How many of your Twitter followers are still active?
I’d had this question over and over and over, so I finally built a tool to answer it for me. That’s ActiveRank.
And it answers it by looking a very easily accessible data point within Twitter’s API framework. That being a user’s last tweet date. What this tool does is scans up to 10,000 of your followers and breaks them up by how recently they’ve been active enough to tweet.
It’s not a perfect measure, but given API rate limits it gets really close to the actual number really quickly.
Examples
For example, on my personal account that exploded with followers 6-7 years ago but has seen average growth since then, you’d expect to see it skew toward inactive.
And it does.
Running it for a brand new account like PeakFeed, you’d expect to see it skew toward very active.
But for an account that’s been consistently updated and has grown steadily for 5+ years, you’d expect something right in the middle.
And you do.
