🔑Keyword Research Fundamentals
How to find keywords your target audience actually searches for — covering search volume, keyword difficulty, search intent alignment, and how to build a keyword map.
Keyword research is the process of discovering what words and phrases your target audience uses in search engines. Without it, you're guessing what content to create. With it, you create content with built-in demand.
Key Metrics to Evaluate
| Metric | What It Tells You | Good Starting Point |
|---|---|---|
| Search Volume | How many monthly searches | 100–1,000/mo for new sites; higher for established ones |
| Keyword Difficulty (KD) | How hard to rank (0-100) | < 30 for new sites; can target higher as you build authority |
| Click-Through Rate % | How many searchers click results | High for informational; low for featured snippet dominated queries |
| Cost Per Click (CPC) | What advertisers pay | High CPC = commercial intent = buyer-ready audience |
Head Terms vs Long-Tail Keywords
Head terms are short, broad keywords ("SEO checker") with high volume and high competition. Long-tail keywords are specific, multi-word phrases ("free SEO checker for small business websites") with lower volume but lower competition and higher conversion intent. New sites should focus on long-tail keywords.
Long-tail keywords (3+ words) account for 70% of all search volume. While each individual long-tail query has low volume, collectively they represent the majority of searches — and they're far easier to rank for.
Keyword Research Process
- Seed keywords: List 10-20 broad terms related to your business.
- Expand: Use a tool (Ahrefs, SEMrush, Google Keyword Planner, Ubersuggest) to generate related terms.
- Filter: Remove irrelevant terms, high-difficulty terms beyond your current authority.
- Classify by intent: group into informational, commercial, transactional, navigational.
- Map to pages: Assign each keyword (or cluster of related keywords) to a specific page.
- Prioritize: Focus on keywords that align intent with your current content and authority level.
Keyword Mapping
Keyword mapping means assigning specific keywords to specific pages on your site. Each page should target one primary keyword and several secondary keywords. Never target the same primary keyword on multiple pages — this creates "keyword cannibalization" where your own pages compete against each other.
