Introduction to Keyword Research
Keywords are words or phrases people use to search for information online.
In this lesson, you will learn how to find and use the best keywords for SEO.
What Are Keywords?
Keywords help search engines understand what your content is about.
Types of keywords:
- Short-tail keywords: One or two words (e.g., 'Shoes').
- Long-tail keywords: Longer phrases (e.g., 'Best running shoes for beginners').
Long-tail keywords are more specific and easier to rank for.
Why Keyword Research Matters
Choosing the right keywords helps:
- Increase website traffic.
- Reach the right audience.
- Improve search rankings.
- Boost conversions and sales.
How to Find Keywords
Use keyword research tools to find popular search terms.
Popular tools include:
- Google Keyword Planner
- Ahrefs
- SEMrush
- Ubersuggest
These tools show keyword search volume, competition, and related terms.
Understanding Search Intent
Search intent is the reason behind a search.
Types of search intent:
- Informational: Looking for knowledge (e.g., 'How to bake a cake').
- Navigational: Searching for a specific website (e.g., 'Nike official site').
- Transactional: Ready to buy (e.g., 'Buy running shoes online').
- Commercial: Comparing options (e.g., 'Best laptops under $1000').
Where to Use Keywords
For better SEO, place keywords in:
- Page titles.
