Why is it beneficial for a brand to offer unique promo codes to partners?

Unique promo codes are beneficial because they provide an alternative tracking method for partners who may struggle with traditional tracking links. Influencers and podcasters, for instance, often promote products verbally or in environments where clicking a link isn't seamless. A unique code allows their audience to make a purchase directly on the brand's site while still attributing the sale to the specific partner. This ensures accurate commission for the partner and provides valuable data for the brand on the effectiveness of different promotional channels. The other options are incorrect because promo codes do not inherently change payout timelines, sales can still be tracked via traditional links, and banking details are always necessary for partner payouts, regardless of the tracking method.
