What is a 'Validation Rate'?

How to calculate the validation rate

[spchlss]

Hi All,

I'm new to affiliate marketing and I'm hearing about something called a 'Validation Rate' of programs in affiliate networks, and I'm just wondering how it is calculated.

I understand that when a sale is lodged it is then validated or deleted, or something like that?! Is that where it comes from?

Thanks.

Welcome to WebmasterWorld. Validation rate can be used in the lead gen area where leads are validated as not being fraudulent.

thank you!
Is it usually calculated on a monthly average?
