In the early days of SEO, authority was a crude concept. In the early 2000s, ranking well often came down to how effectively you could game PageRank. Buy enough links, repeat the right keywords, and visibility followed. It was mechanical, transactional, and remarkably easy to manipulate. Two decades later, that version of search is largely extinct. Algorithms have matured. So has Google’s understanding of brands, people, and real-world reputation.
