Network marketing, also called multilevel marketing, is the process of recruiting a team of distributors to help you market a company’s products. Network marketing is a completely legitimate business opportunity, according to Entrepreneur magazine. Many large manufacturers operate on principles similar to network marketing, distributing their wares through multiple levels such as wholesalers and retailers before reaching the consumer. There are many types of network marketing companies, some of which are more common than others.

Nutritional Companies
Nutritional companies are the most common type of network marketing company, based on the "Top 25" list of network marketing companies at Nexera, an online reference and training site. Nutritional businesses are so popular because people generally like the products. These items are also highly consumable, and most distributors purchase these products monthly with an automatic shipment plan. People like nutritional products because they lose weight or experience increased energy when using them. Therefore, nutritional products also have wide appeal in the network marketing industry. Nutritional network marketing companies usually create many different brochures, tapes and videos to help their distributors recruit members into their businesses. Most nutritional network marketing companies also use conference call systems and postcard mailing systems to increase the success of their distributors.

Internet Service Companies
Anyone who reads business opportunity magazines knows that various Internet products also sell well through network marketing. People need a domain name or uniform resource locator (URLs), which is the location where customers find business websites on the Internet, for their businesses. Other popular Internet network marketing products include web hosting, web design software, auto responders and email marketing systems. All online companies need web hosts from which to run their sites. Yahoo! is one example of a web host. Businesses usually pay web hosts a monthly rental fee to keep their websites active. Auto responders are software tools that send out automatic emails to customers or potential customers. Email marketing systems are software packages that allow online marketers to send out thousands of emails simultaneously.

Information Products
There are also companies that sell information products via network marketing. In 2011, more informational product distributors are selling ebooks. The advantage of selling ebooks is that they cost the company little or nothing to create. The information products network marketing company does not have to pay to ship ebooks out to people. Ebooks are usually downloaded onto people’s computers automatically when payment is received. Still, some information products companies will distribute cassette tapes, CDs and video instructions to distributors participating in their business.

Cosmetics and Personal Care Companies
Some of the oldest network marketing companies, including Mary Kay and Avon, got started selling cosmetics, perfumes and personal care products. These items are purchased and consumed fairly regularly, which makes them ideal for network marketing. Many cosmetics and personal care companies use the party plan method for selling their wares. Distributors ask people to throw shows or parties where they show their wares to invited guests. Some distributors prefer to just make commissions from selling products. However, those who become managers usually recruit other distributors and earn commissions off their distributors’ sales as well.
