I am starting to think healthcare products could be a good niche as well. The U.S. dollar is garbage and the mortgage market is in a downswing. Healthcare however is recession proof.
People are getting sick or searching about their medical problems every day on the internet. I don't have formal health insurance myself so if I got sick or had a medical problem I would definitely do my research on the internet first before going to a doctor. Now I just need to find the best healthcare products to affiliate with.
