LinkedIn ad specs

1. LinkedIn sponsored content Back to top

Sponsored content allows you to share content to Linkedin members beyond those who are following your company. It appears on users feeds mixed with other content their connections shared. This is what we call native advertising — when an ad looks like an average person’s post with images, text, and so on. The one distinction is that it is labeled as sponsored content so as not to be deceiving to those reading it.

You can add Linkedin Lead Gen Forms to your sponsored content to display a call to action button to collect qualified leads from people who read your content (see image above). Let's suppose you are using Linkedin Sponsored Content to promote an event. With Lead Gen Forms you can invite people interested in your event to sign up through a form on Linkedin to receive tickets.
