Hey there, Johnny! Please don't hesitate to share your experiences here in the forum. With your background, I'm sure many domainers will learn a lot from you. :)
I have 235 names listed and only 2 sales so far. Started in May 2019 and stopped listing in September. Not far off from the generally-accepted 1% STR but definitely lower than the SH average (which was the reason why I tried the platform). Hopefully sales come in before renewals. :xf.frown:
It's not ideal but it's inevitable. To be fair, SH still has the fastest review time among the brandable marketplaces. I'm still waiting for my first sale though. I'm close to 200 names already. Hopefully next month!
Well don't buy domains until you're sure that you know how to find a good name. :)
Just read, read, and read.
