Affiliate Marketing Secrets

Thanks in advance!!!!!

I am trying to make my own website for the affiliate program SFI, so I need some programming tips.
I’m already a decent coder with HTML so I can do basic stuff there, but with javascript I’m a little rusty. By javascript I DO NOT MEAN JScript or Java. Do not say w3schools, or echoecho. I have used both, and have found w3schools to be incredibly confusing and echoecho when it comes quiz time, the ads disrupt it.
AGAIN
DO NOT SAY W3SCHOOLS OR ECHO (unless you know how to turn off ads on Echo)
I also need to learn JavaScript for it. Just little things, not much. Again, NO W3SCHOOLS OR ECHO (Unless you can turn off the ads in echo)

I’d like to try my hand at affiliate marketing, but I don’t want the hassle of keeping up a website. Can I still participate in affiliate marketing? If so, how?

I want to sell some design templates on web, but why do the websites who offer this affiliate earnings do ask for our own website and its details?

My very good youtube helpful videos have been uploaded to many websites. I am an affiliate for a product and offer some review and some education but I hope to get the affiliate sale.
I see that these other websites insert a clickable link at the end of my video essay description.I see that these other websites put clickable links into my essay that connect to their advertisers.
My question: Is this beneficial for me to have allow my youtube videos out there. (Since they may have a higher ranking site than my own website)
Thank you for your help.
