You need to take this added step.
I’ve added a lot of domains I won in expired auctions to Uniregistry over the past few months. I added the names and changed the nameservers. Done, right? Wrong.
It turns out that adding domains to Uniregistry Market, even when you select the PPC lander, does not automatically add the “for sale” banner to the top of the page. Without this banner, visitors to the domain name have no way to submit an offer.
In order for this banner to be displayed, you have to add it after you submit your domains. There’s no default option to add this banner.
You can do it in bulk by selecting multiple domains and using the bulk tool.
This adds more steps to the process, so I hope Uniregistry makes this a default option in the future.
