1. Understand Keyword Intent: The “Why” Behind Every Search
Before you dig into any tool, you need to understand keyword intent.
Keyword intent tells you what the searcher wants to do:
- Are they looking for information?
- Are they comparing products?
- Are they ready to buy?
There are three core types of intent:
✅ Informational:
People want answers, advice, or education.
Examples: “how to train a puppy,” “best time to visit Italy.”
→ Use for blog posts, tutorials, or guides.
✅ Commercial / Investigational:
People are researching before buying.
Examples: “best noise-canceling headphones,” “Grammarly vs Hemingway.”
→ Use for product roundups, reviews, comparisons.
✅ Transactional:
People are ready to take action or buy.
Examples: “buy running shoes online,” “cheap web hosting discount.”
→ Use for landing pages, product reviews with clear CTAs.
Pro tip: Build a mix of content for all three intents to guide readers along the full buyer journey.

Instead of “coffee maker,” aim for “best single-serve coffee maker for small kitchen.”
4. Competitor Gap Analysis: Spy and Thrive
Why guess when you can borrow ideas from competitors?
Competitor gap analysis helps you:
- Find keywords competitors rank for
- Identify gaps you can fill
- Discover low-hanging opportunities
How to do it:
- Identify top competitors (use Google or Ahrefs’ Site Explorer).
- Plug their domain into Ahrefs, Ubersuggest, or SEMrush.
- Analyze:
- What keywords bring them the most traffic?
- Which pages rank for those keywords?
- Where are they weak or missing content?
Pro tip: Don’t just copy improve. Look at their content, then ask:
- Can I cover this better?
- Can I add data, images, or video?
- Can I answer related questions they missed?
5. Map Keywords to the Right Content Types
Throwing all your keywords into random posts is like tossing spaghetti at the wall.
Instead, map each keyword to the right type of content:
✅ Informational Keywords → Blog posts, guides, tutorials
- Example: “how to speed up WordPress site”
✅ Commercial Keywords → Product roundups, comparisons, listicles
- Example: “best budget laptops for students 2025”
✅ Transactional Keywords → Product reviews, landing pages, email CTAs
- Example: “buy MacBook Air online cheap”
Bonus tip: Create content clusters link related posts together to boost SEO.
- Example:
- Pillar page: Best home espresso machines
- Supporting posts: Espresso machine reviews, cleaning tips, accessories guide
