Track follower growth with dated counts from the same source. A record that begins today can show future change. It cannot recover every earlier gain, loss or acquisition source.
Record a reliable baseline
Save the account ID or profile URL, capture date, time zone, follower count and source. Keep observations at a consistent interval. If a day is missing, leave it missing rather than inventing a count.
Tweet Archivist records follower-count snapshots for profile archives. Its chart uses up to the latest 30 snapshot records. The interval depends on actual collection and updates. A snapshot count is not a list of follower identities or demographic attributes.
Calculate net and percentage growth
Net change = ending count − starting count. Growth rate = net change ÷ starting count ×100.
Hypothetical example:5,000 followers increasing to 5,250 is a net gain of 250 and a 5% growth rate. This does not mean only 250 people followed: gains and losses may both have occurred. If the starting count is zero, percentage growth is undefined; report the absolute gain.
Interpret patterns without invented attribution
Add notes for launches, events, unusually useful posts and interruptions. A count increase after a post is a correlation, not proof that the post caused every new follow. Compare several similar periods before changing your plan.
Compare both percentages and absolute counts. Gaining 50 followers from 1,000 is 5%; gaining 50 from 10,000 is 0.5%. Neither account is automatically performing better without knowing goals, effort and audience relevance.
Use a short review log
| Observation | Question | Next action |
|---|---|---|
| A one-day decline | Was collection complete? Did account availability change? | Confirm the next observation before reacting. |
| Sustained increase | Are useful replies or enquiries increasing too? | Review content and outcomes together. |
| Count unchanged | Could new follows offset losses? | Do not infer zero audience turnover. |
There is no universal healthy monthly growth target here. Use a simple tracker to start logging. Named-unfollower analysis requires separate identity data, explained in the unfollower guide.
