Responsive ads automatically adjust their size, appearance, and format to fit available ad spaces. So a single responsive ad may appear as a small text ad in one place and a large image ad in another.

• To create their ads, advertisers enter their assets (for example, headlines, descriptions, images, and logos). Then Google Ads automatically creates the ads people see.
• Responsive ads fit just about any ad space across the Display Network, and can take on native formatting to match the tone and feel of the websites they show on.
