Posting cadence describes observed publishing activity. It does not identify the best schedule for your audience or prove that posting more often causes higher reach. Start with a stated question, a relevant account set and clearly dated evidence.
Two measurements that answer different questions
If you have verified every eligible post inside a fixed calendar period, dividing the count by the period’s length in weeks describes activity during that complete period. State the start and end boundaries, timezone and included formats. Do not claim completeness from a limited returned sample.
The V5 posting-frequency estimate instead uses the observed interval among eligible, non-pinned posts with valid dates: 7 × (n − 1) ÷ elapsed days, where n is the eligible post count and elapsed days is the positive span between the oldest and newest eligible timestamps. With fewer than 2 eligible posts or a nonpositive span, that estimate is unavailable. It is not the same as dividing a limited sample by an assumed month.
An illustrative calculation
Suppose 8 eligible non-pinned posts span exactly 14 days. The observed-interval estimate is 7 × (8 − 1) ÷ 14 = 3.5 posts per week. This hypothetical value describes those intervals. It does not establish a complete 14-day publication total or recommend 3.5 posts per week for another account.
Build the measurement record
- Choose the account and research question.
- Record available source URLs, publication timestamps, formats and pinned status.
- Record when the sample was observed and which posts or fields may be missing.
- Deduplicate identities within the account’s sample.
- Apply the selected method and retain its eligible count and date span.
- Keep each account’s coverage separate when comparing accounts.
When measuring one account’s observed feed activity, count a shared collaboration post once within that account. When counting unique content across several accounts, deduplicate shared post identities across the set. Those are different questions, so document which one you answer.
Formats and excluded content
Keep unknown formats separate and avoid counting a Reel twice merely because it appears in multiple views. V5’s captured post cohort does not establish a historical archive of Stories. Do not include uncaptured posts in the calculation or infer missing publication dates.
Describe patterns without inventing causes
A cluster of dated posts can be described as a burst in the sample. It does not prove a funded campaign. A quiet period does not prove a staffing problem, and resumed activity does not prove a rebrand or agency change. Inspect source context before proposing explanations.
Report individual account results with their counts and windows. A blended average can hide differences, but a range is also only as representative as the selected accounts and source coverage. A short window may be noisy; a long one may mix several publishing patterns. There is no universally sufficient lookback period.
Use the result to plan a test
Choose a schedule your team can sustain, define the outcome to measure and use your own authorized analytics to evaluate it. Competitor cadence supplies context. It does not identify audience availability or an algorithmic reward for a specific frequency.
Using Instaseer
The posting-frequency tool shows the returned posts and calculation coverage. Retain that context with the result and inspect the methodology. For a broader review, use the competitor checklist.

Common questions
How often should a brand post?
This guide supplies no universal schedule. Treat observed cadence as context and test an appropriate plan on your own account.
Can a limited sample establish complete monthly activity?
No. Distinguish a returned sample’s observed-interval estimate from a count over a verified complete calendar window.
Should I overwrite last month’s result?
Keep separately dated observations if you need to compare change, including any differences in coverage or method.
