Many SEO blogs mentioned that the new generic TLDs were better than .com, .org, .net, .info
This is wrong and Google debunked this idea several times. The new generic TLDs don’t rank better in google search results because of their domain TLD.
First of all, Matt Cutts from Google debunked this idea back in 2012.
I read a post by someone offering new top-level domain (TLDs). They made this claim: “Will a new TLD web address automatically be favoured by Google over a .com equivalent? Quite simply, yes it will.”
Response from Matt Cutts:
Sorry, but that’s just not true, and as an engineer in the search quality team at Google, I feel the need to debunk this misconception. Google has a lot of experience in returning relevant web pages, regardless of the top-level domain (TLD). Google will attempt to rank new TLDs appropriately, but I don’t expect a new TLD to get any kind of initial preference over .com, and I wouldn’t bet on that happening in the long-term either. If you want to register an entirely new TLD for other reasons, that’s your choice, but you shouldn’t register a TLD in the mistaken belief that you’ll get some sort of boost in search engine rankings.
Then, once again in 2015, John Mueller from Google mentioned that new generic TLDs didn’t rank better than .COM
Q: How will new gTLDs affect search? Is Google changing the search algorithm to favor these TLDs? How important are they really in search?
A: Overall, our systems treat new gTLDs like other gTLDs (like .com & .org). Keywords in a TLD do not give any advantage or disadvantage in search.
Q: Will a .BRAND TLD be given any more or less weight than a .com?
A: No. Those TLDs will be treated the same as a other gTLDs. They will require the same geotargeting settings and configuration, and they won’t have more weight or influence in the way we crawl, index, or rank URLs.
