Keyword Research and Search Intent

Keyword research is often described as "finding words people search for," which is true but incomplete enough to be misleading. The harder and more valuable part is figuring out search intent - what the searcher is actually trying to accomplish behind that query - because a page can rank for exactly the keyword it targeted and still fail, if it answers a different intent than the one the searcher had.

Search Intent Comes in a Few Recognisable Shapes

Most queries fall into one of four broad intents, and recognising which one a keyword represents should happen before any content gets written:

• Informational - the searcher wants to understand something ("what is technical SEO," "how does Core Web Vitals affect rankings"). They're not ready to buy yet, and a page that pushes a hard sell here usually underperforms a page that actually answers the question well.
• Navigational - the searcher already knows where they want to go and is using search as a shortcut ("Ahrefs login," "Screaming Frog download"). There's little point competing here unless it's your own brand term.
• Commercial investigation - the searcher is comparing options before deciding ("best SEO tools for small teams," "Ahrefs vs Semrush"). This is where comparison content and detailed feature breakdowns earn their keep.
• Transactional - the searcher is ready to act ("SEO audit service," "hire technical SEO consultant"). This is where service and product pages should be targeted, not blog posts.

The practical test for intent is simple: look at what's currently ranking for the keyword. If the top results are all blog-style explainers, the intent is informational and a service page probably won't outrank them regardless of how well it's optimised. If the top results are comparison articles or tool roundups, that's commercial investigation, and a straightforward product page is fighting the wrong format.

Why Matching the Wrong Intent Wastes the Whole Effort

A page built around the right keyword but the wrong intent can still rank reasonably well, especially for lower-competition terms, and still convert almost nobody. Someone searching "what is off-page SEO" wants a clear explanation, not a pitch - land them on a page that opens with a sales pitch and they bounce immediately, which is also a signal search engines pick up on over time. The reverse is just as costly: someone actively comparing SEO agencies and ready to reach out gets a generic definitional page instead of the specific reasons to choose one option over another, and the page never converts a genuinely warm visitor.

This is also where research tools like Ahrefs, Semrush, and Screaming Frog earn their cost - not just for volume numbers, but for surfacing what's actually ranking for a term today, which is the fastest way to confirm intent before committing to a content format. For a practical walkthrough of running this research in one of those tools, see how to use Semrush for keyword research.

Volume Is a Secondary Filter, Not the Starting Point

Search volume tells you how many people are asking a question, not whether they're the right people or whether your site has a realistic shot at ranking for it. A term with modest volume but clear commercial intent and low competition is usually worth more than a high-volume informational term dominated by sites with far more authority. Prioritise by a combination of intent match, realistic ranking difficulty given your site's current authority, and business relevance - volume is the filter that comes after those, to break ties between similarly good options, not the filter that decides what to target first.

One Keyword Family Per Page

A single page should target one primary keyword and its close variants, not a spread of loosely related terms. Trying to rank one page for several genuinely different intents at once - informational and transactional together, for instance - usually means the content, structure, and calls to action end up compromised for all of them rather than well-matched to any. Where multiple intents genuinely exist around a topic, that's a signal to build multiple pages, each matched to one intent, and link them together rather than forcing one page to do every job.
