I have a website that was using the default domain from Vercel.
I tried creating a sitemap.xml and robots.txt file, but unfortunately, Google Search Console only recognized the homepage like this:
https://nameproject.omega.vercel.app
The problem is that I deleted the site from Google Search Console, but it still appears in search engines! When I click on it, the site no longer exists (404 error). I don’t care that it no longer exists, but it’s affecting my other website, for which I purchased a custom domain.
