LinkedIn's self-described native ads product, sponsored updates, accounted for about 43% of Marketing Solutions' revenue. LinkedIn hopes, by further integrating Bizo, it can provide lead nurturing tools "both on LinkedIn and off, on desktop and on mobile," said Sordello.
A new area for LinkedIn is long form content publishing, which it introduced last February and has accrued more than 1 million posts to date.
Whether long form content will open new inventory for LinkedIn or impact overall CPMs remains to be seen - it's still early days for the product, and the majority of LinkedIn inventory are sponsored updates, mostly on mobile.
LinkedIn also sees SlideShare, the content sharing platform the company acquired for $119 million in 2012, as a potential source of inventory and monetization for Marketing Solutions, since it has 70 million uniques.
LinkedIn says its differentiator from other consumer platforms and enterprise services is data and content.
"By virtue of our membership representing their identity to the world, we increasingly see those individuals sharing professionally relevant knowledge, which provides a strong in to somebody who wants a relationship with that prospect," said Sordello.
Understanding when someone switches a job, is promoted, or shares a piece of content are all important signals that can indicate messaging opportunities to sales or marketing organizations.
LinkedIn's overall user growth has been strong, increasing 25% year over year to 347 million members at the end of 2014. LinkedIn's executive team attributed the uptick in its user base to organic engagement and strong international growth.
