What is SEO?

SEO (Search Engine Optimization) is the process of improving a website so that it appears higher in search engine results for relevant queries. The goal is to get organic (free) traffic instead of paid traffic.

SEO mainly focuses on three areas:

1. On-page SEO – optimizing content and HTML elements

2. Off-page SEO – building authority through links and mentions

3. Technical SEO – improving site structure and performance

To master these areas, you must first understand the language of SEO — the terminology.

Why SEO Terminology Matters

Learning SEO terms is important because:

• You can better understand SEO tutorials and tools

• You can communicate clearly with SEO agencies or freelancers

• You can diagnose website problems more easily

• You avoid common mistakes caused by misunderstanding concepts

Think of SEO terminology as the grammar of search engine optimization.
