What is keyword research?
Keyword research — Identifying the queries an audience uses, estimating their volume and difficulty, and grouping them into pages worth building. The foundation of any content strategy.
Keyword research identifies the queries an audience uses, estimates how much demand sits behind them and how hard they are to win, and groups them into the set of pages worth building. It is demand research, not a list-building exercise.
Every volume figure you will see is modelled rather than measured, and tools routinely disagree by a factor of two. Treat volumes as relative magnitudes, not absolute forecasts. The one genuinely first-party source is Google Search Console, which tells you what your own site is already being shown for — usually the most valuable input available and the most commonly ignored.
Why keyword research matters for your career
Keyword research is the first thing every SEO learns and one of the last things they learn to do well. The difference between junior and senior work is not tool fluency — it is the ability to turn a keyword list into a defensible page architecture with a sized opportunity attached.
Where this sits on the pay curve
Skills with a technical floor and a small practitioner pool command the largest premiums in SEO hiring. Benchmark what that is worth in your market on the salary by location hub, or score yourself against a target role with the skills gap analyzer.
What keyword research involves day to day
- Start from Search Console: queries you already appear for, especially those on page two.
- Expand with tool data, competitor gaps, People Also Ask and community sources where real language lives.
- Cluster by intent and by the page that would serve it, not by lexical similarity.
- Size the opportunity: realistic position, realistic click-through, realistic conversion. A number a stakeholder can be held to.
- Prioritise on expected value against effort, and be willing to discard high-volume terms you cannot win.
How keyword research comes up in interviews
Expect a practical exercise. What separates candidates is what happens after the list: how you cluster, how you size, and how you decide what not to do. Say out loud that volume figures are estimates.
Evidence that lands
- A cluster-to-architecture mapping you produced and the traffic it delivered against forecast.
- A case where you recommended against pursuing high-volume terms and explained why.

Common mistakes
- Treating tool volumes as fact.
- Building one page per keyword instead of one page per intent.
- Producing a list with no prioritisation, which pushes the actual decision back onto the stakeholder.
