Google is back at it again with the mobile AdWords sitelink testing. Last time, we spotted a card like layout with a link to the website at the end. Today, Google is testing another version of this sitelink format.
In this test, the sitelinks are more narrow and compact compared to the previous test, but perhaps that is because of the triple-stacked location extensions that Google is showing here as well. It does seem that a new version of mobile sitelinks may be rolling out soon as Google continues to test this particular element of the SERP.
