If content is king, then keywords are the map to the kingdom.

How to Do Keyword Research Step-by-Step
1. Start with Seed Topics
Begin with broad topics relevant to your business. For example, if you sell fitness gear, seed topics could be:
-
Home workouts
-
Strength training
-
Running shoes
From here, you’ll expand into related keywords.
2. Find Related Keywords
Use keyword tools to find:
-
Short-tail keywords (e.g. “running shoes”)
-
Long-tail keywords (e.g. “best running shoes for flat feet”)
-
Question-based keywords (e.g. “how to clean running shoes”)
Focus especially on long-tail keywords—they’re less competitive and often have higher intent.
3. Analyze Search Intent
Not all keywords are created equal. You need to match search intent—the “why” behind the search.
Four main types:
-
Informational: Looking for knowledge (“what is HIIT training”)
-
Navigational: Looking for a specific brand/site (“Nike running shoes”)
-
Transactional: Ready to buy (“buy waterproof headphones”)
-
Commercial Investigation: Comparing before buying (“best noise-canceling earbuds 2025”)
Match your content format to the intent. Don’t target a “buy now” keyword with a how-to blog post.
4. Check Keyword Metrics
Look at:
-
Search volume – How many people search for this per month?
-
Keyword difficulty (KD) – How competitive is it to rank?
-
CPC (cost per click) – How valuable is this keyword in paid ads?
Aim for a balance: moderate volume, low-to-medium difficulty, and high intent.
5. Spy on Competitors
Check what keywords your competitors are ranking for using Ahrefs, SEMrush, or Ubersuggest.
Ask:
-
What content is performing well?
-
Which keywords are bringing them traffic?
-
Are there any content gaps you can fill?
Bonus Tips for Smarter Keyword Targeting
Use Keywords Naturally
Don’t stuff keywords. Instead, include them in:
-
Title and URL
-
Headings (H1, H2s)
-
Meta description
-
First 100 words
-
Image alt tags
Write for humans first, algorithms second.
Group Keywords by Topic
Instead of one keyword per post, group related terms to target a broader topic. This supports semantic SEO and helps Google understand your content’s depth.
For example, a post about “content calendars” might also target:
-
how to build a content calendar
-
free content calendar templates
-
editorial calendar tools
Refresh and Update
Revisit your keyword strategy every few months. Search behavior evolves, and so should your content.
Use tools like Google Search Console to spot emerging keyword opportunities based on what you’re already ranking for.
Final Thoughts
Keyword research isn’t just for SEO geeks—it’s the foundation of effective content marketing. By understanding what your audience is searching for and why, you can create content that ranks, resonates, and drives results.
Remember:
-
Start with topics, not just terms
-
Focus on intent over volume
-
Use the right tools for deeper insights
-
Think of keywords as clues to audience needs
When your content is guided by solid keyword research, you’re not just guessing—you’re strategically building content that works.
