Enhanced sitelinks introduced, adding two lines of description text under each sitelink

Ads in the top positions became eligible for an expanded sitelinks format that shows descriptive text beneath each link, drawn from existing ads in the account that closely match the sitelink's landing page. No new setup was required; eligibility depends on having ads relevant to each sitelink. Google cited a roughly 30% higher click-through rate for ads with sitelinks versus those without.
