SEO has evolved significantly over time from focusing solely on on-page context to also considering off-page authority and now personalization. Early SEO involved stuffing keywords and optimizing individual pages. Later, the focus shifted to creating high-quality, link-worthy content to build authority. Now, search results are highly personalized based on user history, social connections, and real-time information. To succeed at SEO today, companies must publish content across multiple channels, build large social followings, engage those followers, and empower employees to participate in content sharing and discussions online.
