Setting up your LinkedIn Ads account is simple. To start you’ll need a LinkedIn account and a credit card. Begin by logging into your LinkedIn account here. Once you’re logged in, click the “Advertise” link at the bottom of the page (if the page just keeps scrolling and scrolling, just go to http://www.linkedin.com/advertising )
Once you’ve arrived, click the big yellow “Start Now” button.
Follow the steps and SHAZAM! You’re now a full-fledged LinkedIn advertiser.
