What Is SEO?
SEO (Search Engine Optimization) is the process of optimizing your website to gain more organic (non-paid) traffic from search engines. It focuses on improving user experience, content quality, and technical performance so search engines can understand, index, and rank your pages effectively.
How Search Engines Work
Search engines follow three major steps:
1. Crawling
Search engine bots scan the web to discover new and updated pages.
2. Indexing
The discovered content is stored in Google’s index, making it eligible to appear in search results.
3. Ranking
Google ranks indexed pages based on relevance, content quality, authority, and user experience.
