Think about emails or social media posts you've seen, where a group of people come together to share their gifts if you take some sort of action: buy a book, join a workshop or teleseminar. Not only is this incredibly valuable to you as a reader or guest to the event, it's incredibly valuable to the joint venture partners as well!
Let's say you have an important new product launch...for example, a series of online workshops. Whether you have a large or a small mailing list, you know you want to attract more people to the series than you can reach alone. This is prime real estate for joint partners!
In exchange for the opportunity to market their "bonus gifts" on your workshop website and to share the workshop announcements with their followers (and thus increase their marketing reach), you will be including their gifts in your own marketing for the series, and the gifts add greatly to the perceived value of your workshop series (simultaneously increasing your marketing reach). There are many ways to structure such a joint venture - read more about it online. But remember, you don't have to do it alone! Reach out to appropriate partners and share the rewards!
