exactly what i was thinking because theres will never be saturation in those niches! but i have a question which niche has more buyer potential?There's no such thing as a saturated method on facebook. There's billions of people active on facebook. You can make money a million times over in the same niche. You just need to be creative. Stick to most popular niches like Health, Wealth and Dating. You cant go wrong with those.
