Thank you for reaching out, topical authority is an SEO concept of being the go-to authority on one or more topics so you could have your site be the topical authority on multiple coding languages.
We are unable to assist directly with this as you are the site publisher so the creation of content and the direction of your site does fall to you, however, we can try to help by giving you the tools and information to help you on your topical authority journey.
Firstly you need to establish yourself as a reliable source of information in a particular niche or subject area. Here are some steps that can help a website gain topical authority:
