Design unique posts for each platform
Cross promotion is different from cross posting. Cross promotion highlights a single piece of content across multiple platforms, but does so in a way that's unique to each individual channel. Cross posting simply takes the same promotional content and uses it on all channels.
For example, if you wrote a blog post about the top 10 must visit restaurants in Waikiki Beach, you could post a video on TikTok of the dishes you ate at the 10th restaurant on the list. This type of content might also work great as an Instagram Reel! While it might be tempting to simply export the TikTok and post it to Instagram, you risk alienating platform-specific followers. Fans who are used to engaging with you on Instagram might be turned off by the burned in TikTok logo, or think it was posted by mistake. Or, they may think you’re trying to direct them to your TikTok instead of your blog.
