If you know what your audience is searching for, you can:
-
create content they actually want,
-
rank higher on Google,
-
attract high-quality traffic,
-
and convert visitors into customers.
But most marketers still struggle with keyword research because they don’t follow a structured process.
This guide breaks down everything you need to know about keyword research with simple steps, tools, examples, tables, hacks, and strategies.
Let’s begin.
1. What Is Keyword Research?
Keyword research is the process of identifying the words and phrases people type into search engines.
These keywords help marketers:
-
understand what their audience wants,
-
create content that matches demand,
-
optimize websites for higher rankings,
-
run better ad campaigns,
-
and plan a long-term SEO strategy.
In simple words:
Keyword research tells you what your customers are searching for before they even reach you.
2. Why Keyword Research Matters for Marketers
Whether you’re a beginner or a pro, keyword research offers massive benefits:
✔ Drives organic traffic
Ranking on Google brings consistent, long-term traffic.
✔ Increases conversions
You attract people searching specifically for your solution.
✔ Saves advertising cost
High-intent, low-cost keywords reduce your paid ads budget.
✔ Helps understand customer needs
Keywords reveal pain points, questions, and motivations.
✔ Supports every marketing channel
SEO, social media, YouTube, and PPC keyword research power everything.
3. Types of Keywords You Must Understand
Before doing keyword research, marketers need to know key keyword types.
a) Short-Tail Keywords (1–2 words)
Example: “marketing tools”
-
High search volume
-
High competition
-
Low conversion rate
b) Long-Tail Keywords (3+ words)
Example: “best free marketing tools for startups”
-
Lower competition
-
Higher intention
-
Higher conversion
c) Branded Keywords
Example: “HubSpot CRM pricing”
These usually convert the best.
d) Informational Keywords
Example: “How to do keyword research”
Used to attract top-of-funnel traffic.
e) Commercial Keywords
Example: “best SEO tools for bloggers”
Used for comparison and decision-making.
f) Transactional Keywords
Example: “buy SEO tools subscription”
Used for sales-driven pages.
4. Understanding Search Intent (The Most Important Part)
Search intent tells you why the user is searching.
There are four types:
| Intent Type | Meaning | Examples |
|---|---|---|
| Informational | Learning something | “What is CRM?”, “How to start a blog” |
| Navigational | Going to a specific site | “YouTube Studio”, “Canva login” |
| Commercial | Researching before buying | “best laptops 2025”, “HubSpot vs Zoho” |
| Transactional | Ready to buy | “buy domain”, “SEO tools discount” |
If your content doesn’t match search intent, it will never rank.
5. Step-by-Step Process: How to Do Keyword Research
Here is the simplest and most effective keyword research process for marketers.
Step 1: Create Your Keyword Topics (Seed Keywords)
Start with broad topics related to your brand.
Example for a digital marketing company:
-

These seed keywords will help you expand to detailed keywords.

Step 3: Analyze Search Volume, Difficulty & Potential
Every keyword should be evaluated based on:
- Search Volume (How many people search it monthly)
- Keyword Difficulty (How hard it is to rank)
- CPC (Commercial value)
- Trends (Is it rising or falling?)
- SERP competition (Who’s ranking currently?)
Aim for:
-
Low difficulty + Medium volume = Best for new websites
-
High intent + Moderate volume = Best for conversions
Step 4: Find Long-Tail Keywords
Long-tail keywords bring higher-quality leads because they target specific user needs.
Examples:
-
“best CRM for small businesses in India”
-
“How to rank a new website in 2025”
-
“free keyword research tools for beginners”
Long-tail keywords give:
-
faster ranking
-
lower competition
-
better conversion rates
Step 5: Check Competitor Keywords (The Fastest Shortcut)
Competitor analysis is the easiest way to find proven keywords.
Steps:
-
Enter your competitor’s domain into Ahrefs/Semrush.
-
Check their top pages
-
Export their ranking keywords
-
Identify keyword gaps (where they rank but you don’t)
This helps you build content that can outperform them.
Step 6: Build Keyword Clusters (For Better Ranking)
Keyword clustering means grouping related keywords into one content piece.
Example cluster for “keyword research”:
-
How to do keyword research
-
keyword research tools
-
keyword strategy
-
long tail keywords
-
search volume analysis
This helps you:
-
rank for multiple keywords
-
improve topical authority
-
build a stronger content structure
Step 7: Finalize Your Keyword Strategy
Your final keyword list should include:
✔ Primary Keywords
(Main keyword for the content)
✔ Secondary Keywords
(Related supporting keywords)
✔ Long-Tail Variations
(Keywords for subheadings)
✔ LSI Keywords
(Topic-related words Google expects)
Example for one blog:
Primary Keyword: keyword research guide
Secondary Keywords: keyword tools, search intent
Long-tail Keywords: how to find keywords for SEO
Now you’re ready to create content
6. Keyword Research Table Example
