How to Do Keyword Research for Free: A Step-by-Step Method Using Google's Own Tools
To do keyword research for free, start with the queries you already appear for in Google Search Console, expand them with Google Keyword Planner and Google Trends, then study the search results page for intent, questions and competition. Group what you find by intent, choose one primary topic per page, and prioritize topics where you can offer something better or more specific than what ranks today.
You don't need a paid SEO suite to do this well. Paid tools add convenience and competitor data, but Google's own free tools show real demand and your real performance.
Key takeaways
- Search Console shows real queries, impressions, clicks and positions for your site; mine it first.
- Keyword Planner is free to use but needs a completed Google Ads account with billing details for keyword ideas.
- Google Trends shows relative interest over time and by region, which is ideal for seasonality and local wording.
- The results page tells you intent: what format Google rewards and which questions people ask.
- Group keywords by intent; one page per intent avoids pages competing with each other.
- With AI search, research questions and needs, not just exact-match phrases.
Step 1: Mine Google Search Console
If your site has been live for a while, this is the richest free source because it shows what Google already associates you with.
- Open Performance > Search results. Google's documentation says the default view shows clicks and impressions for the past three months; widen the date range for more data.
- Turn on Impressions, Clicks, CTR and Average position.
- Use the Queries tab, then the Pages tab to see which page ranks for what. You can also group by country and device.
- Export the data.
Look for three kinds of opportunity:
| Opportunity | How to spot it | What to do |
|---|---|---|
| Striking distance | High impressions, average position roughly 5–20 | Improve the page: better answer, more depth, internal links |
| Low CTR | Good position, low click-through rate | Rewrite the title and meta description to match intent |
| Unexpected queries | Queries you didn't target but appear for | Add a section, or create a dedicated page if the intent differs |
Use a regex filter on queries such as ^(how|what|why|which|can|is|best) to pull out question queries, which are prime candidates for direct-answer sections.
Note that Google says your site might not appear when you run the same query yourself, because results depend on time, place, device and history. Trust the aggregated data more than spot checks.
Step 2: Expand ideas with Google Keyword Planner
Keyword Planner is built for Google Ads, but it works for SEO research. According to Google's help center, it lets you:
- Discover new keywords from words, phrases or a website URL
- See monthly search estimates for keywords
- View cost estimates (useful as a proxy for commercial value)
- Organize keywords into categories
Access requirements: Google says you must complete your Google Ads account setup, including billing information, to use basic features like "Get ideas for new keywords." You don't have to run a campaign to research keywords.
How to use it for SEO:
- Choose Discover new keywords and enter three to five seed terms describing your offer, or your competitor's URL.
- Set the location and language to your real market (for example Pakistan and English, or the UAE and Arabic).
- Export the ideas and remove irrelevant ones.
- Use the volume estimates to compare relative demand, not to forecast traffic precisely. Google notes that performance depends on many factors beyond the estimates.
Step 3: Check seasonality and regions with Google Trends
Google Search Central describes Trends as a random sample of aggregated, anonymized Google and YouTube searches, letting you analyze interest by topic or query from global to city level. Use:
- Explore to compare terms, check interest over time and see regional differences and related queries
- Trending now to see what's rising, with approximate search volume and related news
Practical uses:
- Pick the right wording. Compare "invoice template" vs "bill format," or "mobile" vs "cell phone," in your target country.
- Time your content. Publish seasonal pages (Ramadan, Black Friday, tax season) well before interest peaks.
- Spot rising topics early in your niche.
Google's own advice: make sure a topic fits your business and users; don't write about something just because it's trending.
Step 4: Read the search results page
The results page is a free intent and competition report. Search each priority keyword (signed out or in a private window, set to your target country) and note:
- Result types: product pages, guides, videos, local map pack, forums, tools. This tells you what format Google thinks satisfies the query.
- Whether an AI Overview appears and which sources it cites.
- "People also ask" questions and related searches, which reveal sub-questions to answer.
- Autocomplete suggestions as you type, including letter-by-letter variations.
- Who ranks: big brands, niche experts, forums? Can you realistically offer something better?
- Gaps: outdated information, missing local details, no first-hand experience.
If results for "best CRM" are all huge publishers, a narrower angle like "best CRM for a five-person real estate team in Dubai" may be both more winnable and more useful.
Step 5: Use other free sources of real language
- Customer emails, sales calls and support tickets: the exact words customers use
- Forums and communities such as Reddit, Quora and niche groups: the problems people describe in their own words
- YouTube search suggestions: how people phrase "how to" queries
- Your site search logs: what visitors look for and can't find
- Competitor navigation and headings: how others structure the topic (for inspiration, not copying)
Step 6: Group keywords by intent and map them to pages
Put every keyword in a spreadsheet with columns for keyword, intent, volume estimate, current ranking page (if any) and notes. Then group.
| Intent | Example query | Best page type |
|---|---|---|
| Informational | how to reduce cart abandonment | Guide or how-to article |
| Commercial investigation | shopify vs woocommerce | Comparison page |
| Transactional | buy standing desk 160cm | Product or category page |
| Local | dentist near me open saturday | Location page plus Business Profile |
| Navigational | brand name login | Homepage or login page |
Rules for mapping:
- One primary intent per page. If two keywords need different answers, they need different pages.
- Merge close variants. "Keyword research free" and "free keyword research" belong on one page.
- Avoid creating near-duplicate pages for wording variations. Google's guidance on generative AI search says its systems understand synonyms and meaning, and creating pages for every variation to manipulate rankings can fall under scaled content abuse. See programmatic SEO done right, without spam.
- Assign existing pages first, then list gaps that need new pages.
For local businesses, map local-intent keywords to location pages and your profile; see the Google Business Profile optimization checklist.
Step 7: Prioritize
Score each page opportunity on:
- Business value: does this audience buy what you sell?
- Demand: relative volume and trend direction
- Winnability: can you create the best answer, given who ranks now?
- Effort: improving an existing page is usually faster than starting fresh
Start with striking-distance improvements from Search Console, then high-value gaps where you have real expertise.
Keyword research in the age of AI search
AI Overviews, AI Mode and assistants like ChatGPT break questions into sub-questions (Google calls this query fan-out). That shifts the goal:
- Research questions and tasks, not only head keywords.
- Build pages that answer the main question and its natural follow-ups in one place.
- Add original information (data, experience, examples) so your page is worth citing.
Read the generative engine optimization guide and how to rank in Google AI Overviews for how to turn research into citable content.
From experience: When researching keywords for puzzle and activity books on Amazon KDP, the most useful insights came from looking at what real buyers typed and what already sold, not from the biggest volume numbers. Websites work the same way: specific, intent-rich phrases from real customers usually beat broad terms with impressive volume.

Frequently asked questions
Is Google Keyword Planner really free?
You can use Keyword Planner without running ads, but Google says you must complete your Google Ads account setup, including billing information, to access basic features like getting new keyword ideas. Treat its volumes as estimates. It's still useful for discovering related keywords and comparing relative demand.
What is the best free keyword research tool?
For an existing site, Google Search Console is the most valuable because it shows the real queries your pages already appear for, with impressions, clicks and positions. For new topics, combine Keyword Planner for ideas and volume estimates, Google Trends for seasonality and regional interest, and the search results page itself for intent and questions.
How do I find keywords I can actually rank for?
Look for queries where you already get impressions but sit outside the top few positions, and for specific, lower-volume questions your competitors answer poorly. Search each one and check what ranks: if results are dominated by large brands with deep pages, choose a narrower angle. Your first-hand expertise is your advantage on specific questions.
Do keywords still matter with AI search?
Yes, but differently. Google says its AI systems understand synonyms and meaning, so you don't need every long-tail variation or a page per wording. Keyword research now matters mainly for understanding what people need, which questions they ask, and how to organize topics into strong pages, rather than for repeating exact phrases.
How many keywords should one page target?
One primary topic or intent per page, plus the closely related questions and phrasings that someone with that intent would also have. If two keywords need different answers, they need different pages. If they would be answered by the same content, keep them together on one page to avoid competing pages.
