I'm still confusing for reading information on info graphic, especially about the right time to post ads on face book,.. the problems is ; " is that the same case for report published by survey company to every country to be implemented ? or every country has own characteristic for best timing to post ? for Example : some said that after 4 Pm was not good to post in Facebook ? (I red in the survey) I'm usually posting ads on FB group,.. Thanks for the advice
