Search Engines - Reciprocal Links Exchange
1) TARGETED LINKS If you exchange links with websites that are related to the topics covered in yours (highly recommended) then visitors that click on your links will be targeted. They will already be interested in the site that you exchanged links with and so will be looking for more information on the topic.
Notice I said 'simple concept' not 'simple process'. It is a lot of work to find sites that have a similar audience as yours, then search their site to see if they even offer free links to other sites, and then find contact information to ask them to link to you.
If you are committed and you devote enough time to develop your "business" to make it successful, MLM CAN and probably WILL make you a millionaire. MLM is probably the easiest and fastest way to make a lot of money when you are successful (unless you win the lottery or you are a professional athlete of course!).
