Affiliate Marketing Secrets

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.
