How do I check that TapCub is collecting data?

Step 1: watch Realtime

Open Web analyticsRealtime and load a page of your site in another tab, on the domain you registered. The pageview appears within a few seconds with its path and title. If it does, you are done.

Use a normal browser window. A browser that sends Do Not Track or Global Privacy Control, or a headless browser driven by Puppeteer or Playwright, may not show up; see why there is no data.

Step 2: check two requests

If Realtime stays empty, open the browser’s developer tools, go to the Network panel and reload the page:

1. client.js loads. If it is missing, the snippet is not in the page that was served (often a cache), or an extension blocked it.
2. A POST to /api/v1/pulse follows. The first one is a normal fetch request; later ones may be listed with the type “ping” because they use sendBeacon. If client.js loaded but no POST follows, the script stopped itself: Do Not Track, Global Privacy Control, localhost or an excluded path.

Step 3: look for rejected hits

If the POST is there but Realtime stays empty, the hit was dropped on our side. DataData quality counts these per day by reason: domain mismatch, site paused, exclusion rule, monthly quota and more. The reason tells you which setting to change; the troubleshooting guide lists the fix for each.
