The short answer

Start with seed topics from your business, then expand them into keyword ideas using tools. Seed keywords are the broad starting terms you grow from. Expand them with Google Keyword Planner, Search Console, autocomplete and related searches. Choose targets by weighing demand against difficulty and matching intent. Research is ongoing, revisited as demand shifts, never truly finished.

Broad to focused

The overall process, and where you start

You do keyword research by starting with seed topics from your business, expanding them into keyword ideas using tools, then assessing each for demand, intent and difficulty before choosing what to target. It moves from broad to focused; because you filter as you go, you end with a shortlist worth pursuing, which builds on what keyword research is. Seed keywords are the broad starting terms that describe your business or topics, which you then expand into longer, more specific keywords. They are the seeds you grow from; because they set the direction, good seeds lead to a richer keyword list.

Expanding, choosing and timing

How to expand, how to choose, and why it never really ends

You expand seed keywords using tools like Google Keyword Planner and Search Console, autocomplete suggestions, and related searches, which surface variations and questions. Tools multiply your ideas; because they draw on real searches, they reveal terms you would not think of, including question keywords. You choose which keywords to target by weighing demand against difficulty and matching intent to what you offer, favouring realistic terms you can genuinely serve. It is a balance; because chasing only high-volume terms rarely works, a mix that fits your site is wiser, often built from low competition keywords. A focused round can take a few hours, but research is ongoing as you learn what works and demand shifts, so it is never truly finished. It is a habit, not a one-off; because search changes, revisiting your keywords keeps content aligned.
