The easiest thing to do is to sign up for an affiliate marketing network like Commission Junction. They provide a marketplace where your affiliate program will be advertised to other affiliate marketers. They also provide the tracking software for your affiliates so you don’t have to build your own tracking system. In some ways this is better because it takes care of the trust issues. Affiliates are always suspicious of whether or not they’re getting credited for the sales they generate. By having an intermediary take care of transaction tracking and payments, the fear of being cheated is alleviated. 
Data-driven advertising: Users generate a lot of data in every step they take on the path of customer journey and Brands can now use that data to activate their known audience with data-driven programmatic media buying. Without exposing customers' privacy, users' Data can be collected from digital channels (e.g.: when customer visits a website, reads an e-mail, or launches and interact with brand's mobile app), brands can also collect data from real world customer interactions, such as brick and mortar stores visits and from CRM and Sales engines datasets. Also known as People-based marketing or addressable media, Data-driven advertising is empowering brands to find their loyal customers in their audience and deliver in real time a much more personal communication, highly relevant to each customers' moment and actions.[37]
Digital marketing became more sophisticated in the 2000s and the 2010s, when[13][14] the proliferation of devices' capable of accessing digital media led to sudden growth.[15] Statistics produced in 2012 and 2013 showed that digital marketing was still growing.[16][17] With the development of social media in the 2000s, such as LinkedIn, Facebook, YouTube and Twitter, consumers became highly dependent on digital electronics in daily lives. Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.[18]
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.

Affiliate marketing doesn’t happen in a vacuum. It’s typically one of several marketing strategies a company is executing in concert. If you look at how each channel plays a role in customer sales, you get a fairly clear picture of which channels should be attributed to each sale. By resolving which channels create a higher cost of customer acquisition, you can optimize to help reduce those customer acquisition costs over time.

Websites and services based on Web 2.0 concepts—blogging and interactive online communities, for example—have impacted the affiliate marketing world as well. These platforms allow improved communication between merchants and affiliates. Web 2.0 platforms have also opened affiliate marketing channels to personal bloggers, writers, and independent website owners. Contextual ads allow publishers with lower levels of web traffic to place affiliate ads on websites.[citation needed]
