Keyword Research: Finding Terms You Can Actually Rank For

How to judge whether you can realistically rank for a term, why search intent decides your content format, and how to group keywords into clusters.

Keyword research answers two questions: what do people search for, and which of those terms can you realistically compete for. Most keyword research fails on the second question — producing long lists of high-volume terms the site has no chance of ranking for.

Search intent decides everything

Before volume or difficulty, work out what someone wants when they type a query. Google ranks pages that satisfy intent; if your format is wrong, no amount of optimisation rescues it.

IntentExample queryWhat ranksConverts?
Informationalwhat is schema markupGuides, definitions, tutorialsRarely — builds awareness
Commercialbest seo tools for agenciesComparisons, listicles, reviewsWell — high purchase intent
Transactionalbuy ahrefs subscriptionProduct and pricing pagesBest
Navigationalflux n pro loginThe specific page requestedN/A — existing users

The reliable way to identify intent is to search the term and look at what already ranks. If the first page is entirely tutorials, Google has decided that query is informational. Publishing a product page against it will not work, however good the page is.

Reading the metrics honestly

Search volume

An estimated monthly average, not a measurement. Every tool models it differently, which is why the same keyword shows different volumes in different tools. Treat it as an order of magnitude — the difference between 100 and 10,000 is meaningful; the difference between 480 and 520 is noise.

Volume also hides seasonality. A term averaging 1,000 a month might be 8,000 in November and 50 in June.

Keyword difficulty

A 0–100 estimate of how hard ranking on page one would be, usually derived from the backlink profiles of pages currently ranking. It is a useful filter and a poor oracle — it typically ignores content quality, topical authority and how well existing results match intent.

DifficultyRealistic forNotes
0–20Brand-new sitesLong-tail, specific, low competition
20–40Sites with some authority and contentThe productive middle ground for most
40–60Established sites in the nicheNeeds genuinely strong content plus links
60+Major authority sitesLong-term targets, not quarterly ones

Judge difficulty against yourself

Difficulty is relative to your site, which is why a universal score misleads. Always open the actual results page and ask whether your site plausibly belongs among those ten. That check beats any number.

Long-tail keywords

Long-tail keywords are longer, more specific queries with lower individual volume. "Project management software" is a head term; "project management software for small construction teams" is long-tail.

  • Far less competition, so a new site can actually rank.
  • Much clearer intent, which usually means better conversion.
  • They accumulate — fifty terms at 40 searches a month outperform one term at 2,000 you never reach.
  • Ranking for specific terms builds the topical authority you need before head terms become realistic.

For most sites the correct strategy is to win long-tail terms first and treat head terms as something you earn later, not something you chase now.

Where to find keywords

  1. 1Google Search Console — queries you already get impressions for. Anything ranking positions 5–20 is a near-miss you can often improve cheaply.
  2. 2Google autocomplete, People Also Ask, and Related Searches — free, and drawn from real query data.
  3. 3Competitor gap analysis — terms competitors rank for and you do not. The most efficient single source.
  4. 4Customer language — support tickets, sales calls, reviews. People search using the words they already use.
  5. 5Keyword tools — for volume estimates and to expand seed terms into variants.

The Search Console source is consistently underused. Improving a page from position 12 to position 6 is usually far easier than ranking a new page from nothing, and the data telling you which pages are close is already sitting in your account.

Topic clusters

Modern search rewards demonstrated depth on a subject rather than isolated pages targeting isolated keywords. A topic cluster is a structure that signals that depth: one broad pillar page linked bidirectionally to several specific supporting pages.

For example, a pillar page on "technical SEO" supported by pages on crawl budget, robots.txt, canonical tags, structured data and Core Web Vitals — each linking up to the pillar, and the pillar linking down to each.

  • It clarifies to search engines which page is authoritative for the broad term.
  • Internal links distribute authority between related pages instead of stranding them.
  • It prevents keyword cannibalisation, where several of your own pages compete for one term and none of them win.
  • It gives you a content plan rather than a list of disconnected article ideas.

Turning research into a plan

  1. 1Collect broad seed terms describing what you do.
  2. 2Expand into variants and long-tail terms, then group by topic — not alphabetically or by volume.
  3. 3Assign intent to each group, which determines the page format.
  4. 4Filter by realistic difficulty for your site today.
  5. 5Map each group to one page. One page per intent; never two pages targeting the same intent.
  6. 6Prioritise by business value first and volume second. A 90-search-a-month term that converts beats a 9,000-a-month term that does not.

One intent, one page

The most common structural mistake is publishing several pages that all target the same intent. They split your own signals and compete with each other. If two keywords would be satisfied by the same page, they belong on the same page.

Frequently asked questions

How many keywords should one page target?

One primary keyword plus its close variants and synonyms. Modern search engines understand semantic relationships, so a page ranking for its main term typically ranks for dozens of related phrasings automatically. Targeting several unrelated terms on one page dilutes it.

Why do keyword tools disagree on search volume?

Volume is modelled, not measured. Each tool uses different data sources and clickstream models, and most round into buckets. Use one tool consistently for relative comparison rather than trusting any absolute number.

Should I target zero-volume keywords?

Sometimes. "Zero volume" often means below the tool's reporting threshold rather than genuinely unsearched. Very specific commercial terms with low reported volume can convert extremely well, particularly in niche B2B markets.

What is keyword cannibalisation?

When several pages on your own site target the same keyword and intent, so search engines split signals between them and rank none well. The fix is consolidating into one strong page and redirecting the others.

How often should keyword research be redone?

A full review quarterly, with continuous monitoring in between. Search behaviour shifts, competitors publish, and Search Console constantly surfaces new terms you have started appearing for.
