A traffic source is any media (paid or unpaid) where you place content that results in people clicking on your ad.

You start with unpaid media (YouTube, Facebook, Instagram, etc) and once you get results move to add on paid media.

The key is the value of your content.

In affiliate marketing, a traffic source is the platform or channel where your potential customers come from. It’s how visitors find your affiliate link or landing page. Common traffic sources include search engines (Google), social media (Instagram, YouTube), paid ads, email marketing, or content platforms like blogs. Choosing the right traffic source is essential because it directly impacts how many people see your offer whether they convert into commissions.
