text: i hv no my own website,so i cannot join any affilaite program? if i can join the affiliate program and i decide to place their promote link/banner into some auction website or some advertisement website.can i do this?or only can place their promote link/banner in own website? it's going to depend on the web site you're working with.  some use the ip address of the sender to decide who gets credit for the click.  in this case, the auction site would get the credit.  others let you embed sender info in the link, in which case your plan may work.  i'd warn you, though, that most web sites where you can post things (including yahoo answers) have specific rules against what you're trying to do.  and most people who browse those sites get annoyed at people who are doing what you're talking about doing.   you won't win many friends this way.
