What is Search Engine Optimization (SEO)?

Search Engine Optimization (SEO) is the systematic practice of improving website visibility and ranking in organic (unpaid) search engine results pages (SERPs). It involves optimizing content, technical infrastructure, user experience, and authority signals so search engines view the site as relevant, trustworthy, and valuable.

SEO includes on-page elements such as content, keywords, titles, and page structure, technical aspects like site speed and mobile optimization, and off-page signals such as backlinks and brand mentions.

Unlike paid advertising that provides instant but temporary visibility, SEO builds sustainable organic traffic over time through earned rankings and continuous optimization.

• It attracts highly relevant visitors searching for specific products, services, or information.
• Higher rankings build trust and credibility among users.
