Job placement ads are created by examining a users LinkedIn posts, homepage, groups and company pages.
According to LinkedIn director of product management Ryan Roslansky on the company’s official LinkedIn Blog:
The first is a recruitment ad that makes it easier for a job seeker to land a job by showing them people in their own personal network who could refer them directly.
This second ad example is from our self-service advertising solution called LinkedIn Ads. The ads show how public actions of your network, including product recommendations and the number of followers of that company, can help you decide whether or not you should take the time to learn more about the product or service. The personalized LinkedIn Ads will start rolling out Thursday to a small set of members as part of a limited release.
We’ve created this new layer of personalized content in ads with your privacy and trust in mind. Your name and image is never shared with any advertiser. Furthermore, you always maintain full control over your privacy settings on LinkedIn, and can opt out of these ads anytime. We’ll be rolling out these personalized ads in phases over the next few weeks and hope that they add valuable and actionable insights to your LinkedIn experience.
Here’s an example of how an ad may appear based on a users profile activity:
Notice how the ad actually finds your connections to a specific job offering to help you gain an upper hand on the thousands of applications many company’s receive for their positions. In this economy any extra help should be seen as a big positive and in that respect LinkedIn has moved in the right direction.
