A listing was posted that reached a monthly revenue of $5k in just 10 months.
Very high monetization rate per traffic: $688 per 1k unique visitors. 4 affiliate programs with a good distribution of revenue across them to eliminate the risk of any single program cutting commission rates.
Mostly US traffic, and a 301 redirect from 6 articles was used, likely to consolidate the link profile and push the site even harder.
