Bot blocking
Only real people reach your pixel
Free trial. No card, no tag manager.
Filtered before it reaches Meta
Crawlers, scrapers and automated traffic fire page views and sometimes conversions. PixelFlow recognises non-human requests and drops them before any event is sent to Meta, with nothing to configure.

Known bots and crawlers
Search engine crawlers, link previewers, uptime monitors and scrapers are recognised and dropped.
Cleaner optimisation signal
Meta learns from the events you send. Removing fake events keeps its optimisation pointed at people who buy.
Visible in the log
Blocked traffic is recorded with the reason, so you can see how much was filtered without it inflating your results.

It works because PixelFlow sits in between
With a plain pixel there is nothing between the visitor and Meta. PixelFlow receives every event on its own servers first, which is where it can inspect the request and decide whether it belongs to a person.
Add your own blocking rules on top
Beyond automatic bot detection you can decide when an event should not fire at all: only once per session, only when a click ID is present, or not again within a set window.

Attribution you can trust
Bot traffic does not just waste ad spend, it skews your source numbers. Filtering it keeps the attribution table and revenue per session honest.
FAQ
Everything you need to know about bot filtering.
Do I need to turn bot blocking on?
No. It is on for every site and every plan.
Will it block real customers using privacy tools?
No. It filters known automated traffic, not people using ad blockers or private browsing.
Can I see what was blocked?
Yes. Blocked events appear in the event log with the reason.
Does it affect page speed?
No. Detection happens on PixelFlow’s servers, not in the visitor’s browser.
Does it stop click fraud on my ads?
It stops fake events from reaching your pixel. It does not control who clicks your ads, but it stops those clicks from being counted as conversions.
Can I block specific traffic myself?
Yes, with blocking rules per event, such as ignoring events without a Facebook click ID.
