Cookie stuffing or cookie dropping is an illegal affiliate marketing technique. It’s when you place a cookie on someone else’s computer without their knowledge. Some people utilize it on their review sites so that they can still earn a commission even if the visitor does not click via their link.
In other words, instead of leading people to the merchant’s website, you’re making money by discreetly loading the website (and dropping the affiliate cookie) in the background without the visitor’s knowledge. Most people regard it as blackhat marketing. If you are caught employing this method, you may be banned from an affiliate or CPA network.

What is Affiliate Marketing?
A simple explanation of affiliate marketing for those who are unfamiliar with it. Affiliate marketing is a type of performance-based marketing in which a business compensates one or more affiliates for each visitor or customer brought in through the affiliate’s own marketing efforts.
The affiliate tracking software sets a cookie on your computer every time you click on an affiliate link. This cookie saves vital information about your clicks, visited pages, and the referring affiliate. When you complete a transaction, the affiliate tracking system will locate this cookie on your computer and provide a commission to the referring affiliate based on the information contained within.
As a result, many affiliates make money by using cookie stuffing scripts to actually get transactions counted in their favor, when in reality, they were not the legitimate partner to deliver the sale.
What Is the Purpose of Cookie Stuffing?

So, what is cookie stuffing, and can you do it?
Cookie stuffing with an image is the most basic method of cookie stuffing. Instead of a genuine image, cookie stuffer uses an HTML image tag (<img>) to create a 1px * 1px image that goes to your affiliate link. When the page is loaded, the visitor’s browser will try to load the picture but instead will load the page linked in the tag, and your cookie will be deleted.
Example:
The main disadvantage of this method is that anyone with access to your source code can see that the image is simply a disguised affiliate link.
The Iframe Method for Cookie Stuffing
Iframe cookie stuffing is an alternative to image cookie stuffing. To do this, create a 1-pixel iFrame on your page and then have that iframe load your affiliate link. Again, the possibility of being caught here is reasonable, as someone only needs to open your source code to see you.
Plugins for WordPress
There are several cookie stuffing WordPress plugins available and affiliate cookie stuffing software. Plugins are the most convenient approach to packing cookies and sometimes make detection tough. On the other hand, some cookie stuffing plugins are extremely dangerous because they are programmed to drop the developers’ cookies on your users (without your knowledge) or even secretly reroute visitors to a different page.
