Search engine optimization (SEO) is the practice of improving the visibility and ranking of web pages in organic (non-paid) search results. It involves aligning a site’s content, structure, and signals with what search engines consider relevant to user queries, with the aim of attracting higher-quality, sustainable traffic.

On-page SEO encompasses content optimization and technical factors. This includes meaningful titles and headers, natural keyword use, descriptive meta descriptions, well-structured headings, internal linking, and fast, mobile-friendly, accessible pages. Technical elements such as crawlability, structured data, sitemaps, canonicalization, and proper URL design also play a role.

Off-page SEO focuses on building authority and trust through high-quality backlinks, brand signals, and credible online presence. Content quality and relevance are central; search engines reward thorough, accurate content that matches user intent. Link-building remains a tactic, but links from reputable sources are more valuable than sheer volume.

SEO has evolved with major algorithm updates that favor user experience and content quality. Early practices like keyword stuffing gave way to emphasis on topics, intent, and semantic search. Modern systems use AI and machine learning to interpret queries, context, and user satisfaction.

Practitioners measure success with metrics such as organic traffic, rankings, click-through rate, and engagement metrics. Some indicators are proxies rather than direct ranking factors. Ethical, white-hat SEO emphasizes user value, while black-hat techniques risk penalties. The field continues to adapt to AI, voice search, and structured data.
