Search Engine Optimization (SEO) is the process of optimizing a website to improve its visibility and rankings on search engine results pages (SERPs). In simple terms, SEO helps websites appear higher in organic (non-paid) search results when users search for relevant keywords or phrases on search engines like Google, Bing, or Yahoo.

### How SEO Works:

This includes optimizing meta titles, descriptions, headers, and content with relevant keywords, improving website speed and performance, optimizing images and multimedia, and ensuring mobile-friendliness and responsive design.

3. **Off-Page Optimization:** Off-page SEO refers to activities conducted outside of a website to improve its search engine rankings. This includes building high-quality backlinks from reputable websites, promoting content on social media and other platforms, and enhancing online reputation and credibility through positive reviews and mentions.

4. **Technical SEO:** Technical SEO focuses on optimizing the technical aspects of a website to improve its search engine visibility. This includes optimizing website structure and navigation, implementing schema markup to enhance search engine understanding of website content, improving website speed and performance, and ensuring proper indexing and crawlability.
