In short
- Ask for the 90-day follower chart, plus follows and unfollows where shown, with dates. Read the shape first, then ask the creator to tie each jump to a post.
- Six shapes cover most cases: steady slope, spike that settles, step, stair-steps, sawtooth churn and cliff. Each has a different honest cause and a different question.
- Test growth against views. If followers rise while median views stay flat, the new followers are not watching, and you should price on views.
- Giveaways and paid follower campaigns explain jumps honestly but change who follows. Ask about both, and compare engagement before and after the jump.
To check an influencer's growth history, get the 90-day follower chart and, where the app shows it, the follows and unfollows view, with dates visible. Classify the shape, ask the creator to tie every jump to a specific post or event, then test whether views rose with followers. Real growth tends to follow content. Bought and contest growth tends to arrive in steps, with no matching rise in views.
Step 2 of our guide to how to spot fake followers gives the short version, and how to read influencer audience insights shows where the chart sits among the other screens. This post goes one level deeper on that one chart. It is check A2 in the scored sheet in our influencer vetting checklist, and it sits under our complete guide to influencer marketing in India. Menu names and chart ranges change with app updates, and labels change, so ask the creator what the screen they send is called.
What to ask for
| Item | Why you want it |
|---|---|
| Follower chart for the last 90 days, with dates | The shape of growth |
| Follows and unfollows view, where the app shows it | Gross gains and losses, which expose churn behind a flat total |
| A link to the post behind each jump | Lets you check the cause yourself |
| Dates of any giveaway, contest or paid push to gain followers | Explains the honest jumps |
| Median Reel views for the first and last 30 days of the window | Tests followers against attention |
| An older media kit or rate card that states followers and a date | Gives a before point when the app shows nothing older |
| On YouTube, subscribers gained and lost, by video | Shows which uploads brought viewers and which brought churn |
Public subscriber and follower counts are rounded on some platforms, so ask for exact figures in the chart. If the creator cannot produce a chart at all, that is itself a signal; the stop rules in the vetting checklist apply after two requests.
Six shapes and what each one means
| Shape | What the chart looks like | Honest causes | Questions to ask |
|---|---|---|---|
| Steady slope | A gentle climb with small bumps | Regular posting and a loyal audience | None; this is the boring, good one |
| Spike that settles | A sharp rise over days, then the old slope resumes at a higher level | A viral Reel, a feature, a big creator's shout-out | Which post? Do its views fit the jump? |
| Step | One or two days of large gains, then flat | A giveaway, a paid push, a collab post | Which date, and what happened that week? |
| Stair-steps | Flat, jump, flat, jump, at regular gaps | Contests every few weeks | Is this a routine? Are entrants real buyers? |
| Sawtooth | Daily gains and losses that net near zero, with large gross numbers | Little honest cause; it is a mass follow and unfollow routine | How does the creator grow the account? |
| Cliff | A sudden drop | A platform clean-up, the creator removing bots, a restored account | What happened, and did views change afterwards? |
A flat plateau for months is a seventh pattern and not a fault. It means growth has stalled, and the check then shifts to views: a stalled account with healthy views is still a sound booking.
Test growth against content
Three tests turn the shape into a decision.
The jump and post test. Every jump should trace to a post whose views are far above the creator's median. For each explained spike, work out followers gained per 1,000 views of that post. We found no published benchmark for that figure, so compare the creator's own spikes with each other. If two viral Reels produced similar yields and a third jump produced a very different one with no post behind it, the third needs an answer.
The followers and views test. Compare the change in followers across the 90 days with the change in median Reel views between the first and last 30 days. Followers up by a quarter while views barely move means the new followers are not watching. That is the pattern bought and contest followers leave, and it is the number to price on.
The before and after engagement test. Use the engagement rate calculator on the five posts before a step and the five after. A giveaway or paid push that dilutes engagement shows up here. Our guide to Instagram engagement rate benchmarks shows how to read the result by tier.
YouTube: subscribers and viewers are different
On YouTube, the subscriber chart is only half the story, because a large share of views can come from people who never subscribe. Ask for subscribers gained and lost by video, and set it beside views for the same uploads. A channel that gains subscribers mostly from one or two videos, with the rest flat, depends on those uploads, so price the integration on the views the typical upload earns. A sharp subscriber rise with no matching rise in views over the following weeks follows the same logic as an Instagram step: the new subscribers are not watching. Our guide to YouTube influencer marketing for brands covers formats, and how to read influencer audience insights covers the retention and traffic screens that belong beside this chart.
Honest growth that still changes the audience
Some causes are legitimate and still alter who sees your product.
| Cause | What changes | What to do |
|---|---|---|
| Giveaway or contest | Prize-seekers join; many leave or stay silent | Ask for the entry rules and check engagement after |
| Paid promotion to gain followers | The audience mix follows the creator's targeting | Ask for the targeting, then run the location check |
| Collaboration posts with other creators | A borrowed audience that may overlap with others on your list | See influencer audience overlap analysis |
| A viral post outside the creator's usual topic | Followers who came for something else | Compare comments before and after, as in comment quality analysis |
| A new language or format | A different audience on top of the old one | Ask whether the content you are buying matches the new audience |
None of these is a reason to drop a creator. Each is a reason to price on current views and to check the audience screens, not the follower total.
Red flags
- A jump with no post, event or promotion behind it, after you have asked.
- Stair-steps at fixed intervals that match no content calendar.
- Large gross gains and losses with a flat net.
- A follower total that rose sharply while median views stayed flat or fell.
- A cliff that the creator cannot explain.
- A chart that has been cropped, or one without dates.
- A rate card or media kit whose follower count today is far above the old one, with no growth story.
A worked example
What to say to the creator
Ask without accusing: "Your chart shows a large rise in the week of the tenth and a drop two weeks later. Could you tell us what happened, and share the post or promotion behind it? We ask every creator to explain jumps in the 90-day chart." Creators with a clear answer usually reply in minutes, often with a link. A reply that changes the story across messages, or a refusal after two asks, belongs in the vetting checklist's stop rules, and a conversation with a previous brand, covered in influencer reference checks, can settle what the chart cannot.
How the Gully Score uses growth
Audience authenticity carries 30 points of the Gully Score, and growth over 90 days is named in how we score it: sudden follower spikes are one of the red flags the score looks for. In the sheet, A2 (follower growth is gradual, or spikes are explained) carries 6 of the 30 authenticity points. That split is our suggested split for a manual sheet, and the criterion total is the Gully Score's own. The same chart informs A3, because reach per post should climb when followers do.
Growth is also the check most worth repeating. Re-run it before every rebooking and after any sudden follower jump, as the vetting checklist advises. The Gully Score checks follower growth over 90 days for every creator we propose, across our Instagram influencer marketing and YouTube influencer marketing work. Send us a brief and the plan, with scores and names, returns within 48 hours of the brief call.

Frequently asked questions
How do I check an influencer's follower growth history?
Ask for a dated screenshot of the 90-day follower chart and, where the app shows it, the follows and unfollows view. Classify the shape, ask the creator to link each jump to a post or event, and compare median views at the start and end of the window. Our vetting checklist shows where the result scores.
Can I see growth history without the creator's insights?
Only roughly. Older media kits and rate cards with a stated follower count and date give you points to compare with today. Archived copies of public profile pages exist for some accounts, though coverage is patchy, and analytics tools estimate growth from public data. Treat these as a screen and confirm with the creator's own chart.
What does a sudden follower spike mean?
It can mean a viral Reel, a feature, a shout-out from a bigger creator, a giveaway, paid promotion or bought followers. The spike alone does not say which. Ask for the post or event behind it, check that the post's views fit, and look at engagement after the jump.
Is a giveaway spike a red flag?
Not by itself, because giveaways are a normal growth tactic. They change the audience, though: many entrants follow for a prize, not for the content. Ask about the entry rules, compare engagement before and after, and price on median views. Our fake followers guide lists giveaway followers as a distinct type.
Does a drop in followers mean the creator had fake followers?
It can. A platform clean-up or the creator removing bots would show as a drop, and that is not a bad sign in itself. A drop can also follow a bought batch or a mass follow and unfollow routine. Ask what happened and compare views before and after.
How far back should the growth check go?
Use 90 days for the decision, because it is long enough to show a pattern and short enough to explain. If the creator can show a longer period, a year gives context for seasonality. App views and labels change, so ask what range the creator can export.
How should growth history affect the fee?
Price on current median views, not on the follower total. After a spike, wait for views to catch up before paying for the new total, and re-check the chart before every rebooking. How to benchmark influencer quotes shows the arithmetic.
