Keyword research

Definition

Keyword research is the practice of identifying and analyzing search terms that users enter into search engines when looking for information, products, or services. It provides insights into audience behavior, showing what topics matter most to potential customers. By selecting and targeting the right keywords, businesses can optimize their content, improve visibility, and attract qualified website traffic.

This process is foundational in SEO, content marketing, and paid advertising. It ensures that websites and campaigns match the language and intent of users rather than relying on assumptions. For example, a company selling athletic shoes may find that people search more often for “running sneakers” than “athletic footwear,” guiding how product pages and ads should be structured.

Advanced

Advanced keyword research involves more than identifying popular search terms. It requires understanding search intent, clustering keywords into topics, and analyzing competition. Marketers examine metrics such as keyword difficulty, click-through potential, and seasonality trends to prioritize opportunities.

Techniques include semantic keyword mapping, competitor gap analysis, and use of AI-driven tools to uncover long-tail and voice search phrases. Businesses may also apply latent semantic indexing (LSI) terms to support natural language queries. Keyword research is increasingly integrated with SERP analysis to identify opportunities for featured snippets, local packs, and other search result enhancements.

Use cases

• Optimizing website content to rank for strategic terms.
• Building PPC campaigns that capture high-converting searches.
• Creating blog posts or articles that match user intent.
• Uncovering new product or service opportunities based on keyword data.

Metrics

• Search volume for each keyword.
• Keyword difficulty or competitiveness.
• Click-through rates from search listings.
• Conversion rates of traffic from targeted keywords.

Example

An online fitness store discovers through keyword research that "adjustable dumbbells for home workouts" has strong purchase intent but moderate competition. By optimizing product pages and running targeted ads for this term, the store sees higher conversions and lower cost per acquisition compared to targeting broad keywords like "dumbbells."
