What ad formats can be used in a Google Search ads campaign?

Google Search ads primarily use text-based ad formats. The most common ad formats for Google Search ads include:

1. Expanded Text Ads (ETA): These ads allow advertisers to create longer ad headlines and descriptions, providing more space to convey their message. Expanded Text Ads typically consist of three headlines and two description lines.
2. Responsive Search Ads (RSA): RSA allows advertisers to create multiple headlines and descriptions, and Google’s algorithm dynamically assembles different combinations to find the most effective ones. Advertisers can provide up to 15 headlines and 4 descriptions.
3. Call-Only Ads: These ads are designed specifically for mobile devices and encourage users to call the advertiser directly by clicking on the phone number in the ad.
4. Dynamic Search Ads (DSA): DSA dynamically generates ad headlines and landing page URLs based on the content of your website. Advertisers provide a description, and Google matches user queries to your website.

Please note that Google may introduce new ad formats or make changes to existing ones over time, so it’s advisable to check Google Ads documentation or the Google Ads platform for the most up-to-date information on available ad formats.
