How to Do Keyword Research in 2026 (Step by Step)
The short answer: Keyword research is finding the words and questions your audience types into Google and asks AI tools, then choosing the ones you can realistically win and building pages around them. In 2026 it works in eight steps: start from your business, collect ideas, get the numbers, check the intent, size up the competition, group keywords into topics, find the AI-style questions, and prioritize. This guide walks through each one with free tools you can use today.
A lot of keyword research advice still teaches the 2015 version: find a high-volume keyword, put it in your title, repeat it a few times. That approach wastes months. Search has changed, and so has the way you should pick what to write about.
Key Takeaways
- Start from your business, not a tool. The best keywords come from what your customers actually ask.
- Search volume is an estimate. Use it to compare keywords, not as an exact count.
- Intent beats volume. A smaller keyword that matches what you sell is worth more than a big one that doesn’t.
- Target topics, not single keywords. One strong page can rank for hundreds of related searches.
- Add AI-style questions. People ask AI tools longer, more specific questions, and those questions shape what Google’s AI answers pull in.
What Changed About Keyword Research in 2026
Three things matter more now than they did a few years ago.
Searches are getting longer. Google reported in May 2026 that the average AI Mode search is three times longer than a traditional search. People are typing full questions with context, not two-word phrases.
A lot of searches are brand new. Google’s John Mueller said in 2025 that about 15% of all queries are new every day, and that this hasn’t dropped despite AI. No keyword tool can show you a search nobody has made before. That’s why covering a topic well beats chasing an exact phrase.
Most keywords are long tail. A Backlinko study of 306 million keywords found that 91.8% of all keywords get 100 or fewer searches a month. The data is from 2020, and with searches getting longer, the long tail is likely even bigger today. The opportunity is in the specific questions, not the handful of giant keywords everyone fights over.
What hasn’t changed: you still need to know what people search for, how hard it is to rank, and whether the traffic is worth having. That’s what the steps below cover.
Step 1: Start With Your Business, Not a Tool
Before you open any keyword tool, write down:
- What you sell or offer. Your products, services, or the topics your site covers.
- Who you’re writing for. Beginners or experts, buyers or researchers, local or global.
- The questions customers ask you. Check your emails, sales calls, comments and support chats. These are gold, because they’re real.
From that, write 5 to 10 seed topics: short, broad terms that describe your area. A home coffee blog might start with “pour over coffee,” “espresso at home,” “coffee grinder,” “cold brew” and “coffee beans.”
Seeds aren’t keywords you’ll target directly. They’re starting points for finding the specific searches underneath them.
Step 2: Collect Keyword Ideas
Now expand each seed into dozens of real searches. Use several sources, because each one shows you something different.
Free sources:
- Google autocomplete: type your seed into Google slowly and note the suggestions. Add letters (“pour over coffee a”, “pour over coffee b”) to find more.
- People Also Ask: search your seed and open the questions box. Each answer you open loads new questions.
- Related searches: scroll to the bottom of Google’s results page.
- Google Search Console: if your site is live, the Performance report shows the actual searches you already get impressions for. These are keywords Google already connects with you.
- Reddit and Quora: search your topic and read how people phrase their problems. You’ll find questions no tool lists.
- AI tools: ask ChatGPT or Gemini “What questions do beginners ask about pour over coffee?” They’re good at generating question ideas. They can’t tell you search volume, so treat their output as ideas only.
Competitor pages: search your main topics, open the top-ranking pages, and look at their subheadings. A keyword tool can also show which searches a competitor’s page ranks for.
Put everything into one spreadsheet. Aim for 50 to 200 ideas before filtering.
Step 3: Get the Numbers
For each idea, you want three numbers:
| Metric | What it tells you | How to use it |
|---|---|---|
| Search volume | Roughly how many times a month people search it | Compare keywords against each other |
| Keyword difficulty | How hard it is to rank on page one, usually 0 to 100 | Match it to your site’s strength |
| CPC (cost per click) | What advertisers pay per click | A high CPC usually signals buying intent |
A warning about search volume: no tool gives you an exact number. Google’s own Keyword Planner shows rounded averages grouped into buckets, and other tools estimate from different data. Ahrefs itself describes its numbers as “directionally accurate.” Use volume to ask “is this keyword bigger or smaller than that one?”, not to predict your exact traffic.
About difficulty: every tool calculates it differently, so a 30 in one tool isn’t a 30 in another. Pick one tool and compare keywords inside it.
Step 4: Check the Search Intent
Search intent is what the person actually wants when they type a keyword. Get this wrong and you won’t rank, however good your content is.
| Intent | What they want | Example | Best page type |
|---|---|---|---|
| Informational | To learn something | “how to make pour over coffee” | Guide or tutorial |
| Commercial | To compare before buying | “best coffee grinder under $100” | Comparison or review |
| Transactional | To buy or sign up now | “buy baratza encore” | Product or pricing page |
| Navigational | To reach a specific site | “starbucks menu” | That brand’s page |
The fastest way to check intent: search the keyword and look at what already ranks. If the top 10 are all step-by-step guides, Google has decided that’s what people want. Don’t try to rank a product page there.
Also look at the results page itself. If you see an AI Overview, a video box or a “People also ask” box, note it. Those tell you the format Google expects and where else you can show up.
Step 5: Check If You Can Actually Win
This is the step most people skip, and it’s why their content never ranks.
Search the keyword and study page one:
- Who’s ranking? If it’s all huge brands and big publishers, a newer site will struggle. If you see forums, Reddit threads, thin articles or small blogs, that’s a sign of weak competition.
- How good is the content? If the top results are outdated, shallow or don’t fully answer the question, you have an opening.
- How strong are those sites? Compare their authority with yours in your SEO tool. A brand-new site should start with keywords where at least a few results come from sites similar in size to yours.
The beginner rule: a new site should target low-difficulty, specific keywords first. Win those, build authority, then go after the bigger terms.
Step 6: Group Keywords Into Topics
Don’t write one page per keyword. Write one page per topic and intent.
Google understands that “how to make pour over coffee,” “pour over coffee steps” and “pour over brewing guide” all want the same answer. One strong page can cover all of them. Ahrefs has found that a typical top-ranking page ranks for about a thousand related keywords.
How to group:
- Sort your spreadsheet so similar keywords sit together.
- Search two keywords you think belong together. If Google shows mostly the same results for both, they belong on the same page.
- If the results are different, they need separate pages.
Then build topic clusters: one main guide on a broad topic, linked to several detailed posts on specific subtopics, all linking back to each other. This shows Google your site covers the subject in depth.
Step 7: Find the AI-Style Questions
This is the step that makes keyword research work for AI search too.
When Google builds an AI Overview, it splits the question into several related sub-questions and searches each one. We cover this in detail in How to Get Cited in Google AI Overviews. For keyword research, it means the specific questions around your main keyword matter as much as the keyword itself.
To find them:
- Collect every “People also ask” question for your main keyword.
- Ask your topic in Google AI Mode and note what each section of the answer covers.
- Think in full sentences. Instead of “coffee grinder,” think “what grinder should a beginner buy for pour over coffee under $100?” That’s how people now ask AI tools.
Then answer these questions inside your main page, each under its own clear subheading, with the answer in the first sentence. You’ll rank for the keyword in Google and give AI engines clean answers to quote. If you’re new to this side of search, our guide on what GEO is explains how it works.
Step 8: Prioritize and Build Your Plan
You’ll end up with far more topics than you can write. Score each one so you write the right ones first.
| Factor | Question to ask | Score 1 to 3 |
|---|---|---|
| Business value | Does this topic lead to what I sell? | 3 = directly |
| Winnability | Can my site realistically reach page one? | 3 = yes, soon |
| Demand | Is there enough search interest to matter? | 3 = clear demand |
Add the scores and start with the highest totals. A topic that scores high on business value and winnability beats a high-volume topic you can’t rank for.
Finally, map each chosen topic to one page: an existing page to improve, or a new one to write. Record the main keyword, the related keywords and the intent in your spreadsheet, so every page has a clear job.
Before you publish each page, run it through our on-page SEO checklist.
Common Keyword Research Mistakes
- Chasing volume only. A huge keyword you can’t rank for brings zero traffic. If your site already gets little or no traffic, see why your website isn’t getting traffic.
- Ignoring intent. Writing a blog post for a keyword where Google shows product pages.
- One page per keyword variation. This splits your authority, and your own pages end up competing with each other.
- Trusting volume as exact. It’s an estimate. Real traffic often comes from the related searches no tool shows.
- Never checking results. Re-check Search Console every month to see which searches your pages actually appear for, and update your plan.

FAQ
How many keywords should I target per page?
One main keyword plus its close variations and related questions. If two keywords show mostly the same Google results, target them on the same page. If the results differ, give each its own page.
What keyword difficulty should a new website target?
Start with the lowest-difficulty keywords your tool shows that still match your business, and confirm by checking page one yourself. If you see small sites, forums or weak content ranking, it’s a realistic target. Since every tool measures difficulty differently, the page-one check matters more than the exact number.
Is search volume accurate?
No. Every tool estimates it, and Google’s Keyword Planner rounds and groups its numbers. Use volume to compare keywords against each other, not to predict exact traffic. Your Search Console data shows real numbers once your pages are ranking.
Does keyword research still matter with AI search?
Yes, but it has expanded. You still need to know what people search for in Google. Now you also need to cover the longer, more specific questions people ask AI tools, because those shape which pages Google’s AI answers and AI assistants cite.
How often should I redo keyword research?
Do a full round when you plan new content, and check Search Console monthly. New searches appear constantly, so your best new keywords often come from the queries your existing pages already get impressions for.
The Bottom Line
Keyword research in 2026 isn’t about finding one magic keyword. It’s about understanding what your audience asks, picking the topics you can win, and covering each one well enough that Google ranks it and AI engines quote it.
Start from your business, collect real questions, check intent and competition, group keywords into topics, and add the AI-style questions. Do that, and every page you publish has a clear reason to exist and a real chance to rank.
