When you make a part of different marketing systems, you often begin with Traffic Exchanges. Because you look for free traffic, first of all. I do not want to write a long speech that you have to buy traffic - yes, you have to, but if you begin with TEs, means you have a very serious reason for it. 

So, we begin with TEs. And we understand that they can't expose our link to enough visitors, because "business online is numbers". You probably can click for one-two hours a day, but it gives you on average about 100 views a day. And it's not enough. 

Is there something what can help us on our way? Yes. These are Free Classifieds sites. 

Why are they so good for us? There are different reasons:

1. we have free backlinks that are good indexed.
2. we have free traffic because the classifieds sites are normally visited by many persons.
3. if we are smart enough, we can find very interesting offers and tools, both free and paid.

So, for example, the Free classifieds site "Quick Find Global" that has at least 500 visitors a day, has great variety of industry new tools. There are really precious reports, specially for a newbie, but interesting for expert internet marketers, too. There is a free URL submitter and much more. This way, the site is an important resource, not only free backlink and visitors "provider".
