Comprehensive Guide to Keyword Research for SEO: Strategies, Tools, and Best Practices

Introduction to Keyword Research

Keyword research (also called keyword analysis) finds the exact words people type into search engines. It guides every piece of web content. Solid key-phrase research helps pages rank higher and draw readers who want what you offer. Modern search engines value pages that match user intent—the reason behind each query. Good term research maps content to what people really want.
