Affiliate Marketing Secrets

My online income strategy begun with the creation of two personal blogs. One of the will be focused to my professional degree in the field of studies: industrial engineering and technical consulting. The other blog is now oriented mostly to provide tourism and worldwide travel, focused on luxury and even budget travelers. My last blog called www.Reportame.com is having about 30 000 articles in several niche markets but there are more articles about tourism. I have both affiliate and basic email marketing running right now. In this moment I am looking for joint venture partners in Costa Rica, but are very hard to find. Most people, even professionals are alergic to create online businesses. Knowing the risks of being an pioneer, I am hoping to get ideas from the most visited websites in my country, but my blogs are more oriented to provide solutions to any English speaking people. What do you recommend to get ahead of any competition and have a better return over my investment?
