Cross-platform blocking across your ad platforms
Block across ad platforms is a switch on the Detection features tab of a rule set (Setup > Rule sets). With it on, a visitor that Tapper Block flags after a click on one ad platform is blocked on your other protected platforms too. It is off by default.

How it works
With the switch off, a detection stays on the platform that produced it. With it on, the visitor is excluded on every protected platform of the entity: a visitor flagged after a Meta click is also excluded from your Google Ads campaigns, and the other way round.
Each platform gets the exclusion that suits it: IP and audience exclusions on Google Ads, an audience exclusion on the Meta ad sets and Microsoft Ads campaigns you protect, and a recorded click on TikTok Ads. See How Block protects Meta ads and How Block protects TikTok ads.
- The switch is always shown, but only makes a difference when the entity has more than one ad platform connected and protected.
- It belongs to the selected rule set, so it can be on for one set and off for another. See Rule sets: apply different rules to platforms, ad accounts or campaigns.
- In Monitor-only, Tapper writes no automatic exclusions on any platform, so the switch has no effect until blocking starts. See Switch blocking on or off.
Turn it on
- If your workspace has more than one protected entity, pick it in the switcher at the top of the sidebar.
- In the sidebar, under Setup, click Rule sets. Pick the set under Ad campaigns and open its Detection features tab.
- Turn on Block across ad platforms. It saves the moment you click it.
Where cross-platform blocks show up
The Exclusions page lists what Tapper excluded, one list per platform (Google Ads, Meta Ads, TikTok Ads and Microsoft Ads). A visitor blocked because of a detection on another platform carries the reason Blocked on another platform in that list. So a visitor flagged after a Meta click appears in the Google list with that reason, while the Meta list shows the original reason.
On a monitor-only workspace the page is titled Flagged traffic. See The Exclusions page and the proof drawer and Block reasons explained.
