What are some realistic ways to make a little money online?

I have reliable internet access and I’m looking for realistic ways to make a bit of money online.

I’m not trying to make $1,000 a month or anything like that. Even making $10 here, $20 there, or $30 occasionally would be useful to me.

I’ve tried Fiverr, but I haven’t been able to get any gigs. It’s possible I’m setting up my services/profile wrong, so I’m open to advice on that too.

For people who actually make small amounts of money online, what methods would you recommend? Ideally things that don’t require a lot of money upfront and that someone can start learning/doing with just a computer and internet connection.

I’m happy to do simple, repetitive, or beginner-level work. I’m mainly looking for legitimate options, not surveys that pay a few cents or anything involving scams/crypto/gambling.

What has actually worked for you?
