No matter how good your marketing skills are, you’ll make less money on a bad product than you will on a valuable one. Take the time to study the demand for a product before promoting it. Make sure to research the seller with care before teaming up. Your time is worth a lot, and you want to be sure you’re spending it on a product that is profitable and a seller you can believe in.
Know the legal requirements. Most visitors will probably understand that advertisements lead to your personal compensation, but if you write a review or use an in-text link as a recommendation, you must explicitly state that each purchase using that link can generate revenue for you. This isn't just good business: it's also required by law. If you don't disclose affiliate or revenue-generating links, you could face legal and financial penalties.
This relationship can take multiple forms. You may partner with a brand launching a specific product and receive a percentage of the revenue generated by your referrals. Or, if you work with websites like Amazon, you receive a percentage of whatever purchase a follower makes through your referral links, even if they don't buy the product you were specifically recommending.
