Expanded text ads have three headline fields. The first two headline fields are required, while the third is optional. The extra headline field allows you to include additional text in your ads. You can use up to 30 characters per headline. The headlines will appear next to each other, separated by a vertical pipe ("|"). Depending on the size of your potential customer’s screen, they may wrap to a second line. The third headline can appear more often on wide mobile devices.

Expanded text ads also have two 90-character description fields, giving you more control over your ad’s messaging.

The domain of your display URL is based on your final URL domain. Google Ads will use the domain from your final URL and show it as your ad’s display URL. For example, if your final URL is www.example.com/outdoor/hiking/shoes, your ad’s display URL will show as www.example.com.

The display URL can include two optional “Path” fields. You can combine your display URL with up to two new optional ”Path” fields. These fields are added to the display URL after your website’s domain, so you can add text that will help people who see your ad get a better sense of where they’ll be taken when they click it. The text you put in the path fields doesn’t necessarily have to be part of your website’s URL, but it should be related to the content on your landing page. So if your final URL is www.example.com/outdoor/hiking/shoes, you might want your path text to be “Hiking” and “Shoes” so your ad’s display URL is www.example.com/Hiking/Shoes.

Expanded text ads are mobile-optimized. A preview of your ad in both desktop and mobile format is generated for you while you’re creating your expanded text ad.
