What Is Topic Authority (And Why It’s Your SEO Superpower)
Topic authority refers to your website’s perceived depth and credibility in a particular niche. Google rewards sites that consistently publish high-quality, interlinked, and strategically structured content around a central theme. Instead of being a generalist, you build expertise in one area, which signals trustworthiness to both users and algorithms. Imagine being the go-to source for a specific topic—search engines will rank your content higher, driving more targeted organic traffic.
