So I recently saw an episode of the "No Labels Necessary" podcast where they spoke about the power/ effectiveness of reposting your content with slightly different titles, headlines, lengths, etc.
I've been reposting content regularly since 2023 began and I've definitely seen positive results. Attached are two screen shots, one before when I posted the clip two months ago and one from today. This is one of many examples on my personal social media accounts of reposts that greatly outperformed their original counterparts.
I hope it encourages you to give your older content some new life!
