Frequently asked questions
Does this tool test that the landing page is online?
No. Fetching arbitrary websites would require cross-origin permissions and may reveal the page you are auditing. This tool only analyses the pasted URL locally.
Which tags are essential for clear GA4 campaign attribution?
Source, medium and campaign are a useful minimum for consistent manual tracking. Other tags can add context.
Can duplicate UTM tags cause trouble?
Yes. Multiple values for the same parameter can be ambiguous to analytics systems. Prefer one value for each key.
