When it comes to SEO, topical authority is often thought of as one of the most important ranking factors because whenever someone searches for something on the internet, they are looking for the most trustworthy results. Topical authority essentially measures how relevant and trustworthy a website is on a given topic. In other words, it is a reflection of how well a website covers a specific topic.
There are a number of ways to measure topical authority, but one of the most common is through inbound links. In general, websites with more inbound links from high-quality websites are considered to have more topical authority. Additionally, topical authority can also be measured by looking at the overall content of a website. Websites with high-quality and updated content are often considered to be more authoritative on their respective topics. Meeting all of these criteria helps a website build up its topical authority and climb to the top of the search engine results pages.
