There are two tips that you must always consider before joining a network marketing company. The longevity of the company and its overall profitability are definitely things to consider, but you must also believe in the company that you are going to join. 

The first thing you need to do is evaluate the company and see if you would mind representing it to other people. 

The second thing you need to consider are the products that you will be purchasing. 

If you can see yourself working with the company, and you enjoy the products that they offer, this is the company that you should join and try to build a business with.
