What Is Keyword Research?
- Keyword research is the practice of identifying the exact phrases and words your target audience types into search engines.
- It tells you what topics people care about, how often they search, and how hard it is to rank for each term.
- Done correctly, it's the foundation that every other SEO decision — content, structure, backlinks — should be built on.

The 5-Step Process
Brainstorm Seed Topics
Start from your niche. Consider the problems your audience faces. If you run an SEO blog, your seeds might be "on-page SEO", "technical SEO", "backlinks". These are the roots from which your keyword tree grows.
Use Keyword Research Tools
Expand your seeds using tools that return search volume, keyword difficulty, and competitor data. Each tool has different strengths — use at least one for research.
Determine Search Intent
Ask: what does the user actually want? Match your content type to the intent. "best SEO tools" → commercial intent, write a comparison post. "how SEO works" → informational intent, write an explainer.
Analyze the Competition
Search your target keyword in Google. Study what ranks on page one — content depth, structure, word count, and angle. Tools like Ahrefs can show backlink counts for each result.
Prioritize Low-Competition Keywords
For new or small sites, target keywords with low Keyword Difficulty (KD) and medium search volume. Avoid chasing "SEO" — go for "SEO tips for small blogs" instead.
Search intent is the single most misunderstood concept in keyword research. Matching your content format to the intent type matters more than keyword density. Google rewards pages that truly satisfy what the searcher was looking for.
Key Metrics Explained
| Metric | What It Measures | What to Look For |
|---|---|---|
| Search Volume | Average monthly searches for the keyword | Medium volume (500–10K) is often the sweet spot for new sites |
| Keyword Difficulty (KD) | How hard it is to rank on page one | Aim for KD under 40 when starting out; under 20 for very new sites |
| CPC (Cost Per Click) | How much advertisers pay per click in Google Ads | High CPC = high commercial value; great signal for monetizable content |
| Trend | Whether interest in the keyword is growing or declining | Target rising trends early for first-mover advantage |
On-Page Keyword Placement
Once you have your target keyword, place it in these critical on-page locations to signal relevance to search engines:
Pro Tips
- Prioritize long-tail keywords — they convert better and are far easier to rank for when starting out.
- Use question-based keywords — phrases starting with "how", "what", or "why" match informational intent and often trigger featured snippets.
- Include local keywords — if you serve a specific area, add the location to your keywords (e.g. "SEO agency in Kathmandu").
- Refresh keywords regularly — search trends shift. Revisit your keyword strategy every 3–6 months.
- Use LSI keywords — Latent Semantic Indexing keywords are semantically related terms that help Google understand context and depth.
Real Example: SEO Blog
- "best SEO tools 2026" — commercial
- "free SEO tools for beginners" — informational
- "SEO tools for blog writing" — commercial
- "technical SEO tools list" — informational
Do's & Don'ts
- Target long-tail keywords first
