What Is SEO?
SEO (Search Engine Optimization) is the process of optimizing websites to improve their visibility on search engines like Google. The goal of SEO is to attract organic traffic by ranking higher for relevant keywords.
In digital marketing, SEO helps connect user searches with useful content. Instead of relying on paid ads, SEO focuses on building long-term visibility through quality content, optimized pages, and strong website structure.
Simply put, SEO ensures that a website appears when users search for related information.
How Search Engines Work
To understand how SEO works, it is important to understand how search engines function.
Crawling
Search engines use automated bots to discover web pages. These bots scan websites, links, images, and content across the internet.
Indexing
After crawling, pages are stored in a database known as the search index. Only indexed pages are eligible to appear in search results.
Ranking
When a user searches, the search engine ranks indexed pages based on relevance, quality, authority, and user experience.
SEO improves how a website performs at each of these stages.
Types of SEO
SEO is divided into three major types, each focusing on different aspects of optimization.
On-Page SEO
On-page SEO involves optimizing content and page elements such as:
