In October of 2008, Oprah Winfrey shared Amazon’s new Kindle eBook reader with her audience. "It's absolutely my new favorite thing in the world," she said. Amazon’s visits were up 6 percent the day Oprah endorsed Kindle on her show, over the previous Friday. Being endorsed by Oprah is so powerful that it became known as the Oprah effect.

Then in July of 2014, an unknown author named Edan Lepucki debuted her novel, California. Late-night television host Stephen Colbert began attacking Amazon for discouraging customers from buying titles from his publisher, Hachette Book Group. But Mr. Colbert picked another Hachette author — a startled Ms. Lepucki — as the focal point of his campaign against Amazon. He challenged viewers to buy enough copies to get the novel on the New York Times best-seller list. The book became one of the most preordered debut titles in Hachette history and did in fact become a New York Times best-seller.

These stories show what can happen when someone else endorses and promotes your products and services. In his book, Greg Jameson calls this "The Influencer Effect". 

How can the average business owner, who doesn’t have the budget for a celebrity endorsement, create this type of success for their company? There is a replicable process called GEARS, that Jameson describes in his book. As it turns out, celebrities are not always the best type of influencer. Lesser-known experts can often have a bigger impact on their following, much like a referral from a close friend or family member. These people are known as micro-influencers and your business will improve by working with them.

Using both personal stories and those of his clients, this book provides real-world examples on how you can grow your influence. The GEARS acronym is used to explain the process in a clear and easy-to-remember system that anyone can apply. The parts of this gear system are as follows:

The center gear is called a "sun" gear. Everything revolves around the sun gear, which includes strategy and execution. The three gears that circle the sun gear are the "planet gears". These gears, "G, E, and A" comprise the primary methods used to develop a following, and how to market your online business. They stand for "Generate interest", "Empower influencers", and "Amplify your message".

The outer gear is called a "ring gear". This gear encircles all the other gears. This is discussed in the section on "Results", which is divided into three chapters: Revenues, Review and Repeat, and Research.

Influence is simply about getting others to take a desired action. Jameson encourages the listener to not be selective with the methods he describes by following the GEARS system, but to use them all. When you do, the results can be massive.
