What saas conversion rate benchmarks are considered good?

This is quite urgent as I'm launching apps back to back. I have some paid customers here and there and some OK traffic, but Im not sure what to pursue with more energy. What kind of conversion rates are considered "good" in order to pursue a product more seriously? When I say conversion rates I mean the following:

1. From landing page to app visit

2. From app visit to registration

3. From registration to paid customer

What numbers do you consider good? I haven't managed to find clear answers online.

PS: Im a solopreneur so I have limited resources, I cant be pursuing products that make no sense number-wise.

Cheeeeeers !
