Due to Twitter’s limitations, your tweet stats and analytics are only available since you started using Black Magic.
A limited amount of your past tweets’ stats will be available, usually from the past 30 days.
There is a way to import your past tweets to Black Magic. However, this only imports some data and not all of it.
For example, impression count, retweet count, and reply count may not be available from the tweet archive.
You can start to import your tweet by visiting this page:
