Monetization is the key factor, how you do it, value of audience, value of content. I had a site that was getting around 100 to 400 visits a day and making ~40k a month. It just depends on what its about.
I would recommend find something you are passionate about, something you LOVE to learn about and write about. Then start looking at how you could monetize it to get a side gig up. As there are a lot of very popular sites with a ton of traffic that don't make much money because the audience is not worth anything.
I am happy to brainstorm if you have any ideas for topics you like and how to monetize it past just ads.
