A seed keyword is a short, broad starting term, usually one to three words, that you feed into keyword research to generate a longer list of related searches. For a bathroom fitter, seeds might be “bathroom fitting”, “wet room” and “bathroom renovation”.
How seed keywords work
Keyword tools expand a seed in several ways. They find longer phrases that contain it (“wet room installation cost”, “wet room for elderly parent”), questions people ask about it, related terms that bring up similar results, and terms that competing sites rank for. A handful of good seeds can produce thousands of ideas, which are then filtered, grouped and mapped to pages.
Seeds are not usually targets in their own right. Many are head keywords: broad, competitive and vague about what the searcher wants. Their job is to open up the long-tail terms beneath them, which are more specific and often more realistic to win.
The output is only as good as the seeds. Start only from the words your business uses internally and the research will miss how customers describe their problem. A heating engineer who seeds only “boiler installation” may never see “combi boiler replacement”, “no hot water”, “boiler grant” or “heat pump installer”.
It helps to think of seeds in a few kinds. Service or product seeds name what you sell (“loft conversion”). Problem seeds name what the customer is facing (“not enough bedrooms”, “loft too cold”). Audience seeds name who is searching (“landlord”, “first-time buyer”). Place seeds add the areas you serve (“Croydon”, “Surrey”). Combining the kinds is often where the most useful long phrases turn up.
Why it matters
Seeds set the boundaries for everything that follows. Miss a seed and you miss a whole branch of demand; choose one that is too broad and you bring in noise that takes hours to sort. Good seeds also reflect the UK market. Customers here search for a “solicitor” rather than an “attorney”, a “postcode” rather than a “zip code”, a “flat” as often as an “apartment”, and “VAT” when buying for a business.
For a small business, a well-chosen seed list keeps the research focused on what you actually sell and where you sell it. For a larger site, separate seed lists for each product line or service area make it much easier to see where the gaps are.
Common mistakes
- Starting from one seed and assuming the tool will find everything else.
- Using only trade jargon, brand names or product codes.
- Seeds so broad (“marketing”, “insurance”) that they flood the list with irrelevant terms.
- Forgetting problem-based seeds. People often search for the symptom (“damp patch on ceiling”) rather than the service (“roof repair”).
- Running seeds against a US database and getting American vocabulary back.
How to act on it
Build your seed list from several sources: your services and products; the words customers use in enquiries, calls and reviews; the queries already in Google Search Console; Google’s autocomplete and “People also ask”; and the menus of competing sites. A quick competitor analysis often reveals whole topics you had not considered.
Aim for a list that covers every service, every customer problem and every type of customer, with each tool set to the United Kingdom. Expand each seed, remove anything irrelevant, then group what remains by intent and assign each group to one page through keyword mapping. Taking a business from the first seed to a finished page plan is what my keyword research service covers.
