Affiliate marketing and content syndication are two common forms of promotional partnerships. In affiliate marketing, one partner promotes another's products and earns a commission on sales. Content syndication involves sharing content across multiple platforms to reach a broader audience, often with reciprocal promotion agreements.

Cross-promotion and sponsorship are also key elements of promotional partnerships. Cross-promotion involves partners promoting each other's products or services within their own marketing channels. Sponsorships often involve one entity financially supporting another in exchange for promotional benefits, such as brand exposure at events.

Collaborative marketing and influencer partnerships are effective strategies within promotional partnerships. Collaborative marketing involves multiple brands working together on a shared campaign or project, while influencer partnerships leverage the reach and credibility of social media influencers to promote a brand's offerings.

Strategic alliances and joint ventures are more formalized forms of promotional partnerships. Strategic alliances involve long-term cooperation between organizations to achieve specific goals, while joint ventures create a new entity jointly owned by the partnering companies to pursue shared business objectives.

Co-branding and brand licensing are specific types of promotional partnerships focused on brand collaboration. Co-branding involves two brands creating a product together, leveraging each other's brand equity. Brand licensing allows one company to use another's brand name or intellectual property in exchange for a fee or royalty, expanding the brand's reach and market presence.
