Ever wondered why some websites effortlessly rank at the top of Google, while others barely get noticed?
The secret lies in keyword research.
Keywords are the bridge between what people search and the content you create. The best part? You don’t need expensive tools like Ahrefs or SEMrush to find them.
In this guide, we’ll break down how to do keyword research for free — step by step — using real examples and free tools that actually work in 2025.
Why Keyword Research Matters
Keyword research is the foundation of SEO.
It helps you:
- Understand what your audience is searching for.
- Find content ideas that bring organic traffic.
- Identify low-competition opportunities.
- Increase conversions and visibility.
💡 Quick Fact: 68% of online experiences begin with a search engine (BrightEdge, 2025).
Without the right keywords, even the best content can go unnoticed.
Step-by-Step Guide — How to Do Keyword Research for Free
Step 1. Start with a Broad Topic (Seed Keyword)
Your seed keyword is a general term related to your niche.
For example:
If you run a fitness blog, your seed keywords could be:
- “weight loss”
- “home workouts”
- “healthy meals”
👉 These seed words will help you discover hundreds of keyword variations later.
Step 2. Use Google Autocomplete and Related Searches
Google itself is one of the best free keyword tools.
How to use it:
- Go to Google and type in your seed keyword (e.g., “home workouts”).
- Note the autocomplete suggestions that appear.
- Scroll to the bottom of the page — you’ll see “related searches.”
Example:
Typing “home workouts” might show:
- home workouts without equipment
- home workouts for beginners
- home workouts to lose belly fat
💡 These are real search terms people use every day.
Step 3. Explore Google Keyword Planner (Free Tool)
Google Keyword Planner is part of Google Ads — but it’s completely free to use with a Google account.
Steps:
- Go to Google Keyword Planner.
- Click on “Discover new keywords.”
- Enter your seed keyword.
- Analyze metrics like:
- Average monthly searches
- Competition level (Low, Medium, High)
- Top of page bid (shows keyword value)
Example:
“Home workouts for beginners” → 18K–30K searches/month, low competition.
Pro Tip:
Focus on long-tail keywords — they’re easier to rank for and convert better.
Step 4. Use Free Tools Like Ubersuggest or AnswerThePublic
→ Ubersuggest (by Neil Patel)
- Visit Ubersuggest.
- Enter your keyword and select your country.
- You’ll see:
- Keyword ideas
- Search volume

💡 The free plan offers 3 daily searches — perfect for beginners.
→ AnswerThePublic
- Visit AnswerThePublic.
- Enter a keyword.
- You’ll get a visual map of questions and phrases people ask around that topic.
Example:
“Blogging” →
- How to start a blog
- What makes a blog successful
- Which platform is best for blogging
Step 5. Check Keywords on Google Trends
Use Google Trends to check if a keyword is growing or declining in popularity.
Steps:
- Type in your keyword.
- Select your target country or region.
- Look for upward trends (steady or rising).
Example:
“AI tools for students” shows massive growth since 2023 — a great niche to target.
Step 6. Analyze Competitors’ Keywords (Without Paying)
You can spy on competitors’ keywords — for free!
How:
- Search your main keyword on Google.
- Open top-ranking pages.
- Use a free Chrome extension like Keywords Everywhere or SEO Minion to see the keywords used.
Tip:
Note down recurring keywords — these are proven to work in your niche.
Step 7. Filter and Organize Your Keywords
Once you’ve gathered 50–100 keyword ideas, filter them using:
- Search volume: Aim for 1K–30K monthly searches.
- Competition: Low to medium.
- Relevance: Match your content and audience.
You can use Google Sheets to categorize your keywords into:
- Informational (e.g., how to start a blog)
- Transactional (e.g., best blogging tools)
- Navigational (e.g., WordPress login)
Step 8. Use Free Chrome Extensions
Free browser tools can make keyword research faster:
- Keywords Everywhere → shows search volume & CPC right on Google.
- Surfer SEO Extension → helps you see competitors’ keyword density.
- MozBar → check website domain authority and keyword optimization.
Step 9. Validate Keywords with SERP Analysis
Before using a keyword, analyze its Search Engine Results Page (SERP):
Ask yourself:
✅ Are the top results blogs, videos, or product pages?
✅ Can I create something better or different?
✅ What content formats rank best (listicles, guides, how-tos)?
If you find outdated or low-quality results — that’s your chance to rank!
Step 10. Create Content Around Your Chosen Keywords
Once you have your final list, group them into content clusters.
Example:
| Main Keyword | Supporting Keywords |
| keyword research tools | free keyword research tools, how to find SEO keywords, keyword strategy |
| SEO tips | SEO for beginners, on-page SEO checklist, Google ranking tips |
Pro Tip:
Use your main keyword in:
- Title (H1)
- First paragraph
- Subheadings (H2/H3)
- Meta description
- Image alt text
But avoid keyword stuffing — keep it natural and humanized.
