Google AdWords has been rolling out new ways for advertisers to use Ad Extensions — from its recent launch of Social Extensions from Google+, to tried and true Sitelinks that give advertisers more innovative ways to link to their website from their AdWords ads.
Most recently, I have seen ads that Google is calling a “Mega Ad Sitelinks Experiment”. It looks like there are three ads, but all three ads are tied to one advertiser:
Google says that Mega Ad Sitelinks is currently in beta and will only appear when there is only one top ad. Google adds that it is happening to current ads that have Sitelinks already implemented and is predicted to increase click-through rate (CTR).
The Mega Ad Sitelinks ad takes up a majority of real estate on the search engine results page (SERP) and also gives searchers more detailed and specific links. In the example above, the top ad includes information on generic jeep parts, whereas the bottom two ads include ad copy that is specific to jeep softtops and tire carriers for jeeps.
Google AdWords currently also offers the following Sitelinks options: Location, Call and Product Extensions. For more information on AdWords Sitelinks, visit the AdWords Help Center.
