Some users saw only the domain name during a test.
The full URL has won, at least for now.
The thinking behind the test was that users who only saw the domain name and not the entire URL would pay more attention to the domain and consider if the site was suspect.
But the experiment didn’t pan out as theorized. Google has ended the experiment because the company says it didn’t have a meaningful impact.
This battle is won, but you can expect more assaults on URLs in the future. Google says URLs “kind of suck.”
