Rand Fishkin discusses the evolution of SEO and how search engines, algorithms, and user behavior have shifted in recent years. Some of the key changes include Google still dominating web searches but with declining organic click-through rates, the rise of intent-based optimization over keyword-focused strategies, and domains inheriting authority and semantic connections that help them rank for related queries. Successful sites are taking steps like developing brand authority in niche areas, prioritizing user intent in content and on-page optimization, and influencing searchers through listings and appearances in knowledge panels without requiring the user to click through to their site.
