One of the premises of the Growth-X product is that people trust people more than they trust companies. Nobody knows your target audience better than you. Therefore, it's important to understand exactly how LinkedIn's Search Features work.
You can search the Professional Network via location, position, and more. LinkedIn allows you different advanced filters that will make your campaigns much more targeted. The better you are at targeting your ideal audience, the higher your conversion rate will be.
The Ideal Audience Size of a given campaign is: 1,500 people.
Assuming you're sending 120 new invites per day, this will give your campaigns about 2 weeks of Juice.
After cycling through the first 100 pages of Search Results, the campaign will restart from Page 1 of Search Results.
