Newcomer looking for advice

Hello, there. The company I work for assign me to a entirely new blog site and they won’t hire an SEO. It’s a website based on Wordpress and about e-cigarettes. We currently use the rank math plugin to manage things and all I do is follow the tips and ask advice from ChatGPT. I know the basics about SEO but still need to learn a lot. What’s your advice on Wordpress use or tools to start SEO or where to learn more about SEO?

We use Clicky, Ahref and GSC right now.
