I have found great success with developing an affinity group (e.g. German Shepherd owners, muscle car fans, etc...) and then interspersing the content with offers that address their interest.
For example a group of pet lovers is encouraged to share their pictures and videos of their favorite pet. In the midst of those posts, we will then share a related offer such as pet food, pet supplies or other accessories.
The key is developing a sizable audience that shares the same interest. Get that group submitting the content and then introducing offers as part of the content flow.
Schedule a call with me if I can assist you further.
