The position of your ad is determined by several factors that give your ad a score based on the quality of your ads and how much you are willing to pay per click. Even if other brands are competing for the same keyword as you are, it is possible to rank above them and pay less per click, but Google must see your ads as highly relevant in order for this to happen.
Cookie stuffing involves placing an affiliate tracking cookie on a website visitor's computer without their knowledge, which will then generate revenue for the person doing the cookie stuffing. This not only generates fraudulent affiliate sales but also has the potential to overwrite other affiliates' cookies, essentially stealing their legitimately earned commissions.
It’s free to join the SellHealth affiliate program, though you do have to apply and be accepted before you can start promoting their products. Once you’re accepted, you’ll have access to a number of tools, graphics, banners and more that you can use to promote SellHealth products. The sales are actually made at company-owned Websites, which look professional and handle all of the selling. Commissions vary, but the base rate is 30% of all sales and upsells, and SellHealth says you can earn up to $350 per sale.
