrase their needs—often differently from the technical vocabulary used inside the company. If you only write “interior fit-out” in your menu, you may not be found for “custom built-in wardrobe.”

Research is the foundation of every SEO strategy, but it also helps with Google Ads campaigns, site structure, and content planning. It also shows which questions prospects ask before they request a quote. The result is a topic list that editorial, sales, and tech teams can work through together.

How the research works

The starting point is seed keywords drawn from services, products, and customer questions. Related terms come from Google Keyword Planner, Google Trends, search autocomplete, Search Console, or tools such as Sistrix and Semrush. It is also worth looking at the results page itself: question boxes and “related searches” show which topics Google associates with the term. The terms are then evaluated:

• Search volume: estimated monthly queries—a guide, not an exact figure
• Competition: how strong are the pages that already rank?
• Search intent: does the user want to learn, compare, or buy?
• Relevance: does the term genuinely fit your own offer?
• Long tail: longer, more specific phrases with less competition

Real-world example: a carpentry shop plans its pages

A carpentry shop describes its services as “interior fit-out” and “furniture making.” Research shows that customers search more often for “custom built-in wardrobe,” “wardrobe for sloped ceiling,” or “kitchen from a carpenter.” The shop creates one page for each of the most important needs and assigns each keyword to exactly one page. That way its own pages do not compete with each other (keyword cannibalization).

After a few months, Search Console shows which further terms already bring visitors, and the plan can be expanded in a targeted way. Frequent questions from customer service, such as those about delivery times or installation, also supply ideas for new guide pages. This feedback lets you keep refining the topic plan.

Benefits, limitations, and common mistakes

Keyword research replaces gut feeling with data and makes content plannable. Limitations: search volumes are estimates, Keyword Planner often shows only ranges without running ads, and many valuable queries have only a few searches per month. In addition, users increasingly put whole questions to AI assistants, which classic tools barely capture. Weighting matters too: a term with few searches but high purchase intent is often more valuable to a business than a popular informational term.

• Chasing only terms with high search volume
• Ignoring search intent and offering product pages for purely informational searches
• Optimizing several pages for the same keyword
• Using technical jargon instead of customer language
• Doing the research once and never updating it

What companies should look out for

Talk to sales and customer service: that is where the questions and objections of real customers are best known. Group keywords into topics, prioritize by business value rather than volume alone, and review the results regularly.
