Search Engine Optimization (SEO) is the practice of enhancing a website’s visibility on search engines like Google. It involves optimizing content, improving site structure, and using keywords effectively to attract organic traffic. Key components include on-page SEO, which focuses on elements like titles, meta descriptions, and internal linking, and off-page SEO, which involves building backlinks and promoting content. Technical SEO also plays a crucial role, ensuring the website is fast, mobile-friendly, and easily crawlable by search engines. A well-executed SEO strategy can significantly increase a site’s ranking, drive more visitors, and ultimately boost conversions and revenue.
