Lead generation is of course the core of your internet marketing business but the better companies to get involved in are the ones that provide you with guidance on how to generate leads on your own at no expense. The best idea of all, to avoid the trap of lead generation for internet businesses in my opinion, is to build your business on free leads first. If you have to go into buying leads than do it when your business is already generating income and put the initial profits back into the business to build it further. Always keep, your free stuff going, because needless to say your profit margin is higher on these leads since it only cost you your time, no hard cold cash to generate them.

If you do investigate a business opportunity that you are told requires buying leads you might want to just steer clear. Rather than get caught in the trap of lead generation for your internet based business.
Although some of these companies hide this fact until you are deep into setting up your business before they drop the bomb about lead generation.  I can almost promise you that there is no guarantee on the quality of these leads. I once got involved in a business opportunity that I bought leads for, because I was told, that is what I needed to do to succeed. The leads that I paid quite dearly for turned out to be people who often did not even recognize why I was calling and usually claimed that they never requested our services. They were typically always dead ends. I found this VERY frustrating.    

Based on my experience I would set up a list of questions to ask before I ever considered getting involved in another internet based business opportunity such as that. My first question would be; does this business provide help with generating quality leads for free on the internet? If you can master the free marketing opportunities first your chances for success are much greater. The worst thing you can do is throw your money at it hoping to generate the leads that you need. This will not get you anywhere and only cost you frustration for wasting money instead of creating a new income stream. When you do get to the point that you are ready to spend real money on advertising and lead generation, do it with a company that has a track record of success and avoid the trap of lead generation for internet based businesses.
