Intro to keyword research
📖 3 min readUpdated 2026-04-18
Keyword research is the process of finding the queries your audience types into search engines, prioritizing them by opportunity, and turning them into a content plan. It's the most valuable up-front SEO investment.
What keyword research tells you
- What your audience actually searches for (often different from what you'd guess)
- How much traffic each query could deliver
- How hard it is to rank for each query
- What intent is behind each query (informational, commercial, transactional, navigational)
- What content format is expected (guide, comparison, product page, video)
The workflow (high-level)
- Seed, start with 5-10 core topic seeds you already know about
- Expand, use tools (Ahrefs, SEMrush, Keyword Planner) to generate related queries
- Filter, drop low-volume, brand-dominated, and off-target queries
- Cluster, group related queries that should target the same page
- Prioritize, score by volume, difficulty, and business value
- Plan, assign clusters to content briefs
The three dimensions you're balancing
- Volume, how many people search it
- Difficulty, how hard to rank
- Value, how much a ranking conversion is worth
High volume + low difficulty + high value = win. Most real opportunities score well on two of three.
Common mistakes
- Optimizing for volume alone. High volume + low conversion value is a trap.
- Ignoring long-tail. Long-tail queries convert higher and are easier to rank.
- Treating every query as a new page. Many related queries belong on one page.
- Skipping intent. Ranking for the wrong intent = visitors bounce.
The deliverable
A good keyword research output is a spreadsheet with: cluster name, primary keyword, supporting keywords, volume, difficulty, intent, current ranking (if any), priority, and assigned page (new or existing).
