Back in 2012, Google's Matt Cutts said clearly that new TLDs do not rank better than any other TLD. He was killing a myth being spread by some domain name sellers.

Google's John Mueller felt the need to reshare this old post from Matt this weekend on Google+ saying "It feels like it's time to reshare this again."

He said, "there still is no inherent ranking advantage to using the new TLDs."

I guess he is reading domainers trying to up the TLDs, those new ones, again. John went on to expand on this:

They can perform well in search, just like any other TLD can perform well in search. They give you an opportunity to pick a name that better matches your web-presence. If you see posts claiming that early data suggests they're doing well, keep in mind that's this is not due to any artificial advantage in search: you can make a fantastic website that performs well in search on any TLD.

So don't be fooled!
