Every advertiser has had this argument with their own dashboard. Conversion Troubleshooter puts Google Ads' conversion count next to your actual calls and form submissions for the same date range, breaks it down per tracking number, and shows you exactly where the gap comes from — so you can fix the tracking instead of distrusting every number after it.
What it does
The tool exists because the two numbers are produced by two different systems with two different definitions. Seeing them together is most of the diagnosis.
Google Ads' conversions on one side, the calls and form submissions PPC TNT actually recorded on the other, over the date range you pick.
The difference, stated plainly, rather than left for you to subtract and puzzle over.
Split by tracking number, which is usually where the answer is — one number over-counting, or one nobody pooled.
The single most common cause of an inflated count. Flip it and see whether repeat callers explain the whole gap.
Pulls from Google Ads and CallRail at the moment you ask, because the stored tables don't carry "all conversions", first-time flags, the dialled number, or forms at all.
Your date range and toggles are remembered per workspace, so checking the same client next month is one click.
What it surfaces
Two counts, one date range, a per-number breakdown — and an answer instead of a support ticket.
