Topical authority is the type of authority established by creating relevant, high-quality content.
The more informative, high-quality content you produce will increase the number of visitors who regard your website as an authoritative, trustworthy source on a particular topic.
Search engines consider various factors to determine topical authority, including content depth and quality, inbound links from other authoritative sites, and user engagement.
Above all, make sure your audience finds value in what you have to offer because they're the ones who will cement your reputation as a go-to source for information on your chosen topic.
