Ad Extensions

Ad extensions (now commonly called ad assets) are additional elements that expand a search ad with extra information such as sitelinks, callouts, structured snippets, prices, phone numbers, and locations. Assets improve ad visibility and provide more entry points for users, which can raise click-through rate and improve auction performance. They do not replace strong ad copy, but they increase message depth and help users pre-qualify before clicking. Good asset strategy aligns each asset with campaign intent and landing page relevance. Performance should be reviewed by asset type and campaign objective, because not every extension improves conversion quality equally.
