> the top comment suggests the they are SEO black holes.
The top comment in question reads like a Trump tweet and provides no further details, no sources, and no data:
"I have said it before and I will say it again, the new gTLDs are just a money grab by ICANN. Not only that, but they are basically SEO black holes, no thanks!"
Until someone definitely proves that new TLDs are detrimental to SEO, I'm not buying it. Much likelier is that the domains built on new TLDs simply don't have the domain age or link profile of competitors whose domains have been around for years and years.
