Here are some general tips for niches.
A niche is something you feel super excited to write about, a skill you have attained, something that resonates with you. You will want to be focused on one niche. What is it that you want to help a group of people with or what problem do you want to help them solve (group could be age, gender, location, experience level, degree or type of need, etc.)

A niche is not a product, it's a subject that you can help a target audience with. Remember, you are not setting up a shop (store), you will be writing lots of articles about your niche to help your targeted audience.

The importance of a targeted audience is that It's always better to target a specific niche with a specific solution to problems.

Kyles asks us to complete this statement.
'i want to help ____(group) with ______(problem)'

For example. I like camping and what to help campers buy the right equipment to make their camping experience more pleasant and safe.

Camping is a very broad topic with a lot of competition so to eliminate some competition in the beginning so the website has a chance to grow, the focus needs to be a smaller scope. For example essential camping equipment for beginners. Once the website is established and has a good volume, its scope can be expanded to include other things camping related. This is just an example.

Hi

I would go with the face acne if it resonates with you and write lots of content addressing issues in relation to it.

The recommendation is to focus on ONE site starting out as it takes lots of effort and work get it going, however once you know what you are doing, then the learning curve would be less steeper to scale up.

You'd also want to narrow it down to a subcategory starting out, otherwise you will find it very hard to get noticed by the search engines and to compete with big authority sites. Target audience is important too, who would you be writing to, once you are able to identify them, you are closer to finding a focused niche.

Once a site starts gaining traction, traffic and authority you can then scale to cover another subcategory.

See example blog post below Succeeding With Golf Balls, Scaling With Shoes! A niche subject is something you are passionate and genuinely interested in could be a hobby or an interest, and know so well you can write plenty original content about.

ONE niche, a website. Products and programs can be varied however all must be relevant to the niche.

You may consult with https://answersocrates.com/ for further research into finding a subcategory starting out.
