What a good system should do, first of all, is provide leads, which are the lifeblood of any MLM business. There are many good MLM or network marketing systems on the internet; you just need to find the right one for you, with the promotion systems that suit you best. All online network marketing systems have some common features:

“    A strong leader and spokesperson

“    Unique product(s): most of these systems have their own products, sometimes the self-contained marketing system.

“    Lists: all of them collect and save opt-in permission contact lists of customers or potential customers.

“    Joint-venture partners – these are usually respected online marketers with large opt-in lists that will help create momentum and sales for just about any product.

“    Auto-responders: one of the most effective marketing tools, a series of automated follow-up e-mails that dramatically increase sales.

“    A toolkit of marketing resources: marketing resources such as lead capture pages, SEO tools, links, graphics, banners, landing pages, brandable reports, articles or e-books.

“    Viral marketing, which may use simple brandable reports, or articles, software, e-books that then get passed around all over the web.

“    Media to spread the information: the company’s blog, members’ blogs, RSS feeds.

“    Automation: the whole system is automated to the degree that it’s possible; otherwise they couldn’t support such large networks.

“    The global marketing opportunity offered by the internet: the opportunity to market in all countries of the world

There are the “out-of-nowhere” systems that boast with complete automation, telling you that you don’t have to do anything but sit back and enjoy the money. This should raise a red flag for you, as, many times, these systems won’t provide value; it’s possible that they won’t provide quality leads, or it’s possible that they control your list.
Then, there are the systems where usually the provider is a thriving internet marketer; they have a product, they give you the instruction and the technology you need, and, with a good mentor to guide you, you can become a strong network marketer yourself. A good part of the branding will belong to them, though, so they will have some control over your marketing. For beginners, this will be a good thing, though.

There is another type of system, one that is a definite advantage for the experienced network marketer, as it allows him to promote himself only, giving him complete control over his branding, his list, and his marketing. At this point, people will flock around him for himself, not a product, for his training and leadership that should help them achieve success no matter the MLM business or system they opt for.
Unless you are already an internet marketing guru, the best advice I have for you is to look for an experienced network marketer to guide you. Some say your success is not a matter of what you join, but WHO you join. Think about it, it only makes sense that it’s your mentor who influences your success rather than the system you use.
