1- Focus on High Commission Products:
This may seem obvious but is makes a big difference! when you promote products, focus on promoting good products from the highest tier, T50 products provides you with 10X profit compared to the regular T5 products. You also have the T20 which also provides you with a good profit... eventually focusing your efforts on the hier tiers is the first tip to make the REAL money.
2- Use Links in a Smart Way:
If your link is "https://www.gosupps.com?k=abc" then you can create any link that will forward the user to a specific product page by adding your own "?k=" parameter at then end of that URL like: https://www.gosupps.com/optimum-nutrition-gold-standard-100-whey.html?k=abc".
By that you will be able to make specific promotions to specific products on your own channels and let the user clicks on these URLs to directly visit these specific products directly wthout the need to visit the Home Page then search for that product to reach it's related page.
