what is the best affiliate product that REALLY sells??

Well, FOR SURE anyone that has been successful now in affiliate marketing didn't happen overnight. I know for most of them took about a year or more to reach their desired level of success specially in terms of money. The first thing to learn about being successful in affiliate marketing is having the correct mindset that affiliate marketing success doesn't happen overnight. Second build a long trusting followers focusing on giving and helping them what they need without asking in return or without selling something(well.. you could do a bit of selling, but make it subtle and not overdo it). Building trust from your followers/audience/readers really takes time so you gotta be patient and never be in a hurry to make a sell. One common good way to do this is creating relevant good content/information in your blog (and do backlinking). These are old school teachings about internet marketing but it's the basic and it's still proven to work rock-solid :-)

Affiliate marketing really good if we learn the right process. I am new to that program and what I did was to make a blog and post products that I want to promote then share it to facebook and promote it in anyways...
