Affiliate Marketing Secrets

I am an affiliate marketer, and I have the products of the advertisers I sell. An idea would be selling online or even making videos with my show I have and making commercial like ads in between topics in videos. I know these are trying times and money is tight for many, but as a seller, should I feel bad? Should I feel bad for selling products as an affiliate, independent contractor or salesman? Asking for rational comments, not just a simple answer, greatly appreciated!

Hey guys so you all know about banners, a company makes them and gets affiliates to place them on their sites then when someone from that site clicks on that banner and goes to the companies site any subsequent sale is credited to the advertisers site and he is given a commission.
My question is, is there any way to do this with Facebook?
For example if I simply put a link on my fan page to someone site and then a Facebook fan of mine clicks it and makes a purchase, will it be able to get traced back to me?
Not sure if Im asking this right but you should get the idea. I have offers to advertise on my fan page and will get a commission of any subsequent sales.
Could this work?
How do companies usually track this kind of thing?
Thanks for the help guys 🙂

I decided to conduct my own examination.
I just listened to a 2 hour block of the Rush Limbaugh show on his San Francisco affiliate, Talk 910 AM.
In as liberal of a city as there is, in that time, Rush had 31 paid advertisers and 7 PSAs (Public Service Announcements). Only 1 paid ad was a campaign ad. All the other paid ads were from actual sponsors, including H&R Block, Toyota, Comcast, Lifelock, and numerous local sponsors. Nobody selling gold for some reason.
Yes, in 2 hours, there were probably an extra 3 or 4 PSAs. Hardly enough to put Rush out of business.
Yet if you listen to the Left, you’d think Rush is on life-support.

I am planning to build a website for some time now, i have a few ideas in mind, but i would like to know which subject areas are more lucrative than the others what competition is there for the advertisers and what product and services are sold in that particular niche. as i would like to make a small part time income from the site.
Please help with a list of subjects, Thanks in advance.

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.
