Keyword Research Doesn’t Need Paid Tools
Most beginners think keyword research requires expensive tools like Ahrefs or Semrush.
Good news: you don’t need any of them to get started.
In fact, free tools often give you:
- cleaner data
- real Google insights
- unlimited searches
- faster decision-making
- higher accuracy for small sites
This guide will show you how to perform keyword research step-by-step using only free tools.
Simple, clear, practical – perfect for beginners and small websites.
1. Understand What Keyword Research Actually Means
Keyword Research is not:
❌ stuffing keywords
❌ collecting random word lists
❌ chasing high-volume topics
❌ guessing what people search
Keyword research is:
👉 Understanding what people want and creating content that solves their problems.
Good keyword research helps you:
- find topics
- understand what users need
- identify ranking opportunities
- reduce competition
- help Google understand your topic authority
If you get this mindset right, tools become simple helpers – not the main focus.
2. Start With Search Intent (The Foundation of Keyword Research)
Before searching for keywords, understand the intent behind a search.
Here are the four main types:
A. Informational (Learn something)
Examples:
- how to fix crawled not indexed
- what is internal linking
- how search engines work
These usually need tutorials or guides.
B. Navigational (Go to a website)
Examples:
- google search console
- wordpress login
- canva blog
C. Transactional (Buy something)
Examples:
- best hosting for wordpress
- buy seo tools
- semrush discount
These are high commercial intent.
D. Comparative (Compare options)
Examples:
- elementor vs gutenberg
- rank math vs yoast
- ahrefs vs semrush free tools
These usually have high ranking potential because people want clarity.
Understanding search intent helps you choose the right keyword type for your content.
3. Use Google Search Console (GSC) As Your First Keyword Tool
If your site is live, GSC is the most accurate free keyword tool.
✔️ Go to:
Search Console → Performance → Search results
Look for:
A. Queries with impressions but low clicks
These are ranking opportunities.
B. Queries on Page 2 (positions 11–20)
These can move to Page 1 with simple improvements.
C. Queries you didn’t know you ranked for
These help you find new topics.
Simple strategy:
- Sort by impressions
- Check positions 10–30
- Turn those queries into full articles
- Add them to existing posts as semantic keywords
This improves rankings very quickly.
4. Use Google Keyword Planner (Zero-cost, powerful data)
Go to Google Ads → Tools → Keyword Planner.
You can use it without running ads.
Steps:
- Click Discover new keywords
- Enter your topic (e.g., “seo tools”, “site indexing”)
- Set location to your target country
- Export ideas
What to look for:
- Low/Medium competition
- Relevant variants
- High intent searches
- Longtail keywords
Examples:
- “why is my page not indexing”
- “best free keyword tools”
- “how to check backlinks free”
Keyword Planner shows broad ranges, but the ideas themselves are powerful.
5. Use Google Trends for Seasonal & Topical Ideas
Go to Google Trends → Enter your keyword.
What to check:
A. Consistency
Does the topic stay stable over time?
B. Rising topics
These indicate trending content opportunities.
C. Region-specific demand
Perfect for targeting a specific audience.
D. Related queries
Often-free keyword goldmines.
Example rising queries:
- “ai seo tools”
- “site indexing issue”
- “google algorithm update”
These give you immediate content ideas.
6. Use AnswerThePublic for Question-Based Keywords
People search with questions.
AnswerThePublic shows:
- what
- why
- how
- when
- can
- does
For example, “site indexing” generates:
- Why is Google not indexing my site?
- How do I check if my page is indexed?
- How long does indexing take?
These can become article sections or full articles.
7. Use “People Also Ask” (PAA) on Google SERP
Search your keyword on Google.
Look for the People Also Ask box.
You will find:
- real user questions
- easy-to-answer queries
- low-competition longtails
Example for “internal linking”:
- how many internal links per page
- does internal linking help SEO
- should internal links open in new tab
Use these as H2/H3 inside your article.
8. Use ChatGPT for Keyword Clustering (Free + Extremely Effective)
You can paste your keywords into ChatGPT and ask:
“Cluster these keywords into topic groups.”
You’ll get:
- topic clusters
- pillar + subtopic ideas
- content calendar suggestions
- internal linking suggestions
This makes your content organized and authoritative.
9. Build Topic Clusters (Most Important Step)
Google ranks topics, not isolated articles.
Let’s say your site focuses on SEO.
A topic cluster can be:
Pillar Page:
Search Engine Optimization: Beginner-Friendly Guide
Cluster Articles:
- How search engines work
- Keyword research using free tools
- On-page SEO checklist
- Internal linking guide
- Technical SEO basics
- Fixing indexing issues
Internal linking these pages creates topical authority.
10. Choose Low-Competition Longtail Keywords First
Examples:
❌ “SEO tools” (very hard)
✔️ “best free SEO tools for beginners”
❌ “keyword research”
✔️ “keyword research using free tools only”
❌ “site indexing”
✔️ “why is my site not indexing and how to fix it”
These have:
- lower competition
- faster ranking
- easier content creation
- higher user satisfaction
Perfect for new websites.
11. Create a Simple Keyword Spreadsheet
Columns:
- Keyword
- Intent
- Competition level
- Search demand
- Target page
- Priority
- Notes
This keeps your strategy clean and consistent.
12. Avoid Keyword Stuffing – Use Semantic Alternatives
Instead of repeating:
“keyword research”
“keyword research”
“keyword research”
Use variations:
- find keywords
- search queries
- keyword ideas
- content opportunities
- topic discovery
Google understands synonyms naturally.
13. How to Turn Keywords Into High-Ranking Content
Structure your content like this:
✔️ Start with a clear answer
Google loves “fast clarity.”
✔️ Add steps (AIO friendly)
Search engines extract list-based structures easily.
✔️ Add a real example
Shows experience and EEAT.
✔️ Add internal links
Helps Google classify your topic.
✔️ Add a helpful conclusion
Summarize your solution clearly.
14. Common Keyword Research Mistakes to Avoid
❌ Chasing high-volume keywords
❌ Ignoring search intent
❌ Publishing content with no cluster
❌ No internal linking
❌ Writing for Google, not users
❌ Using only one keyword per page
Avoid these, and your keyword strategy becomes much stronger.
