This is an example but should I use: market.link or marketlink.com This would be from a branding perspective and I own both domain names so I can use either one. Tell me your opinion please!
.com is the king. Tell your mom or dad the xxxxx.link domain and ask them 2 days later about the name and they will tell you xxxxx.com
While this is true the new TLDs are going to become much more popular in a year or two. I would simply forward the .com to the .link and utilize both but start branding around .link.
It's the same name... the same letters...however you are considering dropping the 3 most important letters that 100% of the world associates with the internet and a domain name........ MarketLink.com for the win! You can use market.link but I wouldn't dare put it on a billboard because for most people it doesn't look like a domain. You might have people type in market.link.com. I also like mikebarbaro's idea with forwarding the .com to the .link. However, will Search Engines treat a .link with less importance? (I personally don't know.)
