Juicyads is a live bidding platform which means that what you earn from our advertisers is not static. Some days you may earn more or less with the exact same amount of traffic from previous days. There are a few reasons why this may happen:
1) Advertiser bids may change Much like the stock market, what you may earn is based off demand. Meaning that advertisers may pay one price for traffic to a specific country one day, and less the next. There is no way to really control this, but generally ensuring you are driving traffic from (English speaking) Tier 1 countries like US, UK, CA, AU, NZ, IE, etc. will increase the likelihood of you earning the most.
2) Advertisers may be blocking your website This does not mean that you have a bad website, or that your traffic is not good. Not all offers work well on all websites. Its a numbers game, and if an advertiser is spending a lot of money of traffic to your site, but their offers are not converting, they will block you. Don't take it personally. If your sites traffic is real, for every advertiser that blocks you, there are dozens more that are paying to have their ads displayed on your site.
3) Change in Traffic Quality If you are getting alot of traffic from Tier 1 countries one day, and the next day from Tier 3, this could explain swings in earnings even though your traffic stats appear the same.
As mentioned above, traffic from Tier 1 countries pays the most, followed by Tier 2 (European Countries and Japan) and Tier 3 (The rest of the world). In short, 1000 clicks from Tier 1 countries will pay more than 1000 clicks from Tier 2 or 3 countries.
