About 8 years ago I started an SEO test to see how well the .media TLD would perform. I prepared the content, checked off all the seo best practices, had a solid link building strategy and ignored fezmedia.ca.
After running this test for 7 years, fezmedia.ca still had better search penetration so I closed down the experiment, setup all my 301 redirects and I’m focusing on fezmedia.ca again.
If you’re thinking of a newer TLD, it is possible to generate search traffic, but it’s not going to be a magic bullet.
