You write a blog. You publish it. You wait for traffic. But nothing happens.
Not because your writing is bad, but because you didn’t write what people are searching for.
Keyword research changes that. With free tools, you can find what users are searching and create content that ranks. Let’s begin.
What is Keyword Research?
Keyword research means:
- Finding the exact words people type into Google.
- When you use those keywords in your blog, Google understands your content and shows it to the right audience.
Why Keyword Research Matters
Keyword research helps you:
- Pick topics people are actively searching for
- Avoid guessing content ideas
- Rank faster and get traffic
Step-by-Step: How to Do Keyword Research for Free
Step 1: Identify Search Intent
Ask: Why is someone searching this keyword?
Intent | User Goal | Example |

Action | Find a tool/solution | keyword planner |
Match your content with user intent → Google ranks you faster.
Step 2: Use Google Search (Autocomplete + People Also Ask)

- I personally use morevGoogle Keyword Planner (inside Google Ads) — real search volume from Google.
How to use:
→ Open Google Ads → Tools → Keyword Planner

Step 4: Use KGR Method (Keyword Golden Ratio) — Rank With Zero Competition
KGR helps you find low-competition keywords that rank even on new websites.
KGR Formula:
- KGR = allintitle results / monthly search volume
- Search volume MUST BE less than 250 (from Google Keyword Planner)
How to check allintitle:
- Copy your keyword.
- Go to Google.
- Search using this format (use double quotes): allintitle: “how do I do keyword research for free
- Google will show a number at the top of the page, like: About 1 result
- That number = how many pages on the internet are using your exact keyword in their title.
- Lower allintitle → easier to rank.
KGR Example
Keyword | Search Volume (≤250) | allintitle result (from Google) | KGR |
how do I do keyword research for free | 100 | 1 | 1 / 100 = 0.01 ✅ |
KGR Value Interpretation Table (Understand Your Ranking Chances)
KGR Value Range | Competition Level | Ranking Chances |
< 0.25 | Very Low Competition | Ranks Faster (Best - use these keywords!) |
0.25 – 1.00 | Medium Competition | Can rank, but may take time / backlinks |
> 1.00 | High Competition | Avoid — too competitive |

Step 5: Choose Primary + Secondary Keywords
- There is no rule like “use only 5 keywords.”
- Use as many relevant keywords as possible naturally, not forcefully.
- Primary Keyword (focus keyword) Example:
→ how do I do keyword research for free - Secondary Keywords (supporting) Example:
→how to do keyword research for blog free
→SEO keyword research guide for beginners free
→which keyword is best for SEO?→how many SEO keywords should I use per page?
Long-Tail Keywords (Rank Faster)
Short Keyword | Long-Tail Keyword |
keyword research | how to do keyword research for blog free |
SEO tools | which free tool is best for keyword research |
Long-tail keywords = low competition + higher ranking chance.
Bonus: What Are Negative Keywords?
- Only for ads (not blogging).
- Negative keywords tell Google: don’t show my ad for this.
- Example (for digital marketing course ads):
❌ free
❌ PDF
❌ job
Prevents irrelevant clicks.
