The guide, How to Network in the Masses, will be given to delegates attending the forum3 charity recruitment event in north London this week to help them make the most of the conference.
An estimated 15,000 people will attend the event, which starts on Friday.
Tips in the guide, produced by recruitment agency People Unlimited, include rehearsing a 60-second introduction that sounds natural, being genuine and authentic, and setting aside time to follow up with the people you have met.
Deborah Hockam, director of forum3, said: "For some people, speaking to someone they don't know can be terrifying and networking does not come naturally to everyone. We have created this guide to help overcome any fears and make those who are already good at networking even better."
