Quality Settings let you adjust how traffic is counted. For example, you can exclude or discount traffic from specific countries, proxies, or JavaScript-disabled browsers.

Example: A trader sends a visitor who makes 10 clicks, all through a proxy. If ProxyDiscount is set to 20%, you count only 10 - 20% = 8 clicks for the trader.

For example, suppose you consider traffic from China (ch in this example) and Russia (ru) less likely to purchase and want to return less traffic to traders sending those visitors. The following example evaluates visitors by browser language, using HTTP_ACCEPT_LANGUAGE:

Set: - Env. variable name = HTTP_ACCEPT_LANGUAGE - Value = ru - Discount % = 30 - Skimming = 20

Visitors with Russian language settings are counted at 30% discount. If a trader sends 10 clicks from a Russian visitor, you count it as 10 - 30% = 7 clicks. Also, 20% skimming applies to that traffic. (If skimming = 0, this parameter is ignored.)

More complex example
Surfer made 10 clicks
language – ru
all clicks through proxy
10 – 50% - 20% = only 3 clicks will be counted.

Skimming is a custom skimming value for specific conditions. For example: - Value = ru - Discount % = 30 - Skimming = 40

Visitors whose browser language is ru receive a 30% click discount, and 40% skimming applies instead of the default.

Set Skimming to 101 to skip this parameter and use the value from &p= or Settings - CJSettings - Default Skimming.

Note that discounts are applied to clicks
For example   Value = ru  Discount % = 50
100 incoming hits match the ru condition. The incoming-hit count
remains 100.
Suppose they clicked 100 times: 50 on url and 50 on trade.
The Hourly Clicks Url, Hourly Clicks Trade and Hourly Clicks Total
fields will reflect real clicks, i.e. 50, 50 and 100
But Hourly Quality Url, Hourly Quality Trade and Hourly Quality
Total will reflect with discounts applied, i.e. 25, 25 and 50
Productivity is calculated from the Quality values. Discounts
therefore affect
productivity and, in turn, how much traffic is owed to the trader.
