# Click tracking Macro for DSP's
Для отслеживания клика в баннерах SSP UMG ожидает, что DSP добавит макрос ${CLICK\_URL} или ${CLICK\_URL\_ENC} в adm в своем bid responce.
SSP раскрывает его в свой URL трекинга клика таким образом, чтобы в конец можно было конкатенацией добавить URL редиректа.
Если в bid response в adm SSP видит макрос ${CLICK\_URL} на прим. ${CLICK\_URL}', он будет раскрыт в трекинг URL, прим.
В конец мы подставяем URL для редиректа (click url), который окажется в dst параметре click трекера SSP. URL кодированный или не кодированный.
В итоге при клике будет вызван, URL следующиего вида
* Если макрос ${CLICK\_URL} - то в обычном виде =
* Если макрос ${CLICK\_URL\_ENC} - то в url-encode виде = https%3A%2F%2Fssp.com%2Fclick%3Fdst%3Dhttp%3A%2F%2Fexample.com%2F
