Topic Authority

What is Topic Authority?

Topic Authority is a website’s subject-matter authority on a clearly defined topic, from the perspective of search engines. It is built through a combination of in-depth, cohesive content (topic clusters), internal links, topic-relevant backlinks, and a consistent expert presence over time. In 2026, Google will place greater emphasis on Topic Authority than ever before. At Waterproof Web Wizard, we build Topic Authority using content roadmaps: pillar pages, subpages, FAQ sections, all contributing to a single topic, rather than being a collection of random posts.
