You don't always have to create new content. Especially when you have a lot of content that could be re-used (after you make it better).
I started going deeper into the stats of my TikTok content and built a system to re-engineer it for more views and performance. It takes a bit of organization to do it right but it's well worth it.
I use Airtable to store/link all my content
I pull in social analytics to compare the performance
I use the organization to re-engineer the clip quickly
Then I repost it and keep track of 2nd, 3rd revisions, etc
Let me know if you have any questions glad to help.
