A head keyword is a short, broad search term, usually one or two words such as “accountant”, “boilers” or “wedding venues”, that a large number of people search for with many different needs in mind. Head keywords sit at the opposite end of the scale from long-tail keywords, which are longer, more specific searches made by fewer people with a clearer purpose.
How head keywords work
Picture all the searches in a market arranged by how often they are made. A small number of short, general terms account for a large share of the searches; these are the head. Behind them stretches a very long line of more specific searches, each made less often; that is the tail. Together the specific searches usually add up to far more traffic than the head terms, which is why the long-tail keyword is such a common focus.
Head keywords have three characteristics that follow from being short. They attract high demand, because they are what people type first. They are ambiguous, because one or two words cannot say much about what the searcher wants. Someone searching “solicitor” might want a definition, a local firm, a price or a complaint procedure. And they are fiercely contested, because every business in the sector wants them, so their keyword difficulty tends to be high.
Google handles the ambiguity by mixing result types. A search for “boilers” in the UK may show shopping results, manufacturers, comparison sites, a map of local installers and guides, all on one page. That mix tells you the search intent is split.
Why it matters
For most UK small businesses, head keywords are the wrong place to start. A Sheffield plumber searching for “plumber” will see a map of local businesses, directories and national firms, and the people typing that word want anything from a quote to a DIY fix. “Emergency plumber Sheffield” or “boiler repair Sheffield” are smaller searches but far more likely to turn into a call.
Head keywords still matter in two ways. First, they describe what your business is, so your home page and main category or service pages should be clearly about them. Second, they are the starting point for research: you begin with the head term as a seed keyword and expand into the specific searches beneath it.
Larger sites, such as national retailers, comparison services and established publishers, can and do compete for head terms, usually after years of building authority on the specific searches first.
Common mistakes
- Judging success by one head term. Owners often check only their position for “accountant London”, while their real enquiries come from dozens of specific searches.
- Targeting the head term on every page. This causes keyword cannibalisation, where several pages compete and none ranks well.
- Ignoring the mixed intent. Building a sales page for a term where Google mostly shows guides, or the reverse.
- Chasing volume over fit. A popular term that brings the wrong visitors costs time and, in paid search, money.
How to act on it
Write down the head terms that describe your business and search each one in Google from a UK location. Note what types of result appear and who ranks. If the first page is all national brands and directories, treat the term as a long-term aim rather than a near-term target.
Make sure one clear page owns each head term, usually your home page or a main service or category page, and that it covers the subject well. Then expand each head term into the specific services, locations, problems and questions beneath it, and map each of those to its own page.
Turning a handful of broad terms into a structured map of winnable searches is exactly what keyword research is for.
