Spotted by James Carswell, Google is testing a new form of an AdWords ad that shows the number of job openings available on the landing page.
It appears that this might be a new AdWords extension specifically designed for job opening and job search sites. Here is a picture from James:
As you can see, the ad has an extra link that contains the number of job openings available on the landing page and the name of the site.
In the Search Engine Watch Forums thread Rod Hull said:
Interestingly, in that case only 1 of the 3 ads showed the extra line. The other 2 ads in the banner position already mentioned job numbers in the actual ad description, so this may be the reason for Google not showing the extra line in that case.
I cannot reproduce this type of ad, but it would not surprise me if we will soon see a new AdWords extension for jobs.
