What is topical authority?
There’s literally 100’s of ranking factors, but often our focus is something called Topical Authority; a website’s expertise and credibility on a particular subject.
Google’s mission is to provide their users with the most relevant and reliable information available, so they analyse the depth, quality and quantity of content on every website, we call this topical authority.
This is the theory; your site won’t rank for a single post on a topic, but if you publish 25 posts, they all have an increased chance of ranking. Every topic is different; some may only need 10 posts, some might need 50 posts or more.
How do I know?
There’s tools available online, free and paid, that will build topical maps for you based on your keyword targets and what your competitors rank for. AI is also pretty good at statistical work, but this is still a little hit and miss.
