Most offers in the Smartlink are SOI and DOI. There is also a small number of PPS offers (1-2%).
You cannot leave only SOI offers in the smartlink. Although some offers can be optimized per certain GEOs upon your request based on your preliminary results.
Please note: We don't accept fraud traffic and can ban you for sending us fraud. Before start working with our smartlink/offers, look through traffic requirements for smartlinks and offers.
