> Unfortunately, the most profitable one is usually a fake download button to malware, or a site selling an e-book to lose 10 lbs in 10 days. This is completely false. The most relevant ad (statistically, based on real data) is going to be around something you actually want to buy, likely from a brand or product you saw recently, or are already a customer of. An e-book to lose 10 lbs in 10 days might be the best ad for someone who is in-market for short-term weight loss solutions, but is going to be a terrible ad for most people.
