I find it interesting that you talked about nutrition supplements for athletes. I am very close to launching such a product for enhancing aerobic exercise performance in women (ie. improved times in a 3 mile run).. The product contains no stimulants or exotic herbs. In fact three of the five ingredients are well known minerals, but in forms not found in most multi-vitamin-mineral supplements. The research behind the product comes from me.

Thanks for a this timely article. If I understand it correctly, are you saying that we would better be off looking at market data in our niche and make an article of that for influencers to share rather than actionable tips that the target clients would be interested in?

Firstly, a disclaimer – don’t spam Reddit and other similar sites hoping to “hit the jackpot” of referral traffic, because it’s not going to happen.
