⭐ What Is Keyword Research?

Keyword research is the process of identifying and analyzing search terms people use in search engines, so you can target them in your content.
This is considered the foundation of SEO because it connects your content to real user questions and needs.

🎯 Why Keyword Research Matters

1. Helps your content match what people are actually searching for
2. Boosts visibility in search engine results (SERPs)
3. Increases organic traffic and conversion potential

SEO in 2026 emphasizes user intent, high‑quality content, and semantic signals—meaning keyword research is more about understanding audiences than stuffing keywords.

🧠 Understanding Search Intent

Search intent = the purpose behind a search query.
Aligning keywords with intent dramatically improves relevance and rankings.

Common search intents:

1. Informational – “how to optimize meta tags”
2. Navigational – “Semrush login”
3. Commercial – “best SEO tools 2026”
4. Transactional – “buy wireless headphones”

Intent is central to modern SEO.

🧩 Types of Keywords

Knowing the types of keywords helps you build a well‑balanced strategy.

1. Short‑tail Keywords

Broad terms, high volume, high competition
Example: “SEO tips”

2. Long‑tail Keywords

More specific, lower competition, higher intent
Example: “local SEO strategies for restaurants”

3. Intent‑driven Keywords

Matched to the user’s goal (info, buy, compare)

4. LSI / Semantic Keywords

Related concepts that help search engines understand content
Example for “content audit”:
“on‑page SEO,” “crawl errors,” “site structure”
