A keyword is a word or phrase that people type or speak into a search engine, such as “emergency plumber Croydon” or “how to register for VAT”. In SEO, the term also means the phrase a particular page is chosen to rank for, often called its target or focus keyword.
How keywords work
Strictly, what a person types is a search query, and a keyword is the generalised version a marketer plans around. “Plumber in Croydon open now”, “croydon plumber emergency” and “emergency plumbing Croydon” are different queries, but they share one keyword and one need, so one page should serve them all.
Search engines no longer match pages to queries word for word. Google interprets meaning, synonyms and context, so a page about “boiler repairs” can rank for “fix my boiler”. What still matters is that the page clearly covers the topic behind the keyword and matches the search intent: whether the person wants to learn, compare, buy or find a particular site.
Keywords vary in length and specificity. Short, broad terms such as “accountant” attract many searches with mixed intentions. Longer, specific phrases such as “accountant for landlords in Bristol” attract fewer searches but say much more about the person, and are often called long-tail keywords. Most small businesses win first on the specific end.
Why it matters
Keywords are how you connect what you sell to the words customers actually use, which are often not the words you use internally. A firm might call its service “domestic retrofit assessments” while homeowners search “how to make my house more energy efficient” or “EPC improvements”. Without that translation, a site can be well written and still invisible.
Choosing one primary keyword per page also keeps the site organised. When each page has a clear job, you avoid two pages competing for the same search, you know which page to improve when results dip, and your keyword map shows the gaps where a needed page does not exist yet.
Keywords also differ by place. UK searchers use UK terms: “solicitor” rather than “attorney”, “estate agent” rather than “realtor”, “postcode”, “MOT”, “council tax”. A keyword list borrowed from a US tool or article without checking can point you at phrases British customers rarely type.
Common mistakes
- Chasing the biggest term. A new site targeting “lawyer” alone competes with national firms and directories for a search that is too vague to convert.
- Ignoring intent. Putting a sales page up for a keyword where Google shows guides, or the reverse.
- Repeating the phrase unnaturally. Keyword stuffing makes copy hard to read and can count against a page.
- One page per wording variation. Separate pages for “boiler repair” and “boiler repairs” split signals between near-duplicates.
- Using industry jargon customers do not search. Check the language people actually use before deciding.
How to act on it
Start with your own customers. Write down how they describe their problem when they phone or email, then check those phrases in the search results and in Search Console, which shows the queries already bringing impressions to your site. Look at what ranks for each candidate: the type of page Google rewards tells you the intent.
Pick one primary keyword per page and a few close variations, then use them naturally in the title, the main heading, the opening paragraph and where they genuinely fit. Write for the person first. If you would like this done systematically, with one target term mapped to each page and no overlaps, that is the purpose of my keyword research service.
