Is Affiliate Marketing Saturated in 2021?

The affiliate has many ways they can earn an income by having an ad or link on their website, doing product reviews, using ppc and many more which prospective customers will hopefully click and proceed to make a purchase hence paying a commission to the affiliate.

When a potential customer clicks on the advertisement on the affiliates site, they are directed to the sellers website where they can buy that particular product, the affiliate then generates a sale which in turn earns a commission.

The more sales there are the more profit for the affiliate, so it is practical for an affiliate to use as many traffic sources when promoting a product as physically possible without using black hat or spam techniques.
