I want to advertise my site for under $50 and get massive traffic to my work at home program. How do I do this?

Good luck with that. $50 won't get you any decent advertising anywhere for enough time to get significant traffic.

If you are not willing or able to invest in your business, you could make sure your site & product are original and among the very best of its kind, and spend a lot of time working social media. Now that doesn't mean posting nothing but links to your site all the time. Get involved - actually converse with people who could be interested. Let people get to know what you can do for them without being pushy. If you have a good product, word of mouth will work for you.

Otherwise, find the money to pay for ads, or pay a good SEO consultant to guide you. If you are serious about your business, be prepared to pay a serious, realistic price to market it. Cheap SEO (which is usually spam or nothing useful at all), and "rookie mistakes" based on bad advice will quickly destroy your business.
