Yes. In fact, it is safer.
There are several reports on webmaster forums about Youtube removing videos because of Amazon links inside the video description. Even though this process is to fight affiliate spammers, many authority Youtubers have also had some bitter experiences.
We are confident that Prourls is the ultimate solution to this problem. Not one of our users has reported getting their video banned after switching to Prourls. We believe this is because of the quality of the affiliates who prefer Prourls. While we are on the safer side, we cautiously advise our users to avoid spamming and continue to provide great value.
