AdWords advertisers have had advertising sitelinks at their disposal for quite some time and, by all accounts, they seem to work pretty well. According to Google, in fact, the click-through rate is 30 percent higher for advertisements with sitelinks than those without.
Sort of makes you want to run off to your AdWords account and set up sitelinks if you haven’t already, doesn’t it? Hold on one moment before you go, though – Google just enhanced those sitelinks and did so in a rather innovative way.
Google is now incorporating text from other ads in your AdWords account that are related to your sitelinks. So, for example, if you’re a pizza place and advertising your order page, a page profiling locations, and a page offering deals, those text ads will now appear as enhanced (extended) sitelinks with text descriptions instead of one-line hyperlinks.
To be eligible for the enhanced ad sitelinks, advertisers must have ads with sitelinks that show above Google search results (probably safe to assume that means in the first or second position) and accounts must contain active ads closely related to the sitelinks in the campaign.
