Complete your ad information. You can create multiple headlines and descriptions to be rendered in your responsive display ads. You can upload multiple versions of the following:

A short headline (at least 1, or up to 5 headlines, of 30 characters or fewer). The short headline is the first line of your ad (if you have not included promotional text for dynamic display ads). Short headlines may appear with or without your description. Learn more about responsive display ads best practices

A long headline (90 characters or fewer).

A description (at least 1, or up to 5 descriptions). The description adds to the headline and invites people to take action.

A business name. This is the name of your business or brand. Ensure your company name is spelled and capitalized correctly, as your ad will contain exactly what you provide.

A final URL. This is where people will go when they click on your ad.

Custom Banner Ads

Be sure to note the 150KB filesize limit. Files that are too large is the most common error we see when receiving these ads from designers. HTML5 and AMPHTML are the best formats, but can be expensive/difficult to create.
