Posting cadence, account age & creator silence — what KOLens measures

Why agencies care about cadence (and most tools skip it)

Influencer databases optimised for sales decks show one number well: follower count. That's a vanity metric for paid campaigns. The real question for a brand team is: is this creator still active, and is their audience still hearing from them?

A 1.2M-follower account that hasn't posted in 6 weeks is functionally dead air — sponsorship money goes to a feed nobody's checking. KOLens surfaces the four numbers you need to answer the question in 5 seconds.

The four metrics

1. Account age

How long the TikTok user has existed, from user.createTime. Read directly from the platform's user record — accurate to the second. Surfaced as both an absolute date ("Joined Mar 2022") and a relative age ("3.2 years").

2. First video

The earliest video.created_at in the scraped batch. Sometimes equals the join date; often a year or two later (creators often sit on an account before posting). Use it to read the creator's actual content-creation history, not the signup date.

3. Last video — the silent-quit signal

Max video timestamp. KOLens applies an amber highlight when it's older than 30 days because that's the breakpoint where return-rate drops sharply (TikTok's algorithm down-ranks dormant accounts; creators rarely climb back from 30+ day silence).

4. Posting cadence

Two numbers, two purposes:

• Median days between posts — what's their habit? 1 day means daily, 7 days means weekly, 14+ means barely active.
• Videos per week (last 30 days) — current pace, for comparison-shopping between candidates.

We use median (not mean) for cadence so one multi-month hiatus doesn't skew a usually-weekly poster. The implementation: sort the scraped videos by created_at, compute consecutive deltas, take the median of the positive deltas in days.

How to read these in KOLens

1. Look up a handle on /kols (1 credit) — or click any creator from a keyword search.
2. The "Activity & cadence" card sits just under the profile header on /kols/[username].
3. Cards turn amber when a number warrants attention.

Filtering by activity in bulk

Once you've populated a KOL list, the activity columns are sortable. Drop everyone with last_video > 30 days; sort the rest by cadence and pick the top 20% — those are your highest-confidence picks for a 4-week campaign.
