How to Measure Your Topical Authority Score Against Competitors
Topical authority determines who ranks for competitive queries. Here's how to quantify it and build a plan to improve it.
Topical authority is Google's assessment of how deeply and comprehensively your site covers a subject area. Sites with high topical authority rank more easily for new content within their established topics.
Measuring topical authority requires analyzing three signals: topic coverage breadth (what percentage of subtopics within a category do you have content for?), content depth per subtopic (word count, comprehensiveness, freshness), and external validation (backlinks from authoritative sources within the topic area).
