A common question is what you can use a mobile-specific display URL for? The varying options are usually:
1. Indicate that you have a mobile-friendly landing page
2. Differentiate yourself from other advertisers
3. Show consumers that you are a large brand
4. Effectively track conversions to your desktop site
The correct answer would be 1, which would be to show that your site has a mobile-friendly landing page. This is especially effective when participating in mobile advertising campaigns, especially on social media platforms. Many mobile users will refuse to click on a link if the page isn’t optimized for mobile, simply because the experience will be frustrating.
