Keyword research is still the foundation of every SEO strategy that works even in an era of AI Overviews and answer engines. If you're not sure why SEO still matters in 2026, that case is made in full here. Here's how to find the terms worth targeting, judge whether they're worth the effort, and turn them into a content plan.
Every piece of content that ranks starts the same way: someone typed a question, a phrase, or a handful of words into a search bar. Keyword research is the practice of figuring out what those words are, how many people are typing them, what they actually want when they do, and which of those searches are worth building content around.
Done well, it turns guesswork into a plan. Done poorly — or skipped entirely — it leads to content that's well-written but invisible, because it was never built around a search that real people make.
Search Volume vs. Keyword Difficulty

1 Start With Seed Keywords
Seed keywords are the broad, obvious terms that describe your business, product, or topic before any research tool touches them. If you sell running shoes, your seeds might be "running shoes," "trail runners," or "marathon training shoes." They're rarely worth targeting directly — they're too broad and too competitive — but they're the input every keyword tool needs to generate the hundreds of related terms underneath them.
A good way to build a seed list:
- List every product, service, or topic your business covers, in plain language
- Add the questions customers actually ask in sales calls, support tickets, or reviews
- Check your own site search and analytics for terms people are already using to find you
- Note what competitors rank for that you don't
2 Expand With Keyword Research Tools
Once you have seeds, a keyword tool expands them into the long list of related searches, along with data on volume, competition, and trend. None of these tools show the full picture on their own — search engines don't publish exact numbers — but they're directionally reliable enough to prioritize against.

Google Search Console's Performance report shows the exact queries your site already gets impressions for — including ones you rank for on page 2 or 3 without realizing it. Those are often the fastest wins, since you're improving an existing ranking rather than starting from zero.
3 Evaluate Each Keyword on Three Metrics
A long list of keywords isn't a strategy — it's a spreadsheet. The next step is scoring each term so you know which ones deserve a page and which ones don't.
| Metric | What it tells you | Watch out for |
|---|---|---|
| Search volume | How many people search this term per month | High volume often means high competition and vague intent |
| Keyword difficulty | How hard it is to rank, based on current top-ranking pages | Tool scores vary — treat as a rough guide, not gospel |
| Business relevance | Whether ranking for it would actually drive qualified traffic | The easiest keywords to rank for are often the least valuable |
A mid-volume keyword with clear commercial or informational relevance to your business is almost always a better target than a high-volume keyword that only loosely relates to what you offer.
4 Read Search Intent, Not Just Volume
The same keyword can hide different intents depending on phrasing. "Best running shoes" is comparison intent — someone deciding between options. "Buy running shoes online" is transactional — someone ready to purchase. "How do running shoes fit" is informational. Targeting the wrong intent with the wrong content type is one of the most common reasons a well-optimized page still doesn't rank: Google has already decided what kind of result satisfies that query, and it won't rank a page that doesn't match.
Before writing anything, search the term yourself and look at what's already ranking. If the top ten results are all product listing pages, a blog post probably won't outrank them, no matter how well it's written. Once you know what format the intent demands, the question of how much of that content AI can write for you is worth thinking through before you start.
Common mistake
Chasing a high-volume keyword with the wrong content format. Volume tells you demand exists; the search results tell you what format satisfies that demand. Ignore the second part and even great content underperforms.
5 Don't Skip Long-Tail Keywords
Long-tail keywords are longer, more specific phrases — "best trail running shoes for wide feet" instead of "running shoes." Individually, they carry a fraction of the search volume of their broader parent terms. Collectively, they often represent the majority of total search traffic in a given topic, and they tend to convert better because the searcher knows exactly what they want.
Long-tail terms are also where newer or smaller sites can realistically compete, since established competitors are usually focused on the broad head terms.
6 Group Keywords Into Clusters
Rather than building one page per keyword, group related keywords into topic clusters — sets of terms that reflect the same underlying search intent and could reasonably be answered by the same page. This does two things: it prevents you from publishing five thin pages that all compete with each other for the same intent, and it signals topical depth to search engines, which increasingly reward sites that cover a subject comprehensively rather than scattering it across disconnected posts.
A typical cluster has one comprehensive "pillar" page targeting the broad term, supported by several narrower pages targeting related long-tail and question-based terms, all internally linked together.

7 Check What's Already Ranking
For every keyword you're seriously considering, look at the current top results and ask what they have in common: format (list, guide, comparison, product page), depth, angle, and what they're missing. The gap between what exists and what a searcher actually needs is usually where the opportunity is — not in writing a longer version of the same thing, but in answering the question more directly, more currently, or more usefully.
8 Map Keywords to the Funnel
Not every keyword belongs at the same stage of content. Mapping keywords to funnel stage keeps a content plan balanced instead of tilted entirely toward top-of-funnel traffic that never converts.
- Awareness — broad, informational terms ("what is keyword research")
- Consideration — comparison and evaluation terms ("best keyword research tools")
- Decision — transactional, high-intent terms ("keyword research tool pricing")
9 Revisit Keyword Research Regularly
Search behavior shifts — new products launch, language changes, and how people phrase questions to AI-powered search tools doesn't always match how they phrase typed queries. Keyword research isn't a one-time exercise before a content calendar; it's worth revisiting quarterly, and especially whenever a new content pillar or product line is added.
Bringing It Together
Keyword research works best as a repeatable process: build seed terms, expand them with data, evaluate volume against relevance and difficulty, read intent from the actual search results, group related terms into clusters, and map the result to the stages of your funnel. None of these steps individually is complicated — the value comes from doing all of them in order, instead of jumping straight from a keyword tool export to a content calendar.

Frequently Asked Questions
How many keywords should one page target?
Usually one primary keyword plus a handful of closely related variations and long-tail phrases that share the same intent. Trying to target multiple unrelated intents on one page tends to dilute relevance for all of them.
Is keyword research still relevant with AI search and answer engines?
Yes, AI-driven search tools still rely on understanding what a query means and matching it to content that answers it well. The mechanics of discovery are shifting, but the underlying need to understand what people are actually asking hasn't gone away.
What's a reasonable keyword difficulty to target for a newer site?
There's no universal number — difficulty scores vary by tool and don't account for your site's specific authority. A more reliable approach is to check who's currently ranking and honestly assess whether you can produce something as good or better.
