Keyword research is finding the words, phrases and questions your audience actually searches for, then judging which are worth targeting. In 2026 it is not just about search volume: it is about matching the right intent, and increasingly about the questions people ask AI answer engines, not only the keywords they type into Google.
What is keyword research?
Keyword research is the practice of identifying what your audience searches for, and deciding which of those searches you should try to win. It is the foundation of both SEO and content strategy: you cannot optimise for demand you have not identified. Today it spans two things at once, the keywords people type into Google and the questions they ask answer engines like ChatGPT and Google AI Overviews.
Why does keyword research matter?
Without it, you are guessing. Skip the research and you end up writing content nobody searches for, competing for terms you cannot realistically win, or targeting the wrong intent so the traffic never converts. Done well, it points your effort at demand that actually exists and that you have a chance of capturing. It also underpins the keyword map that keeps your pages from competing with each other, which we come to below.
How do you do keyword research?
A repeatable process beats a big one-off list:
- Start with seed terms. The core topics of your business, described in your customers' words, not your internal jargon.
- Expand them. Use Google autocomplete, the "people also ask" and related searches on the results page, and, best of all, the queries you already earn impressions for in the Search Console Performance report.
- Add data. Rough search volume and difficulty help, but weigh them against relevance to your business.
- Judge intent. Work out what each searcher actually wants, covered next.
- Prioritise. Relevance, intent and winnability first. A term you can win that matches a buyer beats a bigger term you cannot.
The fastest wins are often hiding in your own Search Console data: terms you already rank for on page two, where a better-targeted page could push you up. Many of your best opportunities will be long-tail, the longer, more specific phrases; see how to find long-tail keywords for that in depth.
How do you read search intent?
Search intent is what the person is actually trying to do, and it comes in four broad types: informational (to learn), commercial (to compare), transactional (to buy) and navigational (to reach a specific site). Each wants a different kind of page, and targeting a keyword with the wrong type of page is one of the most common reasons content fails to rank. For how to work out a keyword's intent and match your page to it, see how to read search intent.
How do you research questions for AI search?
This is the part traditional keyword research misses. Answer engines are driven by questions, so your research should capture the questions your customers ask, not only the keywords they type, then turn each into a section or page that answers it directly, the core move in Answer Engine Optimisation. For where to find those questions, how to prioritise them and how to turn them into content, see how to research questions for AI search.
How do you map keywords to pages?
Research is only half the job; the other half is assignment. Give each page one primary target, and write it down. This keyword map is the single best defence against keyword cannibalisation, where two of your own pages compete for the same term and neither wins. Group closely related terms under the page that owns their intent, and never split one intent across several pages. A little mapping discipline up front saves a lot of untangling later.
How does Limecube help?
Limecube's keyword workspace is where this whole process actually happens, per client, not in a spreadsheet you forget. You do the research in the tool: build and expand your keyword lists, and surface the questions your customers ask. It flags the questions worth answering for AI visibility and scores how well your existing pages cover them, so the gaps are obvious.
It also does the mapping for you: every keyword is assigned to the page that should own it, and when a page has drifted onto too many terms, the tool suggests which existing page each one really belongs to, so you can re-map and head off keyword cannibalisation before it costs you rankings. Research, questions and mapping in one place, which is exactly what stops your content competing with itself. The 7-day trial covers it.
