Topical authority refers to how well a website is recognised as an expert on a specific subject. When a site consistently produces high-quality, relevant content about a specific topic, search engines see it as a trusted source and rank it higher in SERPs accordingly. To build topical authority, you need to cover a range of related topics in-depth, answer common questions, and provide valuable information that helps users find what they need.
