Search Engine Optimization (SEO) is the practice of optimizing websites, content, and online presence to improve visibility and ranking on search engine results pages (SERPs). The goal of SEO is to attract organic (non-paid) traffic from search engines like Google, Bing, and Yahoo by aligning with their algorithms and user intent. Here’s a detailed breakdown of SEO:
Core Objectives of SEO
-
Increase Organic Traffic: Drive more visitors to a website without paid advertising.

How Search Engines Work
Search engines use automated bots (crawlers or spiders) to:
-
Crawl: Discover and scan web pages.
-
Index: Store and organize content in a massive database.

SEO focuses on ensuring that a website is easily crawled, indexed, and ranked favorably.
