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, shareable content to attract links from other sites 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 all employees to participate in content sharing and marketing.
