Seed Keyword
The broadest term you start from, used to expand into hundreds of narrower phrases inside a research tool.
Analogy Mental model
A seed. From coffee you can grow roast level, pour-over technique, cold brew caffeine content and a hundred branches nobody planned.
In practice What you actually do
Sit with sales and product for an hour and write down five to ten nouns describing what the business actually sells, not what marketing calls it. Put those into Ahrefs or Semrush and expand in bulk, then keep the list in a document so next quarter's research starts from the same vocabulary instead of a new guess.
Where people get burned Pitfalls
Too narrow and the vocabulary runs dry after twenty phrases. Too wide, software for example, and you get a hundred thousand irrelevant terms that cost more to filter than they return.
