Google Ads extensions, which are now called “Assets”, are content pieces that make up your ad with useful business information- giving people more reasons to choose your business. It includes the headlines, descriptions, links to specific parts of your website, call buttons, location information, and more that come together to make up the eventual ad format, which is shown to a user. To maximize the performance of your responsive search ads, Google Ads selects additional assets to show in response to each individual search on Google. For that reason, it is a good idea to use all the assets relevant to business goals. By adding more content to your ad, assets like sitelinks and images give your ad greater visibility and prominence on the search results page. Assets often increase your total number of clicks, and can give people additional, interactive ways of reaching you as with maps or calls.
