Hello everyone,I want to clarify some information about Pay Per Download concept. I am new to this PPD concept. I have checked some PPD sites like cleanfiles, sharecash, depositefiles etc on google but when I tried to download from those sites, i needed to fill the survey and i did that but still couldn't able to download the file..those sites really pay for downloading any file? May be some get the file and some couldn't get the file after filling the survey form.I want to know the reason. If people wants to download the file which is uploaded by me on some PPD site and if he/she can't download it then I will not be paid even though he/she has filled the survey form. One more question, Can anyone tell me which kind of file should be uploaded to those site that attracts users positively?? I have already know the methods of getting users to that site like YT, metacafe or P2P programs..is there any other method available? Sorry if I ask anything wrong in this section...any suggestion would be great for me..
