Affiliate marketing is a much-coveted career path in the business of online moneymaking. After all, it’s convenient, it looks easy enough and everybody’s doing it. But make no mistake: it’s a virtual jungle out there.

On various stages of their involvement with the affiliate marketing channel, merchants look in the direction of launching affiliate programs for the same products on multiple networks. The most common reasoning for this being that by so doing they will expand their affiliate reach, significantly improving chances of recruiting powerful affiliates across different networks.

Top interactive agencies and affiliates share their tricks for picking the right ad network.

Conservatively estimated, there are upwards of 400 ad networks globally. There is a Japanese iPhone-only ad network and the recently launched Village Voice alternative weekly New York newspaper ad network – and everything in between. For ad agencies representing top brands, and for affiliates trying to make a living in the increasingly competitive world of performance marketing, picking the right one is critical to survival. Choosing poorly spells disaster for everyone.

Whether it is for spring to begin, for Godot or for a commission check, no one likes waiting.

The 30 to 90 days that affiliates – especially those outside the U.S. – must wait for commission checks to arrive can seem like a lifetime, and waiting in line at the bank to cash it is so 20th century.

When Brent Elias began working at CSN Stores.com in 2002, the Boston-based online home furnishings retailer didn't have an affiliate program. Elias began his career at CSN working in the advertising department on the keywords team. Like many e-tailers, CSN Stores was afraid that affiliate marketing would cannibalize sales from its main online store.

Linda Woods, CEO of PartnerCentric, an outsourced affiliate program management group, says that affiliate recruitment is the hardest thing affiliate managers have to do.

"There is no software that spits the names of affiliates out," she says, adding that there is no easy way around the arduous process of finding, meeting and building a relationship with the appropriate affiliates.

In the May/June Affiliate's Corner column, I wrote about the ways super-affiliates prefer to be approached by affiliate program managers and merchants for the purpose of program recruitment.

Wooing a super-affiliate over drinks and dinner with offers of exclusive landing pages, significantly higher-than-advertised commission rates, or showering them with free product samples will certainly get their attention, but it does not guarantee that you will get the heavy hitters to join your program, however.

As the CEO of TradeDoubler - a Swedish performance network with a vast European presence - William Cooper has his eye on global expansion. TradeDoubler, with its local offices in 15 countries across Europe, is known as the biggest affiliate marketing network in the U.K. Cooper was appointed president and CEO in March of 2007, riding a wave of first-quarter revenue for 2007, up 30 percent. Previously, Cooper, a six-year veteran of TradeDoubler, was COO of the company for a year. Before that, he oversaw the company's U.K. operations.

More than a year ago, Todd Crawford created quite a stir in the affiliate community when he departed Commission Junction, a company he helped found in 1998. He emerged at Digital River's oneNetworkDirect as its vice president of sales and business development, where he oversees affiliate recruitment and development, has profit and loss responsibility, and develops the technology road map and overall strategic direction for the company.

Many of today's online marketers have unrelated backgrounds and have learned their profession through on-the-job training and supplemental offerings.

The situation is similar to the first iteration of marketing on the Web in the 1990s. But unlike 10 years ago, there are more ways to learn and get information such as webinars and online courses; enrichment classes such as weekend training, conferences and boot camps; countless websites; and dozens of books and videos.
