The reasons may be various. The main one is the exchange rate - advertisers can settle with MyLead in a different currency than the one in which we pay you - currency fluctuations result in slight changes in the amounts of the leads you receive. The situation is different for smartlinks, which combine tens or hundreds of different campaigns in one affiliate program. In this case, the fluctuations in leads amounts depend on a high rotation of advertisers, which results in changing the rates relatively often.We make every effort to ensure that the rates in the affiliate program descriptions are always true. However, due to the reasons described above, the amounts you receive may differ from those presented in the descriptions.
