Hi,
Is it okay to post amazon aff link on youtube video description?
Read the Amazon Associates Terms of Service (TOS) agreement.
<rant mode on>I'm sorry, but questions like these drive me nuts. The EXACT information needed is easily available without relying on someone else to give you their idea on what the TOS says.
This isn't a dig specifically at maemis. I'm just using his post as an example of the type of things I see here all to often. For everyone... GO LOOK!
If there is an affiliate program you're interested in and have a specific question about it, go to the merchant's site and do some reading. Then you will KNOW you have the right info.
Using the example above, what if the OP had said (and he DIDN'T) he thought it you could probably earn commissions by direct linking from YouTube descriptions when it turns out you can't (I don't know if that is true -- just making a point).
So now you upload videos to YT with your direct links. You put in some work getting your videos to rank in the SERPS and then find out you don't get paid for traffic coming through your video description links.
Ultimately who's fault is it? The person that gave you the info or yours for not making the effort to first verify something that probably would haven taken 5 minutes in the first place?</rant mode off>
This is a really great thead!! So much information! In fact, I used the Search Thread option, searched by user and pulled up all the posts made by Virus1. Then, I copy/pasted each post into a text doc for quick and easy review/reference. Talk about a jam packed document!!
