Introduction
Search engines are becoming better at understanding topics instead of focusing only on individual keywords. This change has made topical authority one of the most important SEO strategies for websites that want long-term growth.
Building topical authority means proving that your website is a reliable source of information about a specific subject.
In this guide, we will explore how topical authority works and how to build it using a strategic keyword approach.
