Conversion diagnostics
Conversion Diagnostic Tools
Tools that help you find where a funnel is leaking and why leads or conversions dropped — so you know the area to investigate before you change anything.
Conversion drop diagnostic
Compare your funnel across two periods and find whether the leak is in traffic, the landing page, or the form.
Lead drop checker
Classify a lead drop as a volume, conversion rate, cost efficiency, or CRM handoff issue.
Form submit rate calculator
See your visit-to-form-view, form-view-to-submit, and overall rates, and spot form friction.
Find the stage first, then the cause
Every conversion funnel is a chain of ratios. Visitors become form viewers, form viewers become submitters, and submitters become leads in whatever system your team actually trusts. A drop in the final number can come from any link in that chain, and the fix for each link is handled by a different person.
That is why diagnosis starts with the stage rather than the cause. A traffic problem is a media problem. A page problem is a design or content problem. A form problem is usually a build problem. A handoff problem is an integration problem. Working out which of those four you have takes minutes and saves the far longer argument about whose fault it is.
The three tools here each take one slice of that chain. None of them needs access to your accounts, because they work on figures you can read off your analytics and your CRM by hand.
Reading the result
Once you have the comparison, the shape of the numbers tells you where to go next.
- Sessions down, rates flat. The funnel is healthy and the traffic is not. Look at channel volume, budget, seasonality, or a tracking change that stopped counting sessions.
- Sessions flat, form views down. People arrive and leave before reaching the form. Look at page load time, above-the-fold content, and anything that changed in the layout.
- Form views flat, submissions down. People see the form and do not complete it. Look at added fields, validation errors, and mobile rendering.
- Submissions flat, leads down. The funnel works and the delivery of those leads does not. Look at the CRM integration, the destination inbox, and any automation that routes or filters new records.
The last case is the one that goes unnoticed longest, because every marketing dashboard in the chain still shows green while the pipeline empties.
Frequently asked questions
- What counts as a conversion drop worth investigating?
- A drop is worth investigating when the conversion rate moved, not just the raw count. If sessions fell by a third and conversions fell by a third, the funnel is behaving exactly as it always did and the question is a traffic question. If sessions held and conversions fell, something inside the funnel changed and that is what these tools are for.
- How much data do I need for the comparison to mean anything?
- Enough volume that a handful of conversions either way does not swing the rate. As a rough floor, a period with fewer than about thirty conversions will produce a rate that moves on noise alone. If your volume is lower than that, compare longer periods rather than shorter ones.
- Which stage is most often the real culprit?
- In our experience the two most commonly missed are the form itself and the handoff after it, because neither shows up in an ad platform and only the first shows up in most analytics setups. A form that silently stops submitting and a CRM integration that stops accepting records both look like a marketing problem from the outside.
- The numbers say the landing page. What do I check first?
- Check what changed on the page and when. A deploy, a content edit, a new required field, a changed button, a third-party script that started failing, or a consent banner that now covers the form on mobile. Line the date of the change up against the date the rate moved; if they match, you have your answer without needing to prove it any further.
- Can these tools tell me the cause, not just the stage?
- No, and that is the honest limit of a calculator. A calculator can only compare numbers you give it. Finding the cause means knowing which change happened just before the drop, which requires a record of your ad, page, form, and CRM changes over time. That record is what the Quarkad product keeps.
