LinkedIn Ads, the social network’s self-serve platform, has added video to its stable of options for B2B marketers. The company says the platform works seamlessly with YouTube, enabling advertisers to leverage their existing presence on the video site. Video ads will appear in standard 300×250 ad units across LinkedIn. “When a LinkedIn member is engaged and clicks your video ad, the video will take over the entire 300×250 ad unit and play a 30 second video,” the company explains in a blog post. “After the video completes, users will still be able to click through to your landing page or visit your website, just like with current ads.” (LinkedIn Marketing Solutions)
