What kind of website/blog can I set up to practice SEO in 2024?

I have a question about SEO and setting up a website to expand my skill set as a content writer. In the past, setting up a website and blogging about familiar topics was common, but with new Google updates and emphasis on EEAT, I'm not sure if that's still the best approach. I would like to blog about mental health, but as I'm not a professional in that field, I'm concerned about potential consequences from Google. I also write about tech niches and have a background in computer science. Should I focus on blogging about these niches instead, or am I overthinking this?

Focusing on tech niches with your background in computer science could be a good approach for practicing SEO in 2024. While blogging about mental health is a worthy cause, the potential risks of providing information without proper qualifications might be too high. Google’s focus on EEAT (Expertise, Experience, Authoritativeness, Trustworthiness) means that content needs to be produced by credible sources. By sticking to tech niches, you can leverage your existing knowledge and expertise, leading to more authoritative content that aligns with Google’s guidelines. This approach allows you to practice SEO techniques without the added concerns about providing potentially harmful information.
