How to use this tool
Paste a URL to inspect its scheme, host, query names and values, fragment and possible tracking markers. Duplicate keys are listed; parameter names are compared case-sensitively after decoding.
Worked example
https://example.com/?ref=a&ref=b&utm_source=email#pricing contains a duplicate ref key, a UTM source and a pricing fragment. None proves that affiliate attribution works.
Important limitations
Structural checks do not validate a merchant account, redirects, destination availability, cookies, attribution or commission credit. No remote URL is fetched. Malformed percent escapes and dangerous schemes are rejected.
