Can I direct link from Youtube to a Clickbank product? If not, can I do a re-direct (like ezinearticles.com) from a top level domain? Or are these methods against the TOS? Thanks
If you're worried, why not just use a url shortener like tinyurl.com, bit.ly,etc. As long as you're video is not copyright and you are not promoting anything illegal or against their terms, then you will be fine.
I always recommend everyone use their own domain/hosting even for direct linking, this will allow you to "own" the traffic and make changes if required
It better doesn't use your Hoplink. Cloaking your URL by using your own domain or short url service. I am always using that 2 method. Until now never have a problem.
It is better to linking to one of your product review page of your site. CPA offers works well by direct linking as compare to CB products. Use youtube for only driving traffic to your website or landing page.
