How to Do Keyword Research with Semrush Like a Pro

Why Most People Fail at Keyword Research (And How You Can Avoid It)

Let me be honest with you.

When I first started learning SEO, keyword research felt confusing… even frustrating.

I’d open a tool, see thousands of keywords, and think:
“Which one should I actually use?”

I wasted weeks targeting keywords that never ranked.
No traffic. No clicks. Nothing.

But everything changed when I started using Semrush the right way.

Instead of guessing, I had data.
Instead of chasing random keywords, I had a clear strategy.

In this guide, I’ll show you exactly How to Do Keyword Research with Semrush Like a Pro — step by step — in a way that actually brings traffic (and results).

No fluff. Just what works.

What Is Keyword Research (And Why It Matters So Much)

Keyword research is simple:

It’s about finding what people are searching for on Google
And creating content around those searches

But here’s the truth most beginners miss:

Not all keywords are worth targeting.

Some are too competitive.
Some have no traffic.
Some don’t convert.

That’s where Semrush becomes powerful.

It helps you find:

• Keywords people are actually searching
• Keywords you can realistically rank for
• Keywords that bring traffic and money

Step-by-Step: How to Do Keyword Research with Semrush

try Semrush to find low-competition keywords faster!

Let’s break it down into a simple system you can follow today.

Step 1: Start with a Seed Keyword

A seed keyword is your starting point.

For example:

• “SEO tools”
• “affiliate marketing”
• “local SEO”
• “keyword research”

Go to Semrush → Keyword Overview and enter your seed keyword.

You’ll see:

• Search volume
• Keyword difficulty (KD)
• CPC (cost per click)
• Search intent

Pro tip:
Look at intent carefully. If it says commercial or transactional, it’s usually good for affiliate content.

Step 2: Use Keyword Magic Tool (This Is Where the Gold Is)

Now go to:
Keyword Magic Tool

Enter your seed keyword again.

This tool will show thousands of keyword ideas.

But don’t get overwhelmed. Focus on filtering.

Use these filters:

• KD (Keyword Difficulty): Under 30 (for beginners)
• Volume: 100–10,000 (sweet spot)
• Word count: 3+ (long-tail keywords)

Example results:

• “how to do keyword research with semrush”
• “best keyword research tool for beginners”
• “semrush keyword research tutorial”

These are called long-tail keywords — and they’re easier to rank.

Step 3: Analyze Keyword Difficulty (Don’t Skip This)

This is where most people go wrong.

They pick keywords like:
“SEO”
“make money online”

These are almost impossible to rank for.

Instead, check:

• KD% (Keyword Difficulty)
• Aim for:
  • 0–29 → Easy
  • 30–49 → Medium
  • 50+ → Hard

My rule:
If your site is new, stay under KD 30.

Step 4: Understand Search Intent (This Changes Everything)

Not all keywords are the same.

Semrush shows intent like:

• Informational
• Navigational
• Commercial
• Transactional

Examples:

• “What is keyword research” → Informational
• “Semrush pricing” → Commercial
• “Buy SEO tool” → Transactional

If you want affiliate sales, focus on:

• Commercial
• Transactional

If you want traffic, mix in:

• Informational

Step 5: Spy on Your Competitors (Easy Wins Here)

This is one of my favorite tricks.

Go to:
Domain Overview → Enter a competitor’s site

Then click:
Top Organic Keywords

You’ll see:

• What keywords they rank for
• Their positions
• Traffic share

Now ask:
“Can I create a better article than this?”

If yes — you’ve found a keyword opportunity.

This is how you find low competition keywords for Semrush.

Step 6: Use the Keyword Gap Tool (Underrated Strategy)

Go to:
Keyword Gap Tool

Add:

• Your site
• Competitor sites

Click compare.

Now you’ll see:

• Keywords your competitors rank for
• But you don’t

This is gold.

Focus on:

• Missing keywords
• Weak keywords (where competitors rank low)

Step 7: Build a Keyword List (Your Content Plan)

Don’t just pick one keyword.

Create a list like this:

Main keyword:

• how to do keyword research with semrush

Supporting keywords:

• semrush keyword research tutorial
• best keywords for SEO beginners
• low competition keywords semrush
• keyword research strategy 2026

Now you have:
A full article plan
Better SEO structure
Higher ranking chances
