Why do my Cloudflare visit numbers change when I look again?
The Cloudflare help pages give 4 common reasons. The first to rule out: Cloudflare can read a different share of the data each time the same question is asked, so a total can shift a little between looks.
What causes it?
Cloudflare can read a different share of the data each time the same question is asked, so a total can shift a little between looks.
In the Cloudflare help:
ABR may choose different sampling resolutions on different query runs based on system conditions.
GraphQL API inconsistent results, read 2026-11-12.Looking at a long time range in one go can mean more sampling, so a monthly view can differ from the sum of its days.
In the Cloudflare help:
Querying 30 days at once is an expensive operation that triggers more aggressive sampling.
GraphQL API inconsistent results, read 2026-11-12.When Cloudflare's systems are busy, they can sample more heavily to share resources fairly.
In the Cloudflare help:
During high-traffic periods, the system may apply more aggressive sampling to ensure fair resource distribution.
GraphQL API inconsistent results, read 2026-11-12.Busy sites are the ones most likely to see sampled figures, because counting every request would be impractical.
In the Cloudflare help:
Sampling is typically applied to very high-traffic datasets where full data analysis would be impractical.

How do I check it myself?
Look for the dashboard's note of how much data was sampled before reading a change as real.
In the Cloudflare help:
Displays an icon with the sampled percentage of data, if sampled data was used for the visualization.
Understanding sampling in Cloudflare Analytics, read 2026-11-12.Compare day by day or week by week instead of a whole month at once.
In the Cloudflare help:
Instead of querying an entire month at once, break queries into smaller intervals (daily or weekly).

How does Cloudflare work with Feder?
- Connect Cloudflare to Feder and it joins your Visits apps.
- When you connect Cloudflare, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in Cloudflare, one of your Visits apps. Feder only reads. It never changes anything in Cloudflare.
