Yes, Facebook and Instagram are connected and can be useful for affiliate marketing. By being on both platforms, you can share your content with a wider audience and potential customers. And, with the right strategies in place, you can drive traffic and conversions from both platforms.
That said, it's important to note that each platform has its own quirks and algorithms that you'll need to learn in order to be successful. For example, Instagram is more focused on visual content while Facebook is more text-based. So, when creating content for each platform, keep this in mind and create content that will perform well on each respective site.
