Paste a page with an embedded form. We inspect the public frame and page tracking surface without submitting a lead or pretending cross-origin content is visible when it is not.
Paste the page that embeds the form. We passively inspect the observable frame and tracking surface; we never submit a form or bypass iframe boundaries.
This tool answers: Is an embedded iframe form wired to hand off a successful conversion?
Enable JavaScript to run the check — the diagnosis itself is free and needs no account.
An embedded form often lives on a different domain from the marketing page. A parent-page click listener cannot reliably see a successful frame submission, and the provider may need a callback, postMessage bridge, or thank-you redirect instead.
The form can look identical to a native form while its conversion event fires too early, never reaches the parent page, or lacks the campaign context needed for attribution.
These answer the questions this one tends to raise.
So you can trust the result — and your developer can verify it.
The check inventories passive form and tracking signals exposed in the capture. Cross-origin content is reported as a boundary, not bypassed.
A page-load event may be useful evidence, but a successful frame submission needs the provider's documented callback and a controlled test.
