SEO ensures content reaches the right audience by improving visibility in search engines. Technical SEO focuses on site performance, mobile optimization, and fixing errors like broken links, ensuring search engines index content effectively. Off-page SEO involves earning backlinks from reputable sites to boost authority, while on-page SEO optimizes individual pages through structured content, strategic keywords, and compelling meta descriptions.

Backlinks serve as endorsements, boosting rankings and domain authority. High-quality links from trusted sources have a greater impact than a large quantity of low-quality links. Writing SEO-friendly content involves using keywords naturally in titles, headers, and descriptions while maintaining readability and value for the audience.
