Feature
Form analytics
Form analytics shows how many people complete each step of your form and how many finish it. You find the step where leads give up and fix that step first.
What is form analytics?
Form analytics is the measurement of how people move through a form, from the first question to the completed lead. On a multi-step form it counts the people who complete each step, which shows you where the others stopped.
How does form tracking work in Growform today?
Form tracking in Growform works today by sending events to Google Analytics 4. The form sends one event each time a step is completed and another when the whole form is completed. Every event carries the form's ID, and a step event also carries the number of the step.
Built-in analytics is planned for 2026. If you manage your own tags, the form's events are also available to a custom Google Tag Manager container on Professional plans and above.
How do you measure form abandonment?
You measure form abandonment with a funnel exploration in GA4 that has one funnel step for each step of your form. The report shows how many people completed the first step, how many of those completed the second, and so on to the finished form. The largest fall between two steps marks the question to examine first.
How do you calculate form conversion rate?
Form conversion rate is the number of completed forms divided by the number of people who were shown the form. The funnel gives you the same rate for every step, so you can tell a form that loses leads at the first question from one that loses them at the phone number.
How to track form drop-off in GA4 today
Create two custom dimensions
In GA4, create custom dimensions for the formId and stepNumber event parameters. GA4 can take 24 to 48 hours to process them.
Build a funnel exploration
Open “Explore” in GA4, choose “Funnel exploration” and add one funnel step for each step of your form.
Read the drop-off
Compare the counts between neighboring steps and note where the largest share of leads leaves.
What step-level data changes for your campaigns
- You fix the step that loses the most leads.
The funnel reports the drop between each pair of steps, so a solar form that loses people at the electricity bill question shows it in the counts.
- You can measure the effect of every edit.
After you reword a question or move the contact step, the completion count for that step tells you whether the edit helped.
- Form data sits beside your traffic data.
The events go to the GA4 property you already use for your website, where your traffic reports are kept.
- Ad platforms hear about the completed form too.
Growform can fire a conversion to Google Ads, the Meta Pixel, Microsoft Advertising and X when the form is completed.

Frequently asked questions
When does built-in form analytics arrive?
Built-in form analytics is coming in 2026. Today the form reports each step to Google Analytics 4, and the funnel is built there.
Do I need GA4 on my landing page first?
Yes. GA4 has to be running already on the page that holds the form. Growform sends its events to that installation and adds no base tag of its own.
Can I keep two forms apart in one GA4 property?
Yes. The formId parameter holds the 24-character ID of the form, and you can filter a funnel by it.
