Technical Definition
Topical authority is the perceived expertise a website has on a subject based on comprehensive, quality coverage. Built through: topic clusters, internal linking, expert content, consistent publication. Helps rank for competitive terms without excessive link building. Related to E-E-A-T. Signals depth of knowledge to search engines and AI.
Simple Explanation (ELI13)
Topical authority is when Google sees your site as an expert on a subject because you've covered it thoroughly and well. If you have 50 great articles about running shoes, you have more topical authority on that topic than a site with one article. It helps you rank without needing as many backlinks.
