You're asking the right questions. Keep researching, studying successful domain sales, and improving your portfolio. That's how most successful domain investors get started.
Welcome to the domain community! I remember how confusing everything felt when I listed my first domain. Don't worry if you don't get offers right away—patience is a big part of this business.
One thing I'd recommend is checking recent sales of similar domains before setting your asking price. It can help you avoid pricing them too high or too low.
I made the mistake of listing my first domains on only one marketplace. Once I expanded to a few different platforms, I started getting a lot more views and inquiries.
Don't get discouraged if nobody contacts you in the first few months. Some of my best domain sales happened after the domains had been listed for over a year
I like that you're asking for feedback instead of assuming the names are valuable. That's the right attitude if you're serious about learning domain investing.
I would also look at Afternic if you haven't already. Having your domains visible across multiple registrar networks can increase your chances of a sale.
My first portfolio was full of names I thought were amazing. Looking back now, I realize I learned much more from the ones that didn't sell than the ones that did.
