LinkedIn is woring on a new 'Lookalike Audience' feature. This feature will allow advertisers to target users who seem similar to their current customers.
It has recently introduced many new features including Carousel Ads, Interest Targeting and Sponsored videos. Seeing Facebook Ads, the Lookalike audience targeting has always been a very important feature.
Advertising on LinkedIn will be expensive when compared to Facebook. On LinkedIn there is a chance that you can include the job title which is not possible when on Facebook.
