Google Ad Extensions offer more advantages to your ad by including additional information. This gives consumers more reasons to choose your business over another. They often increase an ad's click-through-rate by 2 or more percentage points. Extension formats include visibly-rich call buttons, business location information, links to specific parts of your website, additional text, and more. Ad extensions are a type of ad format displaying extra information (extending from your text ads) about your business. These may be added manually and others are automated. Similar to higher ad positions, ad extensions provide your ad improved prominence on the search results page.
