A quick and inexpensive method of making money without the hassle of actually selling a product, affiliate marketing has an undeniable draw for those looking to increase their income online. But how does an affiliate get paid after linking the seller to the consumer? The answer is complicated. The consumer doesn’t always need to buy the product for the affiliate to get a kickback. Depending on the program, the affiliate’s contribution to the seller’s sales will be measured differently. The affiliate may get paid in various ways:
In 2006, the most active sectors for affiliate marketing were the adult gambling, retail industries and file-sharing services.[21]:149–150 The three sectors expected to experience the greatest growth are the mobile phone, finance, and travel sectors.[21] Soon after these sectors came the entertainment (particularly gaming) and Internet-related services (particularly broadband) sectors.

As search engines have become more prominent, some affiliate marketers have shifted from sending e-mail spam to creating automatically generated web pages that often contain product data feeds provided by merchants. The goal of such web pages is to manipulate the relevancy or prominence of resources indexed by a search engine, also known as spamdexing. Each page can be targeted to a different niche market through the use of specific keywords, with the result being a skewed form of search engine optimization.

The General Data Protection Regulation (GDPR), which took effect on May 25, 2018, is a set of regulations governing the use of personal data across the EU. This is forcing some affiliates to obtain user data through opt-in consent (updated privacy policies and cookie notices), even if they are not located in the European Union. This new regulation should also remind you to follow FTC guidelines and clearly disclose that you receive affiliate commissions from your recommendations.

File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content to file-hosting sites and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The websites that host the directory services sell advertising and do not host the files themselves.
I work as a freelancer and I also often use different affiliate programs, often associated with site designers or hosting providers. For me personally, this is a good extra income to the main orders. Recently, I also tried an affiliate program from the form designer and calculators https://ucalc.pro/en/affiliates Earnings, of course, less than on site designers and hosting, but constant. The bottom line is that I register a client in the service and plus to the whole I create a calculator on it for the client. Clients are happy and my money goes 🙂
What do you want to earn? Is this just a little bit of side income on your hobby blog or are you trying to replace your full time income? If you’re trying to go big then you’re going to want to focus on more high-quality products with big commissions.  Maybe you will be building your site or blog around the specific product you want to promote, like a product review or comparison site. Also be sure to consider the technical and tracking abilities of the affiliate platform being used. Not all affiliate tracking software is created equal and it's important that the platforms you choose to work with match the sophistication of the campaigns you plan on running.

Although it differs from spyware, adware often uses the same methods and technologies. Merchants initially were uninformed about adware, what impact it had, and how it could damage their brands. Affiliate marketers became aware of the issue much more quickly, especially because they noticed that adware often overwrites tracking cookies, thus resulting in a decline of commissions. Affiliates not employing adware felt that it was stealing commission from them. Adware often has no valuable purpose and rarely provides any useful content to the user, who is typically unaware that such software is installed on his/her computer.
