Sure you can start affiliate marketing as a beginner this 2022. You can go through my threads after reading this;
You can start by getting top individuals in this line, notable authors/bestsellers in your niche to sell their products, based on your agreements they pay you commission on books sold. You can decide to get your commission sent into your account monthly or weekly. I would prefer weekly just to save anybody the stress of paying me huge amount of money monthly , at least on a weekly basis no body will feel reluctant to pay me my commission on a book i sold.
But how do you do this, you need to market any item you are promoting or trying to sell. You can make sponsored ads on social media , offer to anchor a webinar free, sell on sellar (don't mind my spelling) , kdb amazon and the likes. You can create landing pages where people can reach you too and you get their so they don't just buy your products and leave. Through the landing page , you can retarget them and also inform them about your new products through email.I hope it helped you to start well.
