Affiliate marketing tracks a consumer from a referring source to a completed sale. When we think of affiliate marketing in this simple manner, it opens up an entire realm of possibilities.

However, for the most part, affiliate recruiting efforts are primarily focused on entities that drive online traffic, such as bloggers, search marketers, shopping comparison sites, and coupon and deal sites. If we broaden our mindset and consider that affiliate marketing is simply a tool that enables us to pay commissions for online sales, regardless of where the consumer came from, this expands our affiliate possibilities to include offline entities.
