Earlier this month, diTii.com reported that Google is testing domain names in AdWords ads. It's official now, Google just announced they'll now automatically show display URL domain in the headline for select top placement ads on Google. This's a global launch that affects all countries and languages.
"As a result, your brand will be featured more prominently in your ad, and you can use the text in the headline to highlight other information. Potential customers, on the other hand, will be able to more easily identify the site to which they'll be taken after they click on your ad," Google stated.
"When shown in the headline, the display URL will be separated from the rest of the text by a vertical bar and will include only the domain, not the "www." prefix or any subdirectories. Your display URL will also continue to appear as normal below the description line. Of course, if the headline already contains your domain, we won't display it again," Google added.
Finally, it's possible for the display URL domain to appear in addition to a description line that's promoted to the headline, as long as the resulting headline is sixty-eight characters or less.
