Chief among LinkedIn's new b2b advertising products is "LinkedIn Lead Accelerator," which allows brands to place a pixel on their websites, which uses cookies to identify LinkedIn users so advertisers can get a better understanding as to the types of people visiting. LinkedIn says that currently, most website owners only actually know about 5% of their visitors, and that LinkedIn Lead Accelerator fills in that gap. The data is all anonymized: Advertisers won't know you visited their website, but they will know that 30% of their visitors are finance directors from London, for example. Users can opt out of this form of targeting via their LinkedIn settings.
